Signs of a Rodent Infestation

The last thing any home or business owner wants to deal with is a rodent infestation. Unfortunately, since rodents are often incredibly cautious, you may never even see one during an infestation unless it is severe. And, since we know you want to take care of an infestation before the rodents have a chance to grow in numbers, it is incredibly important to be able to recognize the signs of a rodent problem.

How Can You Tell If You Have a Rodent Problem?

Usually, a thorough inspection of your property will help you quickly determine whether or not you have a rodent problem. We recommend using a flashlight to carefully inspect dark areas such as inside of your cupboards, cabinets, closets, and behind appliances.


Small, dark droppings are a sure sign of an infestation. Depending on the size and quantity of droppings, you can identify the type of rodent present and the severity of the infestation.

Below is a breakdown of the differences between rat and mice droppings:

  • Mice: Droppings from mice are dark brown and are typically no larger than ¼ of an inch in length. They are also often pointed on both ends.
  • Rats: Rat droppings are also dark brown and range in size from ¾ - ½ of an inch long.

Rodent droppings are often found near walls, in attics, and around food sources.


Rodents use their urine to attract other rodents because it has a very strong musky odor. This odor often worsens over time as the infestation becomes more severe. If you notice stale odors coming from hidden areas, we recommend thoroughly inspecting your home for other signs of an infestation.


Once inside your property, it is likely that rodents will construct nests in areas where they feel safe, like attics.

These nests are often constructed with items found around the house or outside such as:

  • Fabric
  • Strings
  • Paper
  • Cardboard
  • Twigs
  • Grass
  • Insulation
  • Stuffing

Grease Marks

Rodents are known for digging through trash and squeezing through small, unclean areas, which means their fur is often coated in dirt and grease. When traveling around a property, they prefer to stay close to walls. Check along your walls, close to the floor for unexplained smudges of dirt and grease.

Chew Marks

As mentioned before, rodents will use anything they can find to construct a nest. That means that you can often find items throughout your home that have been chewed through such as clothing, furniture, wiring, and books. In addition, rodents will chew holes through walls and floorboards in order to be able to travel throughout your home.

Odd Pet Behavior

Have you noticed your pets are behaving a little more erratically than usual? Pets can sense rodents much easier than we can, so if you notice that they seem extra alert, are barking or meowing for no reason, or are pawing at certain areas in the home, don’t ignore it. They might be trying to let you know that something is going on.


Rodents tend to hide away behind walls and in attics and ceilings. But, just because you can’t see them doesn’t mean you can’t hear them. Rodents are mostly active at night, which is when you are most likely to hear them running around. If you hear quiet scampering, chewing, or squeaking sounds coming from those areas on your property, you might just have a rodent problem.
