Do Rats Dig Holes in the Ground?
Moist garden soil is one of the rats' preferred burrowing locations. A new burrow may have a fan of soil next to the hole. The dirt displaced by the rat digging is usually up to 1 inch tall. Rats dig holes at night, so you might not see them moving in. To check if a rat hole is in use, put a wad of paper in it. In fair weather, a rat will move the paper out of the way within two days if it's an active burrow.
