House Mouse

Mus musculus

high CASE #MWP-0003

Left 70 droppings in your kitchen drawer overnight. No remorse.

How We Take Them Down

  1. Snap trap placement along walls and in travel corridors
  2. Bait station deployment in protected, out-of-reach locations
  3. Exclusion: sealing all entry points with steel wool, hardware cloth, and caulk
  4. Interior crack and crevice treatment in wall voids
  5. Ongoing monitoring with glue boards in low-traffic areas

Prevention Tips

  • Seal any hole larger than a dime — mice can compress their skulls to fit through a 1/4-inch gap
  • Store food in hard-sided sealed containers, including pet food
  • Keep clutter in garages and storage areas to a minimum to eliminate nesting sites
  • Inspect the roofline, foundation gaps, and utility penetrations every fall
  • Keep grass trimmed short and move woodpiles and debris away from the home's exterior

Fun Facts

A single mouse can produce 35,000 droppings per year. You're welcome for that mental image.

Mice don't need to drink water regularly — they can get sufficient moisture from their food. Removing water sources alone won't solve your problem.

A female house mouse can have up to 10 litters per year with 5–6 pups each. The math is not in your favor.

Mice are neophilic — they're actually attracted to new objects in their territory. That new trap you set? They'll investigate it. Use this against them.

Field Notes

The house mouse is proof that something small and technically kind of cute can be an absolute disaster for your home. These opportunistic tenants move in through gaps no larger than a dime, and once inside, they operate under an unspoken policy of “what’s yours is mine” — your food, your insulation, your electrical wiring, and your peace of mind. A mouse infestation isn’t just a nuisance; those gnawed wires are responsible for a meaningful percentage of house fires with no apparent cause. They’re also prolific breeders, so “one mouse” is essentially never actually one mouse. If you’re hearing scratching in the walls as you drift off to sleep, congratulations — you have roommates.
