hey, if you live in a part of the country where your gto is tucked away for the winter avoiding nasty roads and destructive salt, you have to declare war with unwanted rodents. in the northeast those little bastards are relentless at making a winter nest out of your car. i use SCENTED dryer sheets , and lots of them everywhere. under the seats, stuffed in heater ducts, fresh air vents, trunk, and even under the hood. valley pan, battery, blower cover on firewall, everywhere. i assume they dont like the perfume smell they omit, but for whatever reason they work well. i also set a couple of old style wood snap traps on garage floor just in case they get near my car. rickm.
