I dun like to kill roaches, it gets pretty messy. If you spray
em with insecticide, you also become what he americans like to
say... "collatoral damage" ie, you also have to breath in the
insecticide and you become "collatoral damage". If you smack them
roaches with somethin, them roaches will burst its' innards and
spill them guts and gore onto your floor, wall or where ever you
smack em dead. Its' guts and gore will leave a disgusting smell and
you have to scoop em and clean em up!! 
Yesterday, I caught one baby roach, it was clinging onto the
curtains and this morning I caught one adult roach in the kitchen.
I put on a transparent plastic bag, use it as a glove and with one
swift move, grap and bag them roaches. It's still alive and kickin.
Then I just toss them roaches out into them bin outside...No messy
stuff left by them roaches nor do I have to become "collatoral
damage". I also caught a spidey hanging down from the
ceiling.....just hook my finger onto it's web and let it loose to
crawl onto the plants outside the house.
