Other Names: Black Rat, Fruit Rat, Ship Rat, Alexandrian Rat
If there is plenty of food and shelter, Roof Rats will gladly live in close proximity to humans, particularly in attics, ceilings, or wall areas. Roof rats inhabiting upper areas of buildings or homes often gnaw on wires found there, possibly leading to fires, outages, and production down-time.
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.
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.
