Rodents nest in many different places in cars (and campers and trucks), which is a potential risk to anyone who uses the vehicle. They are more likely to nest in cars that aren’t used very often, but they can get inside any vehicle. Nests could be anywhere in the engine compartment, including in the area under the windshield wipers, between the battery and the frame, the engine air filter and near or in filter hoses and ducts of the vehicle’s passenger compartment air intake system (ventilation, heating and air conditioning), including the cabin compartment air filter. In other areas of the car, rodents may nest in the trunk and inside the spare tire compartment, throughout the passenger compartment, and inside the tailgate and headlight enclosures. Rodents get in through rust holes, vents, and ducting.
