Bonide Boric Acid Roach Powder is not mixed with water. It is applied dry to voids and cracks and crevices.
It is important to understand that Bonide Boric Acid Roach Powder is only going to work on those roaches that actually come into contact with it. The majority of roaches live in cracks, crevices, and wall voids and only come out when absolutely necessary. Bonide Boric Acid Roach Powder has nothing in it to actually attract the roaches so it must be strategically placed into the places where roaches live and it takes several days for the roaches to actually die after they ingest the dust, during which time they can continue to breed. We recommend using a roach bait gel, an insect growth regulator, and an insecticide spray for faster results. Please check out our Roach Control Kits. The kits come with all of the components you need to control a roach infestation quickly.
Bonide Boric Acid Roach Powder should not be applied around any edible vegetation. We do not recommend consuming any of the vegetables that were treated.
