Do you have Roof rats in your attic? We know how to get rid of roof rats. First, let’s describe this high climbing and persistent attic dweller. Roof Rats, which are also called ship rats or black rats, have a scientific name of Rattus rattus and they can be black, brown or gray. They have a tail that is longer than their body that is charcoal grey in color, uniform in width and it is prehensile. Roof rats are great at climbing and will gladly move into your attic. Roof rats like buildings, especially living in attics, running along rafters, pipes and electrical wires. Roof rats are neophobic, which means that they are afraid of new things… such as roof rat traps or roof rat poison bait stations. Early sailing ships from East Asia originally brought roof rats to North America, and roof rats have infested every corner of the world.

Roof Rat Reproduction
After 20-24 days of conception, hairless and eyes closed, 5-8 young per litter emerge in the nest. Within one week fur has formed, at 9-14 days their eyes open, they nurse until 4-5 weeks old and are totally on their own at 3 months of age – and ready to breed. Roof rats have the fastest breeding cycle of all rat types. Two roof rats in the attic can quickly become ten.
Roof Rat Feeding Habits
Roof Rats are omnivorous and will consume almost anything and will travel 100 to 300 feet to find it. Chewing on electrical wires is a common practice of these attic dwelling rodents.
