But wasps are naturally aggressive, aren't they?
I meet one fucking scary hornet one day. It looked like a toy robot because of its red eyes. Killing them with electric flyswatter takes a lot of time and it looks like a bug abuse (poor stupid hornet, but they just got lost).
Even using the highly amplified one. This bugger seems to home at heat sources, striking light sources, my PC, and everything that emits heat. It produce quite a noise, so I decided to end its suffering before something broke or gets allergy reaction. Squished it flat.
