Over-the-counter pesticides can be counterproductive in cockroach control. Often the bugs will run and hide when household "bombs" are used, causing the roaches to harbor in unusual places and making them harder to reach. They can, however, be controlled and eliminated using a combination of good housekeeping, preparation, and the appropriate application of chemicals labeled for use against cockroaches. Pesticides and their application are regulated by the Environmental Protection Agency of the Federal Government. No pesticide may be applied in a food handling area that will contaminate food or utensils (pots, pans, glasses, plates, forks, etc.) that come in contact with food. Those items must be removed and covered. There is no exception to this law. The most common type of cockroach in San Diego is the German cockroach.

Cockroach control may take three weeks after the time of service. Please call our office for a follow-up appointment if you still see live roaches three weeks after your initial service.
