In addition to following the tips in the attached checklist, you can buy pesticide sprays, dusts, baits, and traps that will help you control cockroaches. Buy a pesticide only if it is in the original manufacturer's container. Make sure the container has a label that lists the pesticide's chemical name and ingredients, and directions for use. The label should say the pesticide is for cockroach control. You can also buy concentrated pesticides that need to be mixed with water before you spray them and baits may also be used.
Baits are low risk pesticides and work well for cockroach control.
Bait can be carried inside walls and hiding places used by the cockroaches. If you use cockroach bait, do not use a spray in the same area since the spray may repel the cockroaches and prevent the bait from doing its job. Boric acid and other pesticides should be used only according to the label's instructions. Do not use boric acid for cockroach control if the container does not say it can be used for cockroach control. Never buy pesticides at a flea market or from someone selling out of a car.
