welcome to the rat and why rodent trapping is important.


What am I?

We are the Norway rat (Rattus norvegicus) we are strong, very aggressive, and able to adapt to cold climates.

  • We  are 12-18 inches long, and weigh up to 16 ounces.
  • Our muzzles are blunt, and our bodies look thick and heavy.
  • We have small eyes, naked ears, and coarse fur.
  • Our tails are 6-9 inches long, scaly and nearly naked.
  • We have brown to dark gray fur, with scattered black hairs, and we are gray, grayish brown or dirty white underneath.
  • Breeding occurs mostly in the spring and fall.
  • Our females will begin breeding at 40-45 days of age.
  • Our Females often mate within 18 hours of giving birth.
  • Our gestation is as short as 21 days, and a litter is 2-14 pups (the average is 7).
  • Our females produce 8 or more litters per year.
  • We continue to breed until 18 to 24 months of age.
  • Our newborn have no fur and are blind. But they grow rapidly.
  • In 2-3 weeks their eyes and ears are open.
  • Our pups are weaned in 3 weeks, and are sexually mature in 3 months. However, our male pups must develop sufficiently to challenge an adult male for supremacy.


Where do we like to live?

We can be found in and around every town and farm in the country. It is estimated that there is one us for every person living in the United States. We have followed man to almost all parts of the world. We have no respect for social class; We are equal opportunity pests. We are so closely linked to man we are called domestic rodents. Man supplies their three basic needs: food, shelter, and water.  We can be found in your homes, supermarkets, restaurants, livestock pens, and farm fields. Warehouses, grain mills, elevators, silos and corncribs are especially vulnerable to our infestation. We will eat anything man or his livestock eats. We are active at night. We are seldom seen during the day except when populations are exceedingly large. We can crawl through very small crevices, which makes it hard to confine our movement. Even if you can't see us, you may hear us moving after dark. If your pet paws at a wall or cabinet it may be after one of us. Cats and dogs are not much of a deterrent to us, just FYI. 


Can we live in your attic? Please!

  • Most of us carry Tularemia which is a disease of animals and humans caused by the bacterium Francisella tularensis. Us and Rabbits are especially susceptible and often die in large numbers during outbreaks.  The bacterium that causes tularemia is highly infectious and can enter the human body through the skin, eyes, mouth, or lungs. Symptoms of infection vary depending on the route of entry.  Humans can acquire tularemia by inhaling dust or aerosols contaminated with Francisella tularensis bacteria. We also like to defecate and urinate any and everywhere. I guess I now know why I can't stay with you. 
  • If we are a problem call Topper's Wildlife Removal they'll help you get rid of us. They offer rodent trapping in Dallas Tx. and rodent trapping in Garland Tx.
