I have only used two things that aren't so poisonous to treat my houses for roaches (that flat worked!) that were not hard on pets. Years ago in Galveston, which had roaches pretty bad, I used little foil cups of powdered boric acid. Mind you, I only placed them behind and underneath heavy furniture like hutches, sofas, dressers and such where the dachshunds couldn't get. I also went out of my way to empty all kitchen cabinets, lower cupboards and (using a spoon) tipped a thin line of the stuff around the cabinet perimeter seams (side and back seams). Roaches tend to travel/walk along perimeters. When they walk through the stuff, doing what roaches do, lick their hairy legs/feet all the time, they eat it and die. They also carry it back into the wall nests for the rest of the little buggers to get it on their legs, too. Job done. I never had roaches again in 10 years before we moved. BTW, one of my dachsies actually reached one of my foil cups and ate a small amount of the boric acid before I caught her and she did NOT have any issues from it.
Second foolproof roach method was used at my current house we bought 4 years ago. Back yard was infested with fleas (not roaches) but in Texas, we have the occasional roach get inside the house. To kill the fleas mainly, I dusted out pool filter diatomacsous earth (use food-grade for this, available in garden centers). I dusted every square inch of the back yard, all surfaces (bare dirt areas, cement paths, flower beds, house perimeter, driveway). Use on a dry day as it loses strength if wet or it rains! It's ground up crustacean shells. It scratches/scores the insects exoskeletons and they basically dehydrate and die. Haven't had a flea bite on the dog (or us) in 4 years now! Side benefit, when a roach finds its way into the house, I find them "belly up" in various stages of slow death......and I don't have to lift a finger! I perversely enjoy this side benefit of DE because I cannot abide roaches.
Either method DOES work even if the infestation is bad!
