The average pest control service should only be needed every 60-90 days in general. If it is an active infestation of roaches, you would want to do treatments 2 weeks apart until you no longer see them. It usually takes about 2-3 treatments. With bed bugs, it’s 3–4 weeks apart and typically takes 2-3 treatments to eliminate them. In the case of bedbugs, we usually recommend treating the whole house and not just one room. Even if travel brought them home, we may do pest control on the car.
