Mice in Class C GM van chassis heater

Bought a new Coachmen Leprechaun 260DS in 2015, first winter had it stored in a farm out building, when it came out of storage found mouse nests and had to replace one of the fabric sun visors in the van front and the memory foam cover on the rear bed. So this last winter bought a cover and stored it outside at home in the driveway. Checked the inside everyday and caught some mice in spring traps early last fall, always in the van front. Noticed mouse droppings on the floor by the heater vent so plugged the main vent inside with steel wool and noticed the steel wool had been chewed from inside the vent.

The fresh air intake for the heater air conditioner is a slotted plastic cover under the wiper arms and the cover can be removed after the wiper arms are pulled, bought a wiper arm puller tool on e-bay. Pulled the wiper arms and removed the plastic cover, is two pieces held with a snap connector on each end and some screws. Its an open freeway under the cover into the blower motor, there is no screen to block the mice.

The plastic cover has some narrow slots for air intake but large enough openings on each of the wiper arms for mice to crawl in or out. Early this spring put some aluminum screen, comes in a roll, usually used to block debris in rain gutters all the way under the vent panel and screwed it back down. Still have traps in the front but appears to be where the mice have been getting in as having caught nothing since the screen went in.

We lived in the country and on-going mouse problems. Found that the old fashioned mothballs, the ones that smelled, seemed to keep them out. Also our local ACE hardware store had synthetic predator urine for repelling rodents, bobcat, fox and coyote. I know what you thinking, this stuff will smell worse than the mice! But it doesn't have much smell.

Mothballs don't deter mice, neighbor has a diesel pusher and the mice used the mothballs as part of the nesting material. Another tip Irish Spring soap does not work other than to attract mice, used it the first winter in the farm building storage, the two bars under the hood were almost completely gone, bars on the inside were partially eaten, mice eat soap no matter what the flavor. If there is a way in they will find it.

One word: Cats!

Well moth balls worked for me, my direct experience. They have to be the original type that smelled of naphtha, not the ones you get in most places now days that have no odor. I agree that Irish Spring soap does not work, I tried that and the mice ate it.
