Hey everyone, welcome back to The Lenz Podcast! Episode 3, February 24th, 2026. I’m Alex, that’s Maya, and today we’re asking a question that sounds like it came straight out of a sci-fi movie — can honeybees actually be trained to sniff out buried landmines? Maya’s gonna argue yes, I’m taking the skeptic’s chair. Let’s get into it.
MAYA
Okay so this isn’t even fringe science. DARPA funded research on this. The University of Montana worked with Sandia National Laboratories, and in 2003 field tests they hit a 98% success rate — bees hovering over buried explosives, responding to chemical vapors leaking through the soil.
ALEX
Hold on — 98%? That number comes from Guinness World Records, Maya. That’s a record-keeping outlet, not a peer-reviewed methods paper.
MAYA
Fair, but the research behind it is documented in peer-reviewed journals. There’s a paper in Science of the Total Environment describing a full biohybrid system using honeybees for landmine detection. And SPIE Proceedings published work on the DARPA-funded training and deployment program. These aren’t blog posts.
ALEX
But here’s my issue — if you actually read those technical sources carefully, they describe passive sampling. Like, analyzing what bees bring back to the hive. That’s different from bees actively finding mines in a field.
MAYA
That’s only half the picture though! The St Andrews repository paper explicitly says the system uses — and I’m quoting — ‘two complementary landmine detection methods: passive sampling AND active search.’ You’re cherry-picking one method and ignoring the other.
ALEX
Okay but even the Sandia press release uses words like ‘if’ and ‘may’ — that’s conditional language, not proven capability.
MAYA
That’s because it was a news release about ongoing work! The actual field results tell a different story. James Madison University’s CISR Journal confirmed that ten full-size colonies were conditioned to search for explosive vapors and tested to see if they could locate them. And they did.
ALEX
But that same JMU review warns that many popular reports about bees detecting landmines are inaccurate and could mislead people into selling services they don’t understand.
MAYA
Right — and that’s a warning about commercial misapplication, not about whether the science works. You’re conflating bad business practices with the underlying research. Los Alamos National Laboratory trained bees to respond to TNT, C4, and TATP using classical conditioning. That’s three different explosive compounds, independently verified.
ALEX
I mean… that is a lot of independent verification.
MAYA
And there’s the Croatia work too! In 2017, they used trained honeybees to find missing landmines from the Croatian War of Independence. Professor Nikola Kezic at Zagreb literally demonstrated conditioning bees on TNT scent with sugar solution rewards. Reuters filmed it.
ALEX
Wait, really? They actually deployed this operationally?
MAYA
Yep. The claim says bees ‘can be trained’ to detect landmines. Not that it’s a perfect operational system — just that the capability exists. And between DARPA funding, government lab results, peer-reviewed papers, and actual field deployments, that’s pretty overwhelmingly established.
ALEX
Hmm… okay, I’ll be honest. My strongest argument was that the technical sources were more cautious than the headlines, and that’s true. But you’re right — the claim is about capability, and the evidence from multiple independent institutions is hard to argue with. I was stretching.
MAYA
Ha! I appreciate the honesty. It’s a wild fact, but it’s a real one.
ALEX
It really is wild. Alright folks, we’re calling this one True. Honeybees can be trained to detect landmines — backed by peer-reviewed research, government labs, and field tests. Nature’s tiny bomb squad. Thanks for listening, and we’ll catch you next week on The Lenz Podcast!
