I think the weirdest way I killed a bug was by pointing it out to my cats.
They did the rest.

They don't do that anymore.

Oh oh, wait. One time there was a spider on the ceiling so I used a squirt gun to get it down then just squished it. xDD

I've never really killed any bugs in a weird way before. I always kill the big ones with a shoe or a flyswatter XP My friend brother used to pull the antennae and tongues off of butterflies tho :'( It was cruel and we hated him for it T_T
