The average pest control service should only be needed every 60-90 days when it comes to general pest control. If it is an active infestation of roaches, you would want to do treatments 2 weeks apart until you no longer see them, usually about 2-3 treatments. With bedbugs, it’s 3–4 weeks apart and typically takes 2-3 treatments to eliminate. 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.
