Rats are rodents that can spread disease, contaminate food and chew up property. Rats burrow in the ground, forming tunnels with one main opening and one or two exits. The 2- to 3-inch wide entrance hole is usually found under a covering like a low plant, mulch or debris. Before closing up burrows, the rats must be eliminated or they will just re-open the holes.
Rats often nest in gardens and yards, especially if there is plenty to eat like fruits, vegetables and composted meats. It is essential that you get rid of the rats before they take haven in your home; however, in the meantime, make sure you have covered any holes or possible entrance ways into your home.
