Dragon asks a good question, how many roaches until you "have roaches?"
I see maybe 5-6 roaches a year in my apartment. I'd say i don't have roaches.
Taj mentions, "a roach or two every few days." I'd say that's definitely having roaches.
I think I'd settle for a roach or two a month means you got them. So let's call it at ten a year or less, and you get roach-free certification.
Girls could definitely start checking if your roach-free certification card is current. Which means some guys are gonna have to borrow their boys' card, cause their crib is straight infested. On some don't even turn on the lights after sunset ish.
10 or less and you are roach-free certified. Yes?
