I was told that people who have boats use the Bounce Dryer Sheets all around their cushions and bed mattress for spiders. (They have huge spiders) Does anyone ever spray their camper with an insecticide for spiders? I am currently in the process of spraying our house and wondered should I just spray the outside of the pop-up too. I also read on this forum that if your using dryer sheets for mice control you have to change them every 45 days. Does anyone really pop open their camper in the middle of winter to do this?
