Roaches are living under my counter and on top of my dishwasher.
It is important to understand that a product like boric acid or diatomaceous earth are only going to work on those roaches that actually come into contact with them. The majority of roaches live in cracks, crevices, and wall voids, and will only come out when absolutely necessary. Boric acid and DE have nothing in them to actually attract the roaches, so they must be strategically placed into the places where roaches live, and it will take several days for the roaches to actually die after they ingest these types of products. During this time they can continue to breed. We would recommend using a roach bait gel, an insect growth regulator, and an insecticide spray for faster results. You may want to take a look at our Roach Control Kits, which contain all of these products.
