It cost us $800 in re-wiring our truck in Scottsdale Arizona last year due to mice/rat/rodent/whatever infestation. The truck wasn't being driven on a regular basis so the packrats moved in. I learned that some of the wiring in trucks are covered in what I thought was a petroleum-based rubber. WRONG. Some are made with small amounts of PEANUT OIL! Delicious for the packrats. So a word of caution if you leave a vehicle undriven for long periods of time...well, don't.
Also, if you do find a nest, but sure to have everything under the hood power washed to remove and scent the rodents left behind. That scent will bring them, and their buddies, back.
