Similar in size and appearance to the deer mouse, white-footed mice have tawny brown back fur, white belly fur, and of course, white feet. This type of mouse also has a large ears and eyes and a long tail. 

How do mice get inside?

Mice can enter homes and businesses through small spaces found in exterior walls. They only need a space that is about ¼ of an inch in diameter (about the width of a pencil) to enter through.  House mice often squeeze through cracks and crevices in the foundation, spaces found around exterior windows and doors, spaces around utilities entering your home, and through vents or spaces found around heating and air conditioning units.

Why do mice infest homes and businesses?

Mice will infest homes and businesses any time of the year while searching for food and water.  Mice can become a particular nuisance in the fall and winter when they actively search for warm, safe shelter to stay in over the winter months. 

Are mice dangerous?

Yes, mice are dangerous; they can spread serious diseases including: salmonellosis, leptospirosis, dysentery, and lymphocytic choriomeningitis.  Deer mice and white-footed mice are two types of rodents in Maine that can get hantavirus, a serious disease caused by a virus that can affect your lungs. Additionally, white-footed mice are primary carriers of the Lyme bacterium Borrelia burgdorferi and are a popular host of black-legged ticks.  All three types of mice are known for introducing other ticks and fleas that carry their own set of diseases that can be spread to people.  

Mice are not only a danger to people but also property. Because they need to constantly chew, mice are capable of inflicting significant structural damage to properties and belongings. What's more, mice also have the potential to start fires in homes and businesses

Damages caused by mouse

House mice can cause significant damages to properties, personal items, and inventory.  House mice chew constantly and will chew through and damage wires (which can set off fires as noted above), pipes, insulation, drywall, and flooring; along with pictures, books, boxes, clothing, and furniture.  Mouse droppings and urine will contaminate insulation, other building materials and possessions.

How do you get rid of mice?

Mice are difficult to find and eliminate because they often nest in hard to reach areas of your home or business. Therefore, the best way to ensure that all mice are found and removed is with professional help.  DIY mouse control is more often than not ineffective and does nothing to get to the root of the infestation - how mice are entering your property in the first place.

Mouse prevention tips

Don’t want a mouse problem in or around your home? We don’t blame you, they’re nasty creatures.  To help prevent a mouse problem, our Maine pest control pros have recommended the following tips:

  • Seal cracks in the foundation.
  • Place a tight fitting cap on all chimneys.  You should also inspect the chimney and fix any loose or missing roof shingles.
  • Caulk gaps found around exterior windows and doors.
  • Trim back trees and shrubs from the exterior of your home. Mice will use their branches to gain easy access to your home.
  • Keep tight fitting lids on outdoor trash cans and place them a distance away from the exterior of your home.
  • Store food in sealed containers and do not leave open containers or food out on the counters for easy access.
  • Make sure that spills and crumbs are cleaned up quickly and wash dirty dishes regularly.
  • Reduce areas of clutter and routinely remove garbage from your home.
