Prototype stage · recruiting trial apiaries

Varroa control that doesn't come out of a packet.

BeesDefender is an in-hive device that finds Varroa destructor on your bees using computer vision, and removes each mite with a low-power laser pulse. The bee walks on.

No strips. No supers-off window. Non-chemical, no residue. No known resistance mechanism.

We're at prototype stage, not shipping — and we say what that means. There's an honest status update further down this page.

Concept visualisation of the detection overlay. Real camera frame; the mites on adult bees are actual detections, the open-cell target is illustrative.

The situation

Australia went from varroa-free to resistant varroa in under four years.

Eight varroa products are approved for use in Australia. Four of them no longer work where resistance has been confirmed — and resistance is now confirmed in four states.

  1. Jun 2022First detection. Varroa destructor found in sentinel hives at the Port of Newcastle. Australia had been the last major honey-producing country without it.
  2. Sep 2023Eradication abandoned. The National Management Group concludes eradication is no longer achievable. Around 47,000 colonies had already been euthanised.
  3. Apr 2025ACT. First detection at Kowen. More than 1,000 hives destroyed in the first year.
  4. Sep 2025South Australia. Found in the Riverland, in a Queensland consignment brought in for almond pollination. A second, unrelated detection follows in November.
  5. 6 Feb 2026The national programme ends. The National Varroa Mite Management Program ceases. There is no single national successor — support is now state-by-state, with AHBIC coordinating.
  6. Jan–May 2026Both first-line chemicals fail. Pyrethroid resistance confirmed in northern NSW (January), SE Queensland (March) and north-east Victoria (May). Amitraz resistance confirmed in SE Queensland on 30 March, then NSW and SA.
  7. TodayFive jurisdictions have varroa — NSW, QLD, VIC, SA and the ACT. Only Western Australia, the Northern Territory and Tasmania remain free.

The most important finding of 2026 isn't that resistance arrived. It's how.

When the affected apiaries were tested, the mites didn't show the gradual spread you'd expect from resistance evolving locally over generations. They were either fully resistant or fully susceptible, with nothing in between.

“Currently the tested mites have either been 100% resistant or highly susceptible with no in-between, which is not what you would expect if it was locally grown resistance.”

“There is a strong likelihood that this could be a new varroa population entering Australia, rather than resistance developing from the existing mite population.”

Danny Le Feuvre, CEO, Australian Honey Bee Industry Council

If that's right, resistance didn't arrive on a slow evolutionary clock that a new chemical could reset — it walked in already carrying it.

Whether that's what happened, nobody knows yet. It's the reading the industry's own peak body put on the record after one round of testing, and it fits the pattern — but it isn't proof. Le Feuvre is careful about it himself: the same finding, he notes, “suggests this is not yet a widespread national issue”. Another season of testing will tell us more, and it may turn out otherwise.

For beekeepers

Ten work weeks a year, on varroa alone.

The 2024 Australian COLOSS Survey (Holmes & Mikheyev, ANU, published by AHBIC in October 2025) measured what varroa management actually takes out of a NSW operation.

Materials and labour-time figures are from the COLOSS survey. The all-in stack is our own estimate built on top of them, at a A$50/hr loaded labour cost. Your numbers will differ.

Varroa is extra work for everyone. For a thousand-hive operation it added roughly 250–390 hours a year — hours that have to come out of people already working 50-hour weeks.

The money shows up on a spreadsheet. The hours don't — and they're the part you can't buy back. That's the section below →

The labour problem

The hours are the part you can't buy back.

You can absorb a price rise. You can pass some of it on. What you can't do is conjure another 390 hours a year out of a workforce that is small, ageing, and has almost no pipeline behind it.

49Median age of an Australian beekeeper. The national median worker is about 40
50hrsAverage full-time week, against a 38-hour standard
26%Hold any Certificate III or IV. Around 41% have no post-school qualification at all
3TAFE providers offering Certificate III in Beekeeping, nationally

Who's actually left to do it

Around 1,600 people are formally employed as beekeepers in Australia — against roughly 1,870 commercial enterprises. That gap tells you what the industry really runs on: owner-operators, family labour and casual seasonal hires.

40% of that workforce is over 45 and 20% is over 55. And 85% of it sits in the eastern states that now have varroa.

The work is also lumpy — pollination from August, extraction from November, then a long quiet stretch. That shape is exactly why permanent hires are hard to justify, and exactly why a new year-round task lands so badly.

Why you can't simply hire your way out

Training. Three providers nationally for a population of about 47,900 registered beekeepers. Tocal runs a staged selection process because demand exceeds places — applicants are being turned away.

Skilled migration. Apiarist is on the Core Skills Occupation List, which is a real signal the occupation is recognised as skilled. But assessment runs through VETASSESS and wants a degree or five-plus years documented, and the end-to-end timeline is typically 12–24 months at A$1,000+ in assessment and A$4,000+ in visa fees. It is not a fix for next August.

PALM. Pacific labour works for the peaks, but the compliance, accommodation and pastoral-care obligations generally only pay above about a thousand hives — and award rates still apply. It solves availability, not cost.

And then there's succession

A fifth of the workforce is inside a normal retirement window. Building a 500-hive operation from scratch now takes A$200,000+ of capital. Children move to cities; fifty-hour outdoor weeks are a hard sell.

The successors who do come in tend to look different from the generation before them — smaller operations, more pollination-focused, more comfortable with a phone in the equation.

That isn't a market we're guessing at. It's the reason this is designed to be dropped in and forgotten, rather than for someone who enjoys tinkering.

Put it together and the arithmetic only goes one way. An ageing workforce, a training pipeline that can't scale, a migration pathway measured in years, and a brand-new parasite that adds 23.5 minutes to every hive, every year. Either output per person rises, or hive numbers fall.

That's the whole reason this device exists. Not to replace your judgement — to give you back the hours, at a moment when those hours are the hardest thing in your business to find.

Workforce figures: Jobs and Skills Australia; training data from training.gov.au; migration settings from the Department of Home Affairs. One honest caveat — the official 2025 Occupation Shortage List still rates apiarist as “No Shortage”, because the formal employee market is too small to register on standard labour-market indicators. AHBIC is pushing for that to be reviewed in the 2026 survey. We'd rather tell you that than quietly claim a shortage the government hasn't recognised.

The bill you don't get invoiced for

What the treatment costs the colony.

Strips and vapours are counted in dollars and minutes. There's a second bill that never shows up on an invoice — it's paid in wax, in drones, in queens, and in what your packer finds when they test.

It doesn't leave when the strip does

Miticides dissolve in fat and wax rather than in water. So when a strip comes out, the chemical doesn't come out with it — it has already soaked into the beeswax, and it stays there.

Honey gets harvested and replaced every season. Wax doesn't. The same comb goes back in year after year, so each treatment adds to what's already in it.

In wax sampled from more than 250 US commercial operations, miticides were the most prevalent pesticide class found. Coumaphos in particular builds up in comb with repeated use.

Fisher & Rangel 2018; Dai et al. 2018

Drones reared in that wax mate worse

This is the finding that should give any queen breeder pause. Drones reared on comb coated with miticide-contaminated wax at field-realistic concentrations produced markedly less viable sperm:

Control99.2%
Amitraz-contaminated wax80.1%
Fluvalinate + coumaphos wax80.0%

Roughly 19 percentage points of sperm viability, from residue already sitting in ordinary commercial comb.

Fisher & Rangel, PLOS ONE, December 2018

And a queen is only as good as her mating

A queen mated to drones with 80% sperm viability starts her laying life with a smaller, poorer sperm store. That shows up later as patchy brood, early supersedure and a colony that never quite builds — often long after anyone connects it to a treatment two seasons ago.

Some treatments cost queens directly and immediately. Formic acid is the clearest example: beekeepers report 5–15% queen loss per treatment, and above about 29°C the risk to queens and brood climbs sharply.

Your buyer is testing for it

Residue is a commercial problem as well as a biological one. Packers and exporters test, and a downgraded or rejected line is expensive in a way that has nothing to do with what the strips cost.

Then there's the production hit you already know about: supers off, a 14-day withdrawal, and a honey flow you can't work through. That's ~A$16 a hive in our cost stack, and it lands in the weeks worth the most.

Where we'll be straight with you. The evidence isn't uniformly damning, and we're not going to present it that way. A 2018 chronic-toxicity study fed amitraz, coumaphos and fluvalinate to larvae at concentrations matching the maximum residues found in real pollen and honey, and found no detectable change in larval survival or development rate. Only much higher doses did harm.

So the honest position is narrower than “chemicals are poisoning your brood”. It is: residues accumulate in wax, and the best-documented consequence is reproductive — drones and, through them, queens. Plus the queen losses and the disturbance that come with the application itself.

What changes when the treatment isn't a chemical

Nothing added to the wax. A laser pulse leaves no residue, so it doesn't contribute to the load already in your comb. It won't clean out what's there — old comb is old comb — but it stops adding to it.
No supers-off window. Strips can’t be in the box while the supers are on, so treating and making honey compete for the same weeks. Nothing chemical goes in here, so they don’t.
Nothing that kills queens. No formic-acid queen-loss event, no thermal excursion past the temperature brood tolerates.
Fewer lids off. Every opening is a disruption — brood chilled, propolis broken, the colony's day interrupted. A device that runs on its own is one fewer reason to be in the box.

And the obvious question back: is a laser itself harmless to the bee? We don't know yet, and nobody does. That's precisely why an independent, peer-reviewed bee-safety study — sub-lethal effects, foraging, learning, brood viability, queen acceptance — is something we've committed to publishing before we sell anything. It would be absurd to argue chemical treatments have hidden costs and then wave away our own.

Dai et al., “Chronic toxicity of amitraz, coumaphos and fluvalinate to Apis mellifera L. larvae reared in vitro”, Scientific Reports 8:5635, 2018 · formic acid queen-loss figures are beekeeper-reported ranges, not a controlled trial. Note that coumaphos and fluvalinate are not registered for varroa use in Australia — they matter here because they are what the international wax-residue literature is built on, and because Australian comb is not exempt from the same chemistry arriving by other routes.

The gap we're built for

Oxalic acid is now the backbone. It's weakest exactly when you need it most.

With Bayvarol and Apivar compromised, Australian beekeepers have been pushed onto oxalic acid, formic acid, thymol and IPM. That's the right advice, and it works.

But oxalic acid is most effective when there's little or no brood in the hive. Its effectiveness is compromised during the high-brood months — which in Australia are the honey production months. The same months when you can't have a chemical strip in the box either.

That window — brood heavy, supers on, no good chemical option — is the window BeesDefender is designed to cover. Not instead of your programme. Underneath it, running continuously, for the months when everything else has to stop.

How it works

Install. See. Remove. Report.

A unit sized for the Langstroth box you already run, with as little change to your routine as we can engineer.

Install

Slide the Defender Blade into your brood box in place of one frame. It's built to Langstroth frame dimensions, so it goes into the boxes you already run.

Computer vision separates a varroa mite from the bee carrying it. A mite's dark exoskeleton reflects very differently from a bee's body — that difference is what the model is trained on.

Remove

An X–Y positioner puts a single low-power laser pulse on the mite, calibrated to destroy the mite with the minimum thermal rise we can achieve in the bee carrying it and in any surrounding brood. The bee keeps walking.

A mite count per hive, every morning, on your phone. Not an inference from temperature or sound — a count of mites actually found and actually removed.

Which also means you can show a grower a curve instead of arguing about an alcohol wash sample.

Built to fit a box designed in 1852

The Langstroth frame was patented in January 1852 and it is still the standard in Australian commercial beekeeping. Any device that asks you to replace your fleet is asking too much.

So the Defender Blade is built to Langstroth frame dimensions — into the equipment you already own, on the pallets you already truck, in the yards you already run.

Other frame sizes are in the works. Langstroth full-depth is where we're starting because it's the commercial standard here, but we know plenty of operations run WSP supers and other depths. If you run something else, say so on the trial form — it's how we decide what to build next.

Design work is ongoing and details are held back pending a provisional patent filing. What's shown here is concept-level.

Working the brood cycle

Two moments matter more than all the rest.

A varroa mite's whole reproductive strategy depends on two events: slipping into a brood cell just before the bees cap it, and walking back out when the young bee emerges. Both happen on the outside of the wax. Both run to a schedule. Both are visible to a camera that is already looking.

1

Before the cell is capped

The blade scans the uncapped cells in front of it every day. Larval development runs to a known timetable, so a cell that is a day or two from being capped looks different from one that isn't — and the daily record shows which way it is heading.

That's the window. Clear the mites out of a cell in the day before the wax goes on, and those mites don't get sealed in to breed. Fewer mites go under cap in the first place.

2

When the cell opens again

The same timetable runs forwards. A cell capped on a known day is due to emerge on a known day, so we know which cells are about to open before they do.

When one does, the founder mite and her mature daughters come out with the young bee — all at once, all in the open, all on a surface we are already watching. That is the most concentrated target the mite ever presents, and it happens on a schedule.

In between, we genuinely can't see them

Once the wax is on, the mites inside are beyond us. No optical system sees through a capping and we're not going to suggest otherwise.

What changes is that the sealed period stops being a free ride. Squeeze the doorway on the way in, meet them at the doorway on the way out, and the population that survives a full cycle is smaller than it would otherwise have been.

None of this is 100%, and we won't claim it is. Some mites will be missed on the way in. Some will emerge on the far side of a frame we aren't watching. Heavy infestations will still want a brood break and an oxalic dribble.

The point isn't perfection. It's pressure on the mite population — applied every day, at the two moments the mite is most exposed, instead of four times a season when you happen to have the yard open.

What we're actually trying to do

Hold mite and parasite pressure down 365 days a year — continuously, in the background — rather than knocking the population back a few times a season and watching it climb again between treatments.

And because the same device has to look at the colony every day to do that, it doubles as a continuous health monitor. Every mite counted is also a datapoint about that hive: what the load is doing week to week, whether a treatment worked, which yards are trending the wrong way, and what you can put in front of a grower at the start of a pollination contract.

Management, not eradication. Measured daily, on every hive, without opening a single lid.

Beyond varroa

One sensor. More than one parasite.

A camera, AI image recognition, an X–Y positioner and a laser is a general-purpose way to find a small foreign object on or near a bee and act on it in milliseconds. What changes between parasites is the training data and the targeting parameters — not the hardware.

Which is why it's called BeesDefender and not VarroaDefender.

Which bee parasites and diseases an optical device can and cannot address
Target Can optics see it? What the device would do Status
Varroa destructorVarroa mite Yes — about 1.1 × 1.6 mm, dark red-brown, high contrast against a pale thorax Detect on adult bees and in open cells, remove, count v1 — all of our focus
Aethina tumidaSmall hive beetle Yes, and more easily — 4–7 mm, dark brown to black, hard oval shell Detect and remove adults moving on comb; log pressure over time Credible v2
Galleria mellonellaWax moth Yes — larvae and adults are large and pale against dark comb Detect and alert; removal is harder than detection Possible extension
Tropilaelaps spp.Not yet in Australia Yes — a similar optical signature to varroa Early warning, primarily. Removal is weaker here — see below Surveillance value
Tracheal miteAcarapis woodi No — it lives inside the bee's breathing tubes Nothing Out of scope, permanently
NosemaN. ceranae, N. apis No — a microsporidian gut pathogen Nothing Out of scope
AFB, EFB, chalkbroodBrood diseases No — bacterial and fungal disease inside sealed brood Nothing Out of scope
DWV and other virusesDeformed wing virus No — not an organism you can point anything at Addressed only by controlling the mite that carries it Indirect only

Small hive beetle — the obvious second target

Australia has had SHB since October 2002. It's established through the warmer eastern coastal strip and turns up in roughly 40% of Australian honey samples. It doesn't kill a colony the way varroa does — it saps strength, and when it finally wins, the larvae slime the frames, the honey ferments and weeps out of the cells, and the colony absconds. Under laboratory conditions 80 beetles became more than 36,000 adults in 63 days.

Today's control is almost entirely indirect: oil traps, lime, diatomaceous earth, in-hive baits, keeping colonies strong, freezing infested equipment. Nothing currently looks at a beetle and removes it.

Optically it's an easier problem than varroa — several times larger, darker, and hard-shelled against pale wax. The harder half is removal: a beetle is armoured and it runs. Different energy, different targeting, real engineering. But the camera is already in the box.

Tropilaelaps — not here yet

Tropilaelaps mercedesae is not in Australia. By May 2026 it had moved out of Asia into Eastern Europe. It reproduces faster than varroa and it already carries deformed wing virus and black queen cell virus — the viruses varroa took decades to acquire.

The honest caveat, and it matters: Tropilaelaps spends only about a day on adult bees, against several days for varroa. A device that removes phoretic mites is less effective against Tropilaelaps than against varroa. We're not going to pretend otherwise.

But it can't survive more than a few days away from brood, and researchers are consistent that delayed detection is what turns an incursion into an epidemic. That's where a camera that never stops watching earns its keep — not as treatment, but as a tripwire in a few hundred hives across the country. Australia has already spent more than A$100 million finding out what late detection costs.

And what it will never do

Anything inside a bee, sealed behind wax, or too small to resolve is out of reach — not in v3, not ever. Tracheal mite lives in the bee's breathing tubes. Nosema is a gut pathogen. American and European foulbrood are bacterial diseases of the brood, and AFB will still mean burning the hive. Deformed wing virus isn't something you can point a laser at; the only handle anyone has on it is the mite that carries it.

We'd rather put that list on the website than let someone find the edges after they've bought something.

None of this is in v1. v1 is varroa, because varroa is what's killing colonies and what just stopped responding to chemistry. Everything above is a reason the same box is worth more in year three than in year one — every unit installed for varroa is a camera in a hive, and a second parasite is a model update and a firmware push, not new hardware in a paddock.

Being straight with you

What it can't do.

You'll ask these questions anyway, and you should. Here are the answers before you have to.

It doesn't see through a wax capping

Nothing optical does. Once a cell is sealed, the mites inside are beyond us until it opens. At any given moment most of the mite population is under cap.

What we do instead is work the two moments either side of it — clearing cells in the day before they're capped, and meeting the mites at emergence. That's set out here. It narrows the doorway. It doesn't remove it, and a heavy infestation will still want a brood break and an oxalic dribble.

It is not a replacement for your IPM programme

Anyone selling you a single answer to varroa is selling you something. This is one component of an integrated programme — the component that runs in the background through honey flow, when a strip can't be in the box and oxalic acid can't do its best work.

Pair it with a brood break, monitor with alcohol washes, keep rotating your modes of action.

It isn't proven yet — and we won't pretend it is

There is no independent efficacy study for this device, because the device isn't finished. We have a working prototype, a detection approach that works on our bench, and a lot of engineering ahead of us.

We've committed to publishing an independent, peer-reviewed efficacy and bee-safety study before we sell anything — including the results if they're bad. The chemical-free corner of this market has a long history of confident claims and thin evidence. We'd rather be slow than join it.

It takes up a frame slot

The Defender Blade goes into the brood box in place of a frame. That's one less frame of brood or stores in that box, and on an eight-frame box it's a real fraction. We're not going to pretend otherwise.

Two things take the edge off it. You can run an extra super to get the space back — nothing about the blade stops you building the box taller. And a queen excluder lets you decide exactly where she lays, so the space you give up comes out of where it costs you least rather than out of the middle of the brood nest.

It's still a trade: one frame, against no strips, no supers-off window and hours back. Whether that maths works at your scale is a fair thing to put to us — and the trial is where you'd find out for your own operation rather than take our word for it.

Where we actually are

Honestly: early.

What exists

  • A working prototype, running on the bench
  • A detection approach that separates mite from bee
  • An X–Y actuator design in a Langstroth-compatible form factor
  • A deep body of market and competitive research
  • A founder with an engineering background, working on this full-time

What doesn't

  • A field-deployable production unit
  • Any efficacy or bee-safety data
  • A price
  • Customers, or a peer-reviewed publication
  • A commercial-beekeeper co-founder — we're actively looking for one
The prototype mounted above a real beehive frame on a workbench.
The prototype, above a real beehive frame. This is the honest state of the hardware.

If that's too early for you, that's a fair call — come back in a season. If it's interesting to you because it's early, the trial programme below is where the useful conversation starts.

Trial programme

We're looking for ten Australian beekeepers.

Not ten customers — ten people willing to let us put a small number of units in a yard, next to whatever you normally do, and tell us honestly what breaks.

The terms, plainly

  • Three to ten hives, instrumented alongside your normal protocol so there's something to compare against.
  • We come to you. Your yard, your workflow, your schedule. Our travel and our time.
  • No cost to you. Units, install, support and data all come free, there's nothing to buy at the end, and no obligation of any kind.
  • You pick the hives — and you can pull a unit out at any time, for any reason, without explaining yourself.
  • Data flows both ways. You get everything we record from your hives, in a format you can keep and use.
  • A mutual NDA before anything goes in a box. Not to tie you up. The provisional patent isn't filed yet and a trial means showing you the inside of the design. It cuts both ways — whatever you tell us about your operation stays with us.
  • Trial partners get first units and priority support when there's something to ship.

And what we're not offering, so nobody's surprised

We're not paying for your time, and we can't underwrite hive losses. We're a prototype-stage company with no revenue. We'd rather say that plainly now than write a cheque we can't back later.

What that means in practice: start small. Three hives, not thirty. Pick hives you could afford to be wrong about. Pull the unit the moment anything looks off. We would much rather you ran a cautious trial you're comfortable with than a big one you end up regretting.

If that makes it not worth your while, that's a completely fair call and no hard feelings. We'd still like to hear what your last varroa season was actually like — that conversation is worth a lot to us on its own.

We're deliberately looking for a spread — large almond pollinators and smaller operations, resistance hot zones and states that are still varroa-free, people who love hive tech and people who've been burned by it. If you've publicly criticised a hive-tech vendor before, we'd particularly like to hear from you.

On price

We haven't set one, and we're not going to guess in public. What we can tell you is the test it has to pass: it has to make sense against roughly A$62 per hive per year today, heading for A$85–110 as resistance forces the rotation to formic acid and IPM. If we can't land somewhere defensible against that, we don't have a product and we'd rather find out now.

On Combplex

Combplex in the United States has been working on laser varroa control since 2018 and announced pre-sales of their first 100 laser frames in February 2026. They're real, they're good, and they got here first. We're not going to pretend otherwise.

Where we differ is the mechanism. Their detector is a stationary array set into the corner of a frame, reading bees as they pass it. Ours moves — an X–Y positioner that scans the comb face itself. That's what makes the brood-cycle work possible: reading which cells are close to capping and clearing them first, and knowing which are about to open so we're there when they do. It's aimed at a different part of the mite's life rather than being a better version of the same idea.

Most commercial beekeepers already run multi-vendor stacks. Two laser companies in a market this size isn't strange.

For investors & government

A narrow window in a market that just lost its default answer.

>A$100MAustralian public money already spent on the varroa response
A$4.6BDefensible annual value of honey-bee pollination to the economy
~1,870Commercial beekeeping enterprises, ~630,000 hives available for paid pollination
~A$60MPaid to beekeepers for 2026 almond pollination alone

The window

The national management programme ended in February 2026. Both first-line synthetic miticides were confirmed resistant within months, across four states. No optical or laser-based control is available in the Australian market today.

That window is 12–24 months and roughly six of them have already gone.

Why the customer is reachable

Around 70% of Australia's paid pollination revenue flows through 10–15 large operations and a few hundred mid-tier ones. This is not a fragmented consumer market — a direct sales motion targeting the top 200 operators reaches most of the addressable value.

Why a device rather than a sensor

The in-hive monitoring category has been attempted repeatedly for a decade — ApisProtect, Pollenity, OS Beehives — and has consistently failed to scale past pilots. Telling a beekeeper their mite load is high doesn't help when the chemical they'd reach for no longer works.

Beewise has separately proven the market pays subscription pricing for advanced bee tech, raising roughly US$170M. Their bet is full hive replacement. Ours is retrofit, at a fraction of the adoption friction.

The risks, since you'd find them anyway

Structural

Optical control can't reach capped brood. The product is necessarily a continuous IPM component, not a standalone treatment. We position it that way deliberately.

Competitive

Combplex is 12–24 months ahead on optics. If they sign Australian distribution before we ship, the local window closes fast. The University of Auckland's Photon Factory is working on hive-entrance laser detection and reaches its commercialisation phase around now.

More than a quarter of new Australian almond plantings in the last three years are self-fertile varieties that need fewer bees. Almonds anchor Australian paid pollination. That's a real long-term headwind.

Execution

Hardware in agriculture is capital-intensive with long sales cycles, and this is currently a solo founder. Recruiting a commercial-beekeeper co-founder is the top priority and we treat it as non-negotiable.

We're preparing a pre-seed raise and pursuing non-dilutive co-funding. Detailed market sizing, unit economics and the full risk assessment are available on request under NDA.

Who's behind it

One engineer, so far.

Hin Lam — founder

Computer engineering at HKUST, then twenty years building systems that had to keep working when nobody was watching: machine learning and natural language processing from 2008, enterprise infrastructure through the virtualisation-to-multi-cloud transition, and several years inside a global container shipping line where the software ran real freight, not slideware.

BeesDefender started from a straightforward observation. Detecting a small dark object on a moving surface and acting on it in milliseconds is a solved problem in industrial machine vision. It has not been solved inside a beehive, in a paddock, on a solar panel, for a price a beekeeper would pay.

And what's missing

An engineer building beekeeping equipment without a beekeeper is a bad idea, and we know it. The single most important thing we're looking for right now is a commercial beekeeper as co-founder or anchor advisor — someone who has run a varroa season at scale and will tell us when we're wrong.

We're also looking for an optics or photonics engineer with field-deployed product experience, and an academic apiculturist to co-design the efficacy and bee-safety studies.

Questions

The ones we actually get asked.

Lasers can't kill the mites under brood. So what's the point?

Spot on — optics can't see through wax. But a mite has to get into a cell before it's capped, and it has to come back out when the bee emerges. Both of those happen in the open, and both run to a schedule we can read from scanning the same frame every day.

So we clear cells in the day or two before they're capped, and we're watching when they open. Fewer mites get sealed in; fewer walk away unchallenged at emergence. The full explanation is here.

It isn't perfect and we don't pretend it is. What it does is keep pressure on the mite population every day — and on the other parasites we add over time — rather than four times a season — and heavy loads will still want a brood break and an oxalic dribble.

You say "no known" resistance mechanism. Why the weasel word?

Because a flat "no resistance, ever" would be a claim about evolution that nobody can back, and you'd be right to distrust it.

There's no known biochemical route for a mite to become resistant to being physically destroyed. That's genuinely different from a chemical that binds to a receptor — with amitraz or flumethrin a single point mutation is enough, which is exactly what's happened here: L925I for the pyrethroids, Y215H for amitraz. Nothing equivalent exists for a photon.

But mites are under selection pressure from anything that kills them, and behaviour is a plausible route. Mites that spend less time on adult bees, or avoid a lit transit path, or ride in positions that are harder to see, would be selected for. Nobody has tested that, because nobody has run a device like this across enough seasons to find out.

So: no known mechanism, far narrower than chemistry, and not zero. We'd rather say that now than walk back an absolute in five years.

Combplex is already doing this in the US. Why you?

Combplex is real and doing good work. They've been at laser varroa control since 2018, announced pre-sales of their first 100 frames in February 2026, and got here before us. We're not going to pretend otherwise.

The difference is what the device does. Theirs is a fixed detector array in the corner of a frame — bees walk past it, and mites riding on them get hit. Ours is an X–Y positioner that scans the comb face itself, which is what lets us work the brood cycle: clearing cells in the day or two before they're capped, and being there when they open. That's set out here.

Beyond the mechanism: a different form factor, other frame depths on the way, and a pricing model we haven't fixed yet. And most commercial beekeepers already run multi-vendor stacks — two laser companies in a market this size isn't crazy.

Does it only do varroa? What about small hive beetle?

v1 is varroa only, and we'd rather be clear about that than sell you a roadmap. But the mechanism isn't varroa-specific — a camera, an X–Y positioner and a laser is a general way to find a small foreign object on a bee and act on it. Small hive beetle is the obvious second target and optically it's an easier problem than varroa: several millimetres rather than one and a half, darker, and hard-shelled against pale wax. Removing an armoured beetle that runs is the harder half, and we haven't solved it.

The full list of what we think this can and can't ever reach — including the things it will never touch, like nosema, foulbrood and tracheal mite — is set out here.

Will the laser hurt my bees? What about the queen?

It's the concern we take most seriously. We're commissioning an independent, peer-reviewed bee-safety study — sub-lethal effects, foraging, learning, brood viability, queen acceptance — before any commercial sale. If the science doesn't come back clean, we don't ship. Full stop.

On the hardware side, the design target is a fully enclosed IEC 60825 Class 1 product, which means no eye-safety obligations land on you as the operator. Anything above Class 1 would put radiation-safety licensing onto beekeepers, and that's not a product anyone should build.

Do I really want to start fiddling with electronics in my hives?

Fair question, and the whole design point is that you don't fiddle. Drop it in at the start of the season, take it out at the end. Telemetry is on your phone if you want it. If you don't want a phone in this conversation at all, we'll send you a printed monthly report.

The bees will chew it, propolise it, and glue the optics shut.

Yep. That's the engineering problem we spend most of our time on — optical surfaces, wire routing, heat dissipation, form factor. All of it has to survive a real apiary, not a lab bench. Which is exactly why we want a trial in your yard rather than in an office. We'd rather you tell us what's broken than find out eighteen months later.

I tried a sensor system / a hot box / a grooming aid and it did nothing.

We won't trash anyone else's product, but we'll say this: we're building a thing that does something. Sensors that only measure don't change your day. Thermal treatments are temperature-sensitive and can cook brood. The passive grooming category's one independent peer-reviewed trial found no significant effect. We're trying to actually remove the mite, without a chemical and without adding to your workload — and if we can't, we won't pretend otherwise.

I don't trust this "AI" stuff.

There's a lot of hype out there. The vision component does what your own eye does when you watch a bee crawl across a frame — it sees a mite. The model's job is to tell a mite from a bit of pollen. It isn't flying the plane. The decision to remove a varroa is the same physical decision you make when you spot one. We just do it many thousands of times a day, in one hive, without getting tired.

What happens to my hives if your company dies?

Honest answer: hardware companies die more often than software companies do. Two protections. The hardware works without our cloud — detection and counting run on the device. And we intend to publish enough of the protocol that an installed unit could be maintained even if we vanished. We're not building a roach motel.

Is it approved? Do I need a permit?

A physical control device that emits no substance shouldn't fall under the APVMA's agvet chemical registration regime — the Agvet Code is written around substances, and thermal varroa devices are already sold in Australia without registration. But we're seeking written confirmation from the APVMA rather than assuming, and we'll publish what they say. Varroa remains notifiable in every state and nothing about this device changes your reporting obligations.

When can I buy one?

We're not taking orders and we won't until there's independent efficacy data. The realistic sequence is: engineered prototype, supervised trials across two seasons with named commercial beekeepers, a published study, and then a product. If you'd like to be part of the trials, the form above is the fastest route.
