What Is A Roof Rat: South Shore IPM
A roof rat (Rattus rattus) is a medium-sized rodent known for its ability to climb and live in elevated areas like attics, ceilings, and rooftops. Unlike other rodents, roof rats are excellent climbers and are often found in homes, businesses, and farms, causing significant damage and health risks. They are also known as black rats or ship rats and can be particularly troublesome because they thrive in urban areas such as Dorchester. If you’re dealing with a roof rat infestation, contacting a trusted exterminator Dorchester can help you resolve the issue quickly and effectively.

- Size and Weight

- Weigh between 5 and 9 ounces, making them smaller and more agile than other rodents like the Norway rat.
- Color and Appearance
- Roof rats are usually black or dark brown with a lighter underbelly.
- Their tails are long (up to 8 inches) and help them balance while climbing.
- Climbing Ability
- Known for their excellent climbing skills, roof rats are often found in high areas such as attics and roofs.

- Habitat Preference

5 Common Signs of a Roof Rat Infestation
Identifying a roof rat infestation early can help prevent serious damage. Look for these signs:
- Droppings
- Small, spindle-shaped droppings, typically ½ inch long, are found near food sources, in attics, or along baseboards.
- Gnaw Marks
- Roof rats chew on various materials such as wood, wires, and food packaging. New gnaw marks are lighter, while older marks are darker.
- Scratching Noises
- Roof rats are nocturnal and make scratching or scurrying sounds in walls, ceilings, or attics, especially at night.
- Grease Marks
- As roof rats travel, their fur leaves dark, greasy stains along walls and rafters.
- Nests and Shredded Materials
- Roof rats build nests from shredded paper, fabric, leaves, and insulation, typically in high areas such as attics and sheds.

- Fruits
- Roof rats love fruits, such as oranges, avocados, and bananas. They often raid fruit trees or gardens.
- Seeds and Nuts
- They are attracted to nuts, seeds, and grains, especially in agricultural settings or homes with bird feeders.
- Pet Food
- Roof rats often feed on pet food left out overnight.

Roof rats are not only a nuisance but also pose significant risks to property and health, making effective rat control essential to protect your home or business.
