My parents have a squirrel problem. The squirrels eat through the wires in their cars, get into the house and chew through things, etc.
What can be done to prevent them from destroying the property?
They don’t want to get a dog or a cat, which seems like the best solution.
They tried buying plastic owls and using them to scare the squirrels off. That didn’t work.
What other options are there? is there some kind of spray you can use the same way we have sprays for the perimeter of your house that keep insects out?
