A: The services of a pest control operator are necessary to obtain satisfactory cockroach control since the general public cannot purchase effective insecticide formulations. Successful control involves a cooperative project between the pest control operator and the people experiencing a cockroach problem. A complete and persistent sanitation program conducted in the roach infested area will go a long way towards reducing cockroach populations.
Some suggested sanitary programs include, removing garbage daily from your home, promptly cleaning up food debris, and storing food in tightly sealed containers. It is also important to seal any openings around baseboard and pipes and windowsills and foundation structures because cockroaches may enter your living space through these openings.
