Wildlife Burrows

Several wildlife species will burrow under buildings, porches or decks. Large burrow holes (four inches or more in diameter) are typically made or used skunks or foxes. Coyotes, badgers and woodchucks (also known as groundhogs) also dig and use larger burrows, but the burrow hole tends to be larger (10 to 14 inches in diameter). Muskrat, mink and weasel burrows tend to be near water.

Smaller burrows (three inches or less in diameter) are usually made by chipmunks, thirteen-lined ground squirrels, voles, crayfish or snakes. Small holes outside the home near foundations or under sidewalks are often used by chipmunks. Thirteen-lined ground squirrels make multiple burrow entrances and prefer areas of short grass. Crayfish holes will be found near water and look like a small tube of mud with a hole in the middle.

If you have seen the animal at the burrow and know which species it is, the Wildlife Identification Mammals pages provide wildlife damage prevention and control methods for each species. If you aren’t sure what species is using the burrow, the Burrows & Dens pages provide photos to assist in identification.
