🧵 Directed energy weapons against mosquitoes

There is plenty of use for those both in the industry and the army.
Why is there no such device on the market against mosquitoes? Wouldn't it make sense to invent one using already known theory of electromagnetism.
There are a few interesting solutions to them like mosquito laser or even your regular led traps

god please yes I want to murder mosquitoes with LASERS

The picture might be misleading but I thought about something like millimeter wave directed energy or a heat wave.
Think about an open area like a park with those pests flying around, it would make sense to use something like that, and it also wouldn't disturb the local ecosystem since they won't be actually killed

Now from my limited understanding of physics and common knowledge low frequency sounds don't actually do anything to them, so why not heat up and penetrate their skin at a small enough depth and create a similar effect to millimeter-wave weapons that affect humans but fine tuned to them only, is that feasible?

Looks like there's one under development:

Also there's obvious safety risks. Computer vision models are not perfectly accurate. A sufficiently powerful laser could blind someone or burn the skin.
That said you could probably build a system with a raspberry pi, 2W near-infrared laser, actuators, HD camera, etc. Would probably be buggy tho ;)

Just drink vinegar. It comes out in your sweat and repels mosquitoes

Well I want to make money not to solve a personal problem duhhh

there's a salt gun for flies so why not a laser gun for mosquitos?

I thought about an area capturing mosquito deterrence

If it could kill a mosquito, it could certainly blind you, I suppose even seeing the mosquito getting burned would be dangerous.

Again I'm talking millimeter waves, not lasers exactly

Do you have any idea how much that would cost at those power levels? You can't even get more than a few watts out of a solid state amplifier in that frequency range, plus there aren't any unlicensed bands so the FCC probably wouldn't even let you use a device like that.

Active denial systems, there definitely should be something not too costly or restricted for commercial or personal use.

Yes, and that currently costs millions of dollars per device. You will not find a company selling TWTs or Gyrotrons in that operating regime for less than a few hundred thousand.
It's not a cost effective way to deal with bugs.

What about low cost twts as proposed in this article?

But I am not sure they are available..

already exists
mosqitoes and flies see their reflection (directed EM wave), get scared and fly away

Yes, you can do that cheaply at S-band, but scaling it to higher frequencies is difficult. The SWS needs to be smaller which makes it harder to manufacture and has to deal with an increased thermal loading. Since the interaction region is smaller, that means you also have a smaller electron beam, which needs a much higher current density to still get decent power. So you need a much better cathode and electron gun than that design, probably involving more expensive emitter materials and tighter machining tolerances. Plus stronger magnets are needed to keep the beam focused and not hitting the SWS.
You also can't operate CW or the tube will melt, so you need a good pulse modulator which even if you built yourself would cost ~$1000 just for the capacitor.

>but fine tuned to them only
Nah I don't think that's possible. Will always be some sort of risk that one of your desktop death stars ends up crippling someone's eye.
