How to Keep Ground Squirrels From Burrowing Under the Foundation of a House
- 1). Dig a trench 1 foot wide and at least 1 foot deep around the outside of your house. A deeper trench may be needed because chipmunks, for instance may burrow 2 or 3 feet down.
- 2). Bend the wire mesh into the trench so that it runs down the side of the trench next to the house and then across the bottom in an L shape. Larger sizes of wire mesh will keep out squirrels but one advantage of using a 1-inch or ½-inch size is that it also keeps out smaller rodents such as mice, voles and rats.
- 3). Fill the trench in and tread the soil down firmly.
- 4). Remove grass and weeds as they grow back over the trench to make the border around your house less appealing to squirrels. Paving or gravel makes a permanent, squirrel-unfriendly border.
