Facts

  • Nests: These pests get their name from their tendency to nest in high places, but you may not just find these 8-inch long creatures in your attic; they are also known to thrive in basement environments.
  • Diseases: There are serious health threats associated with having rats in your home, including dust-carrying Hantavirus, a deadly disease that is transmitted through their urine and droppings.
  • Dangers: Rats also pose serious threats to your pets including fleas and mites that they carry and bites if your pet finds them before you do.

Food

What Do Roof Rats Eat?
Roof rats eat almost anything, but they prefer:

  • Fruit
  • Vegetables
  • Cereal products

They get their water often from their food. They eat a lot at one time, and will return to that place time after time. If they do not like a food or bait they quickly become shy of it.

Biology

Life Cycle
Roof rats mature in 2-5 months, and are adults for 9-12 months. Pregnancy takes 3 weeks. Newborns get hair after 1 week, open eyes after about 2 weeks, are weaned at 3-4 weeks. Female has 4-6 litters per year, with 6-8 young per litter.

Traits
They have keen hearing, smell, taste and touch (long whiskers), but bad vision, and are color blind. They are good at running, climbing, jumping, even swimming. They are nocturnal and explore a lot, but are cautious and shy away from new objects.

Detection

  • Chewing: Check for gnaw marks.
  • Feces: Watch out for droppings.
  • Footprints: Look out for four-toed front footprints and longer 5-toed hindprints.
  • Marks: Be aware of dark, greasy markings that are the result of fur rubbing against surfaces.
  • Plants: Check under plants for shallow burrows.
  • Outside:Look outdoors for greasy runways along walls and bare soil runways.
  • Food: Check for tiny nibbles in food.
