A couple of years ago, I rented a house from some friends that was INFESTED with roaches. Imagine waking up at 2am because a roach crawled between your neck and the pillow! Back then, I killed them where I found them. I would be up at midnight doing some kind of Mexican hat dance on the patio, sometimes killing 20 in one session. I had glue traps and Raid everywhere in the house. By the time I moved out, that place was roach-free. Since then, I've had a hard time even seeing roaches without it turning into some kind of nightmare that night.
Do you have any food limitations (allergies, digestion issues, et cetera)?
