What do deer mice look like?

Adult deer mice are distinguished from the typical house mouse by their slightly larger body size. They have a head and body length of 2 3/4 to 4 inches, a tail length of 2 to 5 inches. Adults weigh between 3/8 and 1 1/4 ounce.

Deer mice are bi-colored, the top of their body is usually a pale gray to deep reddish-brown and their belly is white. The tail is covered in short hairs and is also bi-colored-dark on top and light on the bottom; they have large ears which are covered in fur and black eyes and are very common throughout our New Jersey service area.

Are deer mice dangerous?

Deer mice are dangerous to have living inside your home, around you and your family. Not only will they contaminate your family’s food sources and food prep areas with their saliva, urine and feces, they can transmit serious diseases. Deer mice are primary carriers of the very serious Hantavirus which causes Hantavirus Pulmonary Syndrome (HPS).

Why do I have a deer mouse problem?

Deer mice invade homes and properties that offer them easy access to their basic needs- food, water, and of course warm safe shelter. Deer mice are typically live outside and don’t usually invade the inside of homes; however they can be found invading homes located in communities that border a field, park, golf course, or that are located in a rural area.

Can I control deer mice?

What are signs of a deer mouse infestation?

There are many things you could notice around your home that could be attributed to damage caused by mice. Some of the most common signs are:

  • Droppings
  • Urine smells
  • Scratching or running noises
  • Gnaw marks 
  • Shredded paper or insulation - this is typically their nest 

How do I make my property less attractive to deer mice?

There are several steps that you can take to deter deer mice from choosing your New Jersey home to be their home.

  • Inspect the exterior of your home and seal any openings found. Caulk gaps found around windows and doors and seal cracks and crevices found in the foundation.
  • Trim back trees and bushes from the exterior of your home.
  • Repair loose or missing roof shingles and make sure that chimneys have tight fitting caps on them.
  • Place trash that is being stored outside until pick-up day inside of containers that have tight fitting lids, or even better locking lids.
