Signs of an Infestation

There are many key indicators of a roof rat infestation in the home. First and foremost, seeing an actual rodent, dead or alive, is a telltale sign of a potential roof rat problem. Another common sign of a roof rat infestation is the presence of droppings around the home. Fresh roof rat droppings are soft and moist, whereas old droppings are hard and dried. The droppings usually measure about  12-13 mm and have pointed ends. Droppings from Norway rats are larger – measuring about 18-20 mm with blunt ends. The discovery of gnaw marks, damaged goods, nests or greasy rub marks also indicates roof rat activity. Other common signs of an infestation are noises in the attic or house walls and damaged electrical wires.

How to Get Rid of Roof Rats

To prevent a roof rat infestation, seal up any holes or cracks larger than a quarter with silicone caulk and be sure that all windows and vents are screened. Keep trees and shrubs trimmed away from the building and cut back limbs overhanging the roof. Roof rats are drawn to any accessible food sources, so clean up fruit that may fall from trees in the yard and keep garbage in tightly covered receptacles. Be sure to also store pet food and other dry food in sealed containers. Additionally, eliminate any outdoor sources of water such as leaky sprinkler heads, pet water dishes and birdbaths.
