What You’re Actually Dealing With

Norway rats and roof rats are common pests in many areas. Norway rats are larger, with brown fur and a thick body. They prefer to burrow in the ground and are often found in basements or near sewer systems. Roof rats, on the other hand, are smaller, with a more slender body and black fur. They are excellent climbers and prefer to nest in trees or attics.

Signs You Have Norway Rats or Roof Rats

Identifying which type of rat you have is crucial for effective control. Here are some signs to look for:

  • Size: Norway rats are about 7-10 inches long, while roof rats are 6-8 inches long.
  • Color: Norway rats have brown fur with lighter underbellies. Roof rats are typically black or dark brown.
  • Droppings: Norway rat droppings are larger and blunt-ended, around ¾ inch long. Roof rat droppings are smaller and pointed, about ½ inch long.
  • Nesting Sites: Look for Norway rats in lower areas like basements. Roof rats are often found in higher places like attics or trees.
  • Tracks: Norway rats leave tracks in mud or dust that are wider apart. Roof rat tracks are closer together.

How to Get Rid of Norway Rats and Roof Rats

Once you identify the type of rat, you can take steps to get rid of them. Here’s a step-by-step guide:

  1. Step one: Inspect your home for entry points. Seal any gaps or holes larger than a quarter.
  2. Step two: Remove food sources. Store food in airtight containers and clean up crumbs and spills.
  3. Step three: Set traps. Use snap traps for Norway rats and smaller traps for roof rats. Place them along walls where you see signs of activity.
  4. Step four: If needed, consider bait stations. Use them with caution, especially if you have pets or children.
  5. Step five: Monitor the situation. Check traps regularly and dispose of any caught rats promptly.

  • Keep your yard clean and free of debris.
