Read the entire label and only use insecticides according to label instructions. Most homeowner products come in a dust, bait or spray form. Boric acid is probably the most commonly used dust labeled for cockroach control. It should not be applied in open areas such as on shelves and counters where food and utensils are kept. Never place in reach of children and pets.
Baits usually come in plastic stations or in a gel tube.
They are effective in many indoor areas, especially in the kitchen. Some of the commonly used insecticides in baits include hydramethylnon, sulfluramid and avermectin. Bait stations are most effective placed in corners near where you suspect cockroaches are hiding or coming into your home. If you are having trouble with the large outdoor cockroaches, get the larger bait stations since the adults cannot fit into the smaller ones. Bait gel should be placed in cracks and crevices where cockroaches hide.
