Can flies recognize that I'm holding a flyswatter?

Has this ever happened to you? There's a fly in the house, buzzing around you, so you go to the cabinet to get the swatter. But as soon as you start wielding it, the little bastard disappears. You set it down, and now he's back, taunting you.

Ok so obviously flies don't taunt, but do they have the capacity to recognize, even instinctually, that I'm holding a deadly weapon?

We have 2 advantages: we can build tools for specialized purposes, like killing flies. We can analyze misses and predict where a fly will be when it tries to evade a strike.

How the fuck have we not got wee mini computer controlled lasers yet that take them out like a micro size star wars thingy

Because software is very brittle these days, it would occasionally perform surprise lasik on your guests.

Someone did build an automated laser roach killing device once. Though I think it was fairly short range or had some caveat like that.

IIRC there's a YouTube video of it somewhere.
