Wasp sprayer drone

There doesn't seem to be much in the domestic market, however.

Until now ...

BorgCo engineeering is developing a consumer-grade drone capable of dealing with those little black-and-yellow flying stinging bastards on their own terms.

The system consists of a large R/C camera drone with FPV control. Slung under the drone is an aluminium spraycan with a solenoid valve. A plastic pipe carries the nozzle well clear of the rotor downwash, into the field of view of the camera. A pair of converging lasers mounted on each side of the drone allow the pilot to accurately judge the range-to-target and aiming point of the sprayer.

The right-hand laser is green, the left-hand is red. Thus as the drone approaches the target, the green dot is on the right of the image. If the two dots cross over, you're too close ...

Now, it doesn't matter if the evil vermin have insinuated themselves into the eves of your dwellng, or right at the back of your garage. You can go in there and poison the lot of 'em with no risk of being stung. No ladders, no protective equipment, no risk of stings. Just lots of lovely little twitching tabby corpses.

The design also allows the deployment of much more toxic biocides than can be safely used by the average householder - for example, cyanide-based agents, derivatives of short-chain fluorophosphonyl alcohols, and chlorine trifluoride.

Canisters containing fast-drying opaque paint, or HF, are available for those with a dislike of CCTV cameras.
