How to keeps squirrels out from inside your car hood:

Another viewer, Karen L. from Middleton, Wisconsin, wrote, "I was wondering if you know the best way to keep squirrels from getting into my car and eating the wires and nesting by the engine." Karen has already tried moth balls and wants to know what else Lou would recommend.

Lou said that hanging a rodent repellent inside the engine compartment should do the trick.

  • Bonide 865 4 Count Mouse Repellent, $7, Amazon

This repellent emits an odor that keeps the rats and squirrels away, but is not offensive to humans or pets.

  • Fresh Cab Botanical Rodent Repellent, $14 (usually $20), Amazon

For infected areas, the manufacturer advises using one pouch per 8 square feet of floor space and replacing it every 30 days.
