happy birthday to me

i just woke up (too rare of an occurrence) to find a bug on my arm. i instinctively moved into the light, but then thought it might be better not to see exactly what it was (let's say it was definitely bigger than a ladybug) and kind of flung it off. sam played with it for a good 20 minutes - i have the cat with no killer instinct - before depositing it on the couch where i saw it was indeed a 1 inch+ roach. maybe i do want a roach bomb afterall. are they super effective? like guaranteed? for how long before they infest my apartment again via my neighbor's? i am sooooo beyond grossed out. not to mention wide awake and itchy feeling.
