Roof Rat

Droppings

Droppings are the most commonly encountered evidence of rodent activity. Even a small rat infestation can produce literally thousands of droppings in a short period of time.

An adult rat typically produces 40 to 50 droppings per day. These fecal pellets are usually dark-colored, ½ inch in length, and pointed at both ends.

Gnaw Marks

Evidence of recent gnawing is an excellent sign for determining the presence of Roof Rats.

Rats tend to gnaw on wooden structures such as corners, floor joists, and wall studs. When Roof Rats gnaw holes into cartons and boxes, the holes typically measure about 2 inches in diameter and contain rough, torn edges.

Sounds & Odors

Another indication that rats are present is a strong musty odor. Cats and dogs may sniff excitedly and probe an area where rats or mice are present and will often indicate this by scratching or making unusual sounds.
