Mice or Rats: What Type of Rodent Is Living In Your Home?

If you have found some of these signs throughout your house, you likely have a rodent infestation of some sort. But whether your pests are rats or mice impacts how you should handle your pest problem. Look for these indicators to figure out what type of rodent is living in your home.

The Size of Droppings

Check floors for droppings near spaces with food or possible nesting areas. They can typically be found behind cupboards or furniture. When you find the rodent excrement, evaluate its size. Rat droppings are much larger than a mouse’s. A rat’s droppings are typically around 1/2 inch or larger whereas a mouse’s droppings are less than 1/4 of an inch. Both droppings are brown, cylinder-like and pointed/tapered at the end. Droppings are a tell-tale sign that can help you identify what kind of a rodent infestation you have.

Gnaw Marks

Rats and mice have very different gnaw marks because of their size of teeth. Rats have much larger teeth, making their marks on a home much more visible. Typically, they will eat or bite wood, wires and plastic material. Their bite marks are about 1/8 inch long but could cause great damage if rodents are left unchecked for a while. A mouse will similarly aim for these areas of a house, but will only leave scratches due to their smaller bite.

Watch and see if you can spot rodents in your home. If you manage to see one, you can figure out whether it is a mouse or a rat by its appearance.

Mice are small creatures with large, round ears and small eyes. They have thin fur and a hairless tail. When mice are matured, they will measure anywhere between 6-7 inches long.

In contrast, rats are much larger than mice and usually have coarse red, grey or brown fur. Their tail is also hairless, but much longer than a mouse’s. Mature rats will measure about 11-19 inches long.
