how to keep squirrels from chewing christmas lights

Squirrels love chewing on things, especially in the winter when they're trying to stock up for the long winter. So, to keep them from chewing on your Christmas lights, try these tips: 1. Use a thick cord. Squirrels are more likely to chew through a thin cord than a thick one, so using a cord that is 1/2 inch thick or more is a good way to deter them. 2. Cover the cord with something they won't like to chew on, like a wire mesh or burlap.
