We have roaches everywhere! We have bombed, done boric acid, bait traps, gel, sprayed, even hired a professional. The professional said it's because they have been here so long and have nested into the walls. We have lived here a year, and I can't stand them!!!! We keep a clean house, Absolutely no dirty dishes on the sink and I sweep and mop before bed almost every night and I'm clueless what else to do because we can't afford to move again and the landlord won't pay for anymore poison or cover costs of us moving to a different house.
