How would あなた kill a cockroach?

I use a serviette and take him and bring in out of the house.

Survivence: 50% (If あなた dont press too hard)

Put them in my pants. They'll die. Eventually.

lol kidding... Nuclear bomb and dynamite, または mix bleach, vinegar, window cleaner, weed killer and drain cleaner together and spray them...

...Why am I so crazy today:/

have someone else kill it
*wipes hands*
problem solved

Why do u need to kill a cockroach

pick it up and find a クモ, スパイダー to give it to, preferably out side and not picking it up with you're hands

I would just grab whatever is around me and crush it.

I don't kill cockroaches (intentionally または on purpose).
They deserve to live their life to the full extent as much as we do.

throw my cat at them

I usually just like trap it under something until someone gets it.

tear off his wings a kick it out of my house and slice off his butt..

get up my bro shoe (not my own) and スマック that cockroach on the back and somehow get dispose of him!
