I been there dun dat. with 2 different cars in the past 2 years. 06 Chrysler product whe the 5.7 hemi. Car is in the carport alone for only 3 days... I fire it up. Missing like crazy. Pull the engine cover... the wireing harness for the ignition chewed in severl plces.. apparently in their wisdom to be enviromentallly friendly they made them with a soy based insulation. Rats LOVE it. So spend a lot of trime soldering new wire in place, somebody suggested peppermint oil. Smells great but within a week I detect them back in there... Moth balls in a sock... Lasted only a few days as well. Same with Cayanne. At the local garden/farm store in their poison closet..... a spray can of rodent and pest repellant. ... No smell I could detect and it has been good for about a month now. I also found that in our collector car;.... I just leave the hood open. they dont seem to bother with it when open and exposed. I do not like nor do I suggest any kinds of poison. Here we have several predictors for mice and rats, cats, and Owls who almost rely on mice and rats, and then Eagles, Ravins, crows and other raptors.
