I have around 20 vents on my roof and I currently do not have a roof rat problem but I want to cover them with something to prevent roof rats getting into the attic. I'm sure I can find something at home depot that will do this and still allow the air passage through the netting/mesh that I put over the vents.
My question is about the vent that is used for the dryer. Lint coming out of that vent can attach itself to the covering and create a fire hazard. Is there a safe way to prevent rats from getting into the dryer through this vent?
