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.
Notice the crescent shape with the plug, unlike a mole mound that is conical shaped and never has a plug. Two gopher mounds, but still the crescent with the plug. In addition to creating mounds and eating roots from underground, gophers will dig open holes to the surface to feed on surface vegetation.Some feed holes are only the size of a silver dollar, other feed holes are 2 to 3-inches across.ophers are active year round, solitary and territorial. An adult male gopher can control territory up to 2000 square feet. A gopher will dig up to 7 or 8 tunnels which may extend as much 800 feet each.
