They’re social

Mice are surprisingly social creatures. They’ll live in burrows together with other field mice, communicating everything from reproduction, aggression, friendship, and even sadness. Researchers have found that a female and male mouse go best together, while a male mouse doesn’t do well alone with another male. Two females, on the other hand, seem to get along just fine.

A field mouse isn’t the only type there is. There’s actually many different types of mice out there you’ll probably see. More details on different kinds of mice can be found here.

What to Do When You’ve Got an Infestation

There are three reasons you’ll want to do something about a field mouse infestation:

  1. Protect your possessions: Mice will gnaw and chew on many household items like electrical wiring, couches, rugs, and clothing. This isn’t because they’re eating it; it’s actually because they’re using the pieces they chew off to build a nest.
  2. Disease: Mice carry disease. Hantavirus, Lyme disease, and Salmonella are all illnesses that are carried by rodents like field mice.
  3. Food: Field mice will be able to tell where your kitchen is and will head to it to forage for food while you sleep. If they get into your pantry, you’ll have to throw away any food they’ve touched which can be expensive – and make sure you throw it out, as mice can contaminate your food with the above-mentioned diseases.

You can get rid of field mice by plugging up any holes they’re getting into your house through, or by extermination methods like traps. There’s also poisons you can buy that are effective and kill any mice that might invade your home.

Mouse droppings everywhere

A sure-fire way to tell if you’ve got a field mouse problem is by their droppings. These mice have droppings with pointed ends that are black or brown and about ¼ inch long. It is mostly by a field mouse’s droppings that a disease will be spread, whether it’s in food or on a prep surface. If you don’t clean up mouse droppings on your surfaces properly, disease can stay on that surface and be transmitted to you.

Field mice droppingsHere’s how to make sure any surface contaminated by a mouse stays sanitary:

  • Use a paper towel to pick up any droppings you see and put them into a small trash bag, then bring that bag out to the outside garbage can.
  • Use a strong anti-bacterial and anti-viral cleaning solution to scrub the surface for at least one minute. Rinse with water.
  • Place any used towels directly into the washing machine, and throw away any paper towels into the garbage right away.
  • Thoroughly wash your hands with anti-bacterial soap.

Along with droppings, field mouse urine can also carry disease. If you touch any, do not touch your eyes, mouth, or nose until you wash your hands thoroughly with soap and warm water.

If you notice a field mice problem on your property, make sure you take action before their population quickly grows out of control. Not only it is better for your health, it can save your possessions, and give you some peace of mind that there aren’t little rodents running your household while you sleep.
