The Cozy Lives Of House Mice

Summary: House mice enjoy being warm and cozy inside a house, but they sure cause a lot of problems! This blog details the lives and habits of house mice, including their appearance, habitat, abilities, pest status, and warning signs. Green Pest Services provides reliable mice control all year long.

This winter weather has us wanting to stay in our cozy homes for the foreseeable future. Another mammal that loves hiding from the harsh cold is the house mouse. This pest is named after its favorite habitat: our homes.

Once it finds a hidden corner in which to create a nest and start building its family, the house mouse is happy to stay in a house for the rest of its life (literally). But how do these rodents get inside, steal our food, and build their families without being caught first? Let’s find out by exploring the cozy lives and habits of house mice!

Identifying The Pest

House mice look like any other mice, which makes sense considering they’re the most common mouse species in the United States. They don’t mind living in close proximity to humans as long as the mice have a secluded nest to use as a retreat.

The typical features of a house mouse are:

• Gray coloring with a white belly
• A length of up to 2 inches
• A long, hairless tail
• A rounded body
• A pointed snout
• Large ears

House mice are most common in winter because they’re desperate for a shelter from the fatal cold outside. They are found in a variety of environments, including urban, suburban, and rural. As long as they have a cozy shelter, house mice aren’t picky with their surroundings.

What’s In A Name?

The name “house mouse” sounds like a nice little creature that we wouldn’t mind having in our homes. In reality, house mice are disease-ridden pests that cause expensive damage and multiply at an alarming rate. They stay in dark and quiet areas that are in close proximity to food for some late-night foraging.

House mice can live outside, but they would much rather stay in our cozy houses. They’re even more desperate when the outdoors doesn’t have the food and resources they need. These mice build nests out of random materials they shred and messily pack together to create a nice space for their offspring. Their favorite materials are paper, fabric, cotton, and insulation.

Who’s Afraid Of Little Old House Mice?

For such small fuzzy creatures, house mice have quite a few abilities that make them a formidable foe for any pest professional. These mice are curious about their surroundings and can cause their own demise by sniffing their way into a trap or bait box, which is great for us but unfortunate for them.

House mice can:

• Climb
• Jump up to 1 foot high
• Hear very well
• See up to 6 inches away
• Adapt to their environment
• Produce up to 10 litters a year, with about 6 offspring in each litter
• Slip through cracks and gaps that are a quarter of an inch wide (the width of a pencil)

Much of the damage caused by house mice is due to their strong teeth and habit of chewing on everything. Wood and insulation are already worrisome chew toys, but the real concern starts when they turn to electrical wiring. Chewed and frayed wires are fire hazards, which explains how rodents cause 20% of undetermined house fires every year. Long story short, you don’t want house mice in your house!

The Pest Status

The short answer to this subtitle is that the house mouse’s pest status is very high. The longer answer involves going into their destructive habits, so let’s go!

House mice only eat a little at a time since they don’t need much to be satisfied, given their small size. However, they contaminate everything they touch. This means that any food they eat is immediately contaminated, so it’s important to throw out anything touched by house mice. Their favorite foods are seeds, grains, cereal, fruit, nuts, insects, pet food, and peanut butter.

Although they’re usually nocturnal, house mice can still be active during the day. They spend their time damaging the house’s materials with their teeth, contaminating our food, and spreading bacteria everywhere they go. The mice transmit diseases through their droppings, urine, bites, saliva, and feet. Three diseases that house mice often transmit are hantavirus, rat bite fever, and salmonellosis.

They can also bring smaller pests into the house, which then can impact the people and pets living there. House mice can have fleas, ticks, and mites. If infested mice are left alone, these pests and their allergens can spread to the rest of the home. House mice are already a health hazard, so bloodsucking pests create a new realm of stress-inducing possibilities.

Signs Of An Infestation

With all of this in mind, you may be wondering how to tell when house mice are living in your home. After all, the best way to solve a pest problem is to get it treated ASAP. The more mice that live in the house, the more time it will take to eliminate them. It’s not impossible to end an long-lasting mice infestation, but it’s best to target them in the early stages.

The most common signs of a house mice invasion are:

• Scratching sounds (especially at night)

• Gnaw marks

• Droppings

• A jagged (mouse-sized) hole in the wall

• Shredded materials

• Oily rub marks on walls and furniture

• A musty or urine-heavy odor in a certain area

• Shredded materials scattered in the house

• A burrow in the house or yard

• Your dog or cat being agitated near a specific spot (wall, crawl space, closet, etc.)

• Any live or dead house mice
