First determine how raccoons get into your attic and remove any loopholes. It may be a hole in the roof, open windows or dog doors. Those raccoons who are already run through the attic will be scared by electronic repellers or motion sensor lamps, such as Motion Sensor LED Porch. You can also use safe live-catch traps (you mustn’t kill raccoons, it is forbidden in many states!), And then let them out of the house.
