What do roof rats look like?

Adult roof rats have smooth dark brown or black fur with a white, gray, or black underbelly. They have pointy noses, large dark eyes, and large ears that are almost completely devoid of fur.  Their bodies are about 6 to 8 inches in length from head to rump and their scaly tails add another 7-10 inches to their totally body length.  

If you’re concerned you have a rat problem but have not seen any actual rodents, look for paths or “runways” along walls and on stationary items.  Roof rats leave behind grease marks and dirt from their fur.   You may also see tracks from their feet and tails in dust.

Are roof rats dangerous?

Yes, roof rats are dangerous.  Like other types of rodents, they constantly gnaw on objects and damage things like pipes, flooring, electrical wires, and drywall. Roof rats also destroy furniture, clothing and other personal items.  A concern for health and safety, roof rats contaminate food, food preparation surfaces and food storage areas with their saliva, urine and feces.  

Why do I have a roof rat problem?

Roof rats are great climbers and poor swimmers, this means that they tend to enter into buildings by climbing trees and getting inside through attic spaces or gaps found around the roof line.

Roof rats tend to invade homes and other buildings while foraging for food, water, and/or safe shelter. Inside of homes they can be found living above false ceilings, in high cabinets, in attics, and behind walls.

‟Extremely professional and always on time. I was having an issue with mice and decided to call Arrow. They were able to get here next day and have an inspection. I set up with one of their monthly contracts and they were out to my home once a week continuously monitoring the situation until it was fully taken care of. I truly couldn’t recommend them more.”
