Q.We have a couple of openings in the ground right next to our patio. We live in the city and I know there are rats around. Could these be rat holes?
The rat burrow itself rarely goes farther down in the ground than 18 inches but can be much deeper when rats are trying to dig under foundations. Burrows are usually less than 3 feet long with a central nest area filled with leaves, grass, or soft debris.
