Rodents can cause a plethora of problems with your vehicle. They chew on wires causing electric issues and possible engine fires, make nests on your engine and in the air box, and pieces of their nest can be sucked into moving parts on your engine (we saw a failed alternator with insulation sucked inside of it last month!). Rodents move into engine compartments because they are dry, warm and cozy – plus lots of material they can use for nests. Always keep an eye out for rodent activity, and clean out any nests you may find. You can also place dryer sheets in the engine compartment – they hate the smell! Make sure to place them away from any parts that move or get hot (between the battery and firewall is a good place on most vehicles).
