Trip report: the experiment was a RESOUNDING success! Using my toddler as experimental bait, we walked through swamp and marshland, with a ton of still rain puddles. Picardin applied in strategic locations resulted in nearly a 100% prevention rate Only one got to him, at the end 
Image from X post Quoted post by kache (@yacineMTB) Wish me luck. I'm about to venture into the most mosquito infested area I know to get some videos of some turtles. I hope my new defenses that my ais and myself came up with actually work this time (tight weave clothes and picardin) Open quoted post on X

The one that got him in the end was on his hand which I purposely did not apply the picardin on because you know how toddlers are with her hands in their mouths

A lot of interesting observations. We got swarmed probably by 3:00 or so mosquitoes every three meters of walking and I was walking quite quickly. The effect of picardan seems to only really be effective while they're flying. They just veer off course

It's almost as if they have internal accelerometers that get completely zapped as soon as they get a wiff of the stuff

One thing that I think helped both of us a lot was the fact that we had a stroller and because I had some Picard and strategically applied on landing spots on that stroller when they would take off again to find a proper biting spot they would pretty much immediately veer off course

I was quite surprised to see how easy the mosquitoes were to detect as they approached the stroller. It's almost as if they maintain speed in a preliminary phase to attempt to landing on a good spot. I wonder if the heuristics they use are abusable

Seeing how effective the picardan was at interrupting their flight and their approaxh and how slow they are, it makes me realize that a tf2 engineer turret type solution would work quite well for them

Probably something that resembles a miniature shotgun. Some benign chemical that makes your wings sticky in a spray on a camera gimbal

Today during toddler nap time I will have to finish my stereoscopic global shutter camera raspberry Pi AI solution as well as create a simple test harness to see how well it does detection at different focal lengths and lighting conditions. I'm basically going to hang a tiny bead from a thread

One thing that would be ideal is having this entire camera array actually be part of the gimbal as well as the fan / air pressure /shot gun / soaper

I'm sick in the head
Explanation
What it says A field test of mosquito defenses in extremely mosquito-heavy swamp/marsh terrain. The author reports that strategically applied picaridin plus tight-weave clothing prevented nearly all bites on his toddler; the lone bite was on an untreated hand. He observed mosquitoes repeatedly veering away after approaching picaridin-treated surfaces, including the stroller.
The thread then turns into an engineering idea: exploit mosquitoes’ apparently slow, predictable approach behavior with a stereoscopic/global-shutter camera system, Raspberry Pi detection, and a gimballed device that could disrupt them using air, spray, soap, or another benign mechanism. He proposes testing detection across focal lengths and lighting using a suspended bead as a target.
Context This is anecdotal experimentation, not a controlled efficacy test. The author’s speculation that picaridin disrupts mosquitoes’ “internal accelerometers” is explicitly observational inference, not an established mechanism.
Why it matters The interesting idea is broader than “picaridin works”: mosquito interception may be an engineering/computer-vision problem because their terminal approach appears detectable and mechanically disruptable. The thread sketches a plausible path from passive chemical repellence toward active, targeted mosquito defense.
