Can mice chew through a vehicle bag?
They can chew through almost anything. Since they can not smell or see anything in the bag there is no reason for them to do it. We do get several reports a year about a mouse building a nest underneath and then chewing around the nest area, putting holes in the bottom of the bag. Usually they don?t bother the vehicle, but it has happened. The vehicle bag is probably the most effective deterrent to mice available, 98% effective, but not 100%.
