Glad you mentioned about the spark plug wire. My sister had squirrels eating the insulation under her hood. They even got to the ignition wires but we were able to fix that. Been all over the web about how to keep squirrels from doing this but found little useful info. I used a spray from a lawn and garden place to try and keep them away from my Christmas lights but it smelled bad and didn't do much good so I don't think it would help with a car. Anybody have a way to keep squirrels out of the engine ?
Squirrels do pretty much whatever they please. We have them in abundance in my neighborhood and I used to hand feed cookies to the little democrat beggars. Not any more.
Last spring they ripped up some fairly expensive patio furniture to build their little nests with, I assume, or maybe just because the vandals knew they could.
I live in town and shot gun blasts would draw unwanted attention or I'd relieve myself of my squirrel burden.
