What Do Black Rats Look Like?
As you may have guessed, black rats usually have black fur, though some have grey or brown. Like other rats, they have bald tails and rounded ears. Black rats are considered medium-sized, growing up to 8.5 inches in length. Compared to other common house rats, this species has more prominent ears and longer tails. Their teeth continuously grow (a common trait in rodents), and they can chew through aluminum, plastic and wood. When black rats settle in houses, they may gnaw through wiring, creating electrical issues and posing fire hazards. They may also tear up cardboard, paper and even insulation to build nests.Where Do They Live?
While popular culture often depicts rats as sewer dwellers, black rats aren't great swimmers and therefore don't nest too close to water. Instead, they rely on their superb climbing skills to create nests in trees and, unfortunately, rooftops. Ironically, black rats infiltrated trading vessels as far back as the Roman Empire. As a result, you can find this species all over the world, though populations are largest along coastlines. When these rodents live in human habitats, they tend to settle in roofs, lofts or attics, visiting lower levels to forage for food. In some cases, they may build nests in kitchens or pantries for easier access to food and water. Black rats often live in groups, which increases their chances of survival in the wild but spells trouble for homeowners.What Do They Eat?
Rats have incredibly versatile diets, allowing them to live off human leavings. Studies indicate that black rats can subsist on the following:- Bird eggs
- Insects
- Fungi
- Fruit
- Seeds
- Leaves and stems
What Should You Do If You Have an Infestation?
Since rats are nocturnal, you probably won't see one in the flesh. Instead, you'll run into signs of their presence:- Tiny footprints
- Chewed furniture
- Droppings
- Grease smudges on walls or floors from contact with fur
