If drawers are cleaned thor- oughly, it is not necessary to spray inside them; it will help to spray the sides, backs, and under- surfaces. Resistance of Cockroaches to Insecticides In areas where the German cockroach has developed resis- tance to some insecticides, poor control of affected infestations may become evident. German cockroaches can be controlled, however, with the proper use of approved insecticides. Frequently, poor control of cockroach infes- tations is due to improper use of insecticides and lack of good sani- tation practices in infested envi- ronments. OTHER METHODS OF CONTROL Registered baits containing ap- proved materials may be used in cockroach control programs. Buy these baits and place them in areas frequented by cockroaches. Do not use them where they can be reached by children or pets. Fumigation Fumigation immediately de- stroys a cockroach infestation, but it is dangerous in congested or commercial areas, and it is expen- sive. Buildings in such areas are likely to become reinfested within a short time. 8.
