Electronic mosquito swatter-Mosquito Zapper!
I like this tennis racket looking thing that kills insects for you. Basically all you have to do is to swerve it at the bug / insect and ZAP, it will instantly kill them using high voltage. There is an ON / OFF switch for protection from zapping yourself. It is very portable and a good thing to have when doing outdoor activities such as camping, hiking, fishing etc. Requires two AA batteries.
