Another satisfied customer of boric acid.

Viewed a flat on a Sunday, went ahead and rented it. Realized after moving in that all the sandwich shops serving the nearby uni Monday-Friday drew an ungodly amount of cockroaches. I hated getting up for a glass of water in the middle of the night because I knew the horror show I’d see upon entering the kitchen after dark.

Roach traps didn’t make a dent, and we had two cats so didn’t want to go in for heavy duty poisons.

Read about boric acid in a Metafilter post, spread some along the usual scurrying areas and… wow! Barely saw one ever again.
