Facts

  • Common Pest: One of the more common pests found in the United States, the house mouse frequently takes up residence in homes and other manmade structures.
  • Problems: When the rodents invade homes, they consume and contaminate foodstuffs and wreak havoc on structures and property.
  • Disease: House mice also spread diseases such as salmonellosis and are known carriers of other vectors, such as fleas and lice.

Food

What Do House Mice Eat?
House mice are omnivores with a diet focused on:

  • Seeds
  • Roots
  • Leaves
  • Stems

The pests also feed on insects and other sources of meat when available. When house mice live with or near humans, they become opportune feeders that will eat any available foodstuff or household item, including glue, soap, and paper.

Biology

Birth
Female house mice can produce between 5 and 10 litters per year, with each litter containing anywhere from 5 to 12 young. Pregnancy lasts up to 21 days until the young are born furless, blind, and helpless.

Adults
Newborn house mice develop quickly, maturing to adulthood in just 6 to 10 weeks. Females are ready to mate about a month after birth, while most males reach sexual maturity two months after being born.

Lifespan
The average lifespan of a house mouse falls around one year in the wild and up to three years in captivity.

Detection

  • Droppings: Fecal pellets, urine stains, and grease trails may indicate a house mouse infestation.
  • Damage: Look for gnawing damage and tracks along baseboards.
  • Sounds: Listen for audible signs, such as squeaking and scratching in walls, ceilings, attics, and crawlspaces.

Problems Caused by House Mice

Spread of Disease
House mice contribute to a variety of issues in and around the home. The rodents can spread diseases that cause varying levels of sickness in humans, as well as contaminate food with their droppings.

Damage
Additionally, the pests are voracious feeders that consume large quantities of stored food and crops. House mice can also damage woodwork and building structures, as well as furniture, wiring, and even clothing, if left unchecked.

Signs of Infestation

  • Sight: The most prevalent sign of a house mouse infestation is either seeing the rodents themselves or finding their droppings around the home.
  • Sound: Sounds of scratching, rustling, and squeaking coming from walls, attics, crawlspaces, sheds, or garages may also indicate a large incursion of mice.

Prevention Tips

  • Sanitation: Proper sanitation may help reduce the likelihood of a house mouse invasion. While no amount of sanitation will keep mice away for long if food still remains available.
  • Attraction: Preventative actions like properly storing groceries and pantry items, eliminating attractive nesting sites, and sealing off points of entry to the home can help.
  • Entry: Applying steel wool mixed with caulk around openings for pipes and wires may also help to keep mice away, as does the use of metal and concrete where necessary.

Tips for Removal from Home

House Mouse Traps
Store-bought traps and baits can eliminate small populations of house mice. For larger infestations, a trained pest control specialist may need to come remove the problem.
