As a professional exterminator company, we take mouse and rodent activity seriously. Deer mice have been found in rural King and Snohomish counties and are common east of the Cascades. The deer mouse is an especially harmful mouse species that typically take up shelter in the cold, winter months. Suspected mouse infestations should be treated with caution.

Signs Of Deer Mice

Deer mice infestations are serious rodent issues as they are carriers of hantavirus. If you see any of the following signs of a deer mouse infestation, please call a pest control service specializing in rodent extermination immediately.

  • Mouse Droppings – Similar in size and shape to rice, they are about a quarter-inch or less in length. These rodent droppings are dark in color, smooth with pointed ends. Deer mice feces are found on floors, cabinets, and baseboards.
  • Food Caches – Deer mice are more likely to cache their food and store it near their nests. Typically their piles of food include nuts, berries, seeds, and fruits.
  • Urine Smell – Deer mice will also leave behind urine, creating a musky smell in houses.
  • Damage – Homes may see damage to upholstered furniture, mattresses, clothing, paper, or other materials as these rodents and mice build their nests in homes.
  • Nests – Another sure sign of mice are nests – although rarely seen in houses. They typically build their mouse nests in drawers, wall voids, floor voids, false ceilings, and undisturbed areas of debris. Deer mice and rodents stay close to their food sources.

Deer Mice & Diseases

One of the significant concerns of deer mice is the diseases they carry. The mouse may look cute and harmless, but contact with their feces, urine, or saliva and create serious health issues in humans.

The most serious of these diseases is hantavirus. Hantavirus is contracted through mouse carcasses or inhaling air-borne urine droplets, droppings, or saliva of infected deer mice. Often this happens when cleaning vacated buildings, spring cleaning, or sweeping nests in basements, attics, and other areas of your house. Touching items or eating foods contaminated by the mouse can also lead to exposure to Hantavirus.

Suspected deer mice infestations should be treated with caution as 50% of all Hantavirus cases result in death.
