If You See One Mouse, How Many Do You Have?

If You See One Mouse, How Many Do You Have

You’ve had some strange happenings around your home lately, including noticing weird grease marks on your walls and your pets acting strangely. Your normally-calm dog starts barking and growling at your walls out of the blue, and you’re not sure what the issue could be. Then, you spot it: a mouse. But you just saw one, so it can’t be that bad of a situation, you tell yourself. But in reality you’re thinking: If you see one mouse, how many do you have?

Unfortunately, locating a single mouse on your property is not that different than finding a needle in a haystack. These small rodents keep to themselves, and they’re relatively quiet. With their main predators being adept hunters—including cats, snakes, owls, hawks and foxes—they have learned how to be excellent hiders and know how to get around without being detected.

So, if you’ve seen a mouse, especially during daylight hours, it likely means that there are (at least) several more that you aren’t seeing. Mice are nocturnal, so if you’re seeing them during the day, it usually means that their nests have become overcrowded and they’re looking for a new place to live. Which brings us to our next point: A single female mouse can produce up to eight babies in a single litter and consistently produces six babies per litter.

Moreover, gestation periods are very short for mice. In one year, that lone mama mouse can produce up to ten separate litters! That quick math adds up to sixty babies in one year from just one mouse. Before you know it, you may unknowingly be feeding more mice than you can possibly keep track of, and having multiple mice in your home can result in serious damage.

Call in Professional Help 

So, should you get professional pest control help if you see a single mouse?

In short: yes. The sight of one mouse is enough to take action. Be proactive and contact trusted rodent control professionals as soon as possible to prevent putting your property and family at risk. Why at risk? Mice and other rodents can spread disease, contaminate food, damage your belongings because of their incessant chewing and even introduce other pests into your home, including fleas and ticks.

With the realization that you likely have a mouse infestation, you probably have a lot of questions going through your head, like how many mice is considered an infestation? In this post, we’ll review everything you need to know about these creatures, including where they hide, your chances of getting sick from them and how to prevent having mice take up residence in yours. But first, let’s start with why mice may choose to live in your home.

Why (And How) Do Mice Take Up Residence In Our Homes?

Like most animal visitors, mice are just looking for a safe and secure place to live and breed when they nest in our attics, crawl spaces, garages, sheds and other areas. They need food, water and shelter, and your home can provide it to them if they are able to gain access.

Mice are highly adapted to invade our property in search of a viable place to raise a family. For example, mice can crawl through the smallest spaces in your foundation or entryways to make themselves at home. They have an uncanny ability to find cracks and openings previously unknown to homeowners. Even if you built a moat around your house, this likely wouldn’t be much of an obstacle to mice because they are great swimmers, jumpers and climbers.

If you are diligent about covering up potential entry points, you may still be susceptible to a mouse infestation because mice can chew through all kinds of materials, including:

  • Drywall
  • Soft Concrete
  • Rubber
  • Insulation
  • Aluminum
  • Power Lines

Once mice get into your home, where are you most likely to find them hiding?

Where Do Mice Hide?

Mice will hide anywhere that they believe is safe for them and their litters. Anywhere they have warmth, food nearby and can generally live undisturbed is a great spot for these rodents to stick around.

Some of the most common mouse nesting spots include:

  • Inside or beneath kitchen or bathroom cabinets
  • Inside or behind drawers
  • In your walls, particularly near heat sources
  • Behind kitchen appliances
  • Under furniture
  • In secluded areas of rarely used rooms, such as in the attic, basement or garage
  • In old cardboard boxes

Obviously, mice don’t just live indoors. A family of mice can easily feel comfortable in shrubbery, woodpiles, sheds or other areas that provide adequate shelter for their families. Mice living outdoors will happily settle for the food scraps you keep in your garbage bin and compost pile. The small size and dietary flexibility of mice make it easy for them to take up residence around and inside your property.

Previously, we mentioned that mice are great at going undetected for long periods of time. They’re great at this, because they don’t just run around in your hallways—mice can travel through your walls, as well.

How to tell if you have mice in your walls

How To Tell If You Have Mice In Your Walls

Hearing scratching noises inside your walls is one of the most obvious signs that you have a mouse infestation. Even if you don’t see droppings or physical rodents yet, those noises are a good sign that it’s time to call in a pest control professional.

If you have pets and you have noticed them staring, barking or growling at the wall, that is another sign of mice nesting in your home.

Any of these additional signs are indicators that you have unwanted guests:

  • Mouse droppings
  • Musky odor of urine and droppings
  • Gnawed marks on furniture, food packaging or walls
  • Worn-down “runways” where mice tend to move back and forth
  • Nests made out of shredded paper, string, rags or other home materials

Unfortunately, some homeowners are unaware of the dangers that come along with these creatures, including dangers that can stick around even after all of the mice are gone.

Chances of getting sick from mouse droppings

What Are My Chances Of Getting Sick From Mouse Droppings?

Mice tend to be depicted as harmless little creatures who enjoy a nibble or two of cheese while they pop in and out of a hole in the wall. Unfortunately, the real story of these creatures isn’t quite so positive. While they certainly will eat cheese, mice don’t mind eating virtually anything else that’s put in front of them. In desperate situations, mice will even eat each other.

Moreover, their squeaks can keep you up at night. They can contaminate your food and chew through just about anything, putting your family at risk of disease and electrical fires. One of the most serious risks of having a mouse infestation in your home is an illness you can get from mouse droppings: Hantavirus.

People catch Hantavirus when inhaling airborne particles in mouse urine and droppings. Thankfully, it’s relatively rare. The first case appeared in the U.S. in 1993, and as of 2017, there had only been 728 reported cases.

If you see small, brown, cylindrical droppings around your home, these are likely mouse droppings. These should be cleaned up using gloves to protect yourself and bleach to sterilize the area.

Unfortunately, Hantavirus isn’t the only way you can get sick from mice. Homeowners should throw out any food that mice have consumed in case of contamination.

Other than diseases, additional issues come with having mice in your home. Like many rodents, mice teeth don’t stop growing, so they are constantly chewing to shorten them. If the mice in your home decide to start chewing through your electrical wiring, this behavior can lead to expensive damage. In the worst case scenario, the exposed wires can spark and lead to a house fire.

Fortunately, there are ways that you can prevent mice from living in your house.

How to prevent mice

How To Prevent Mice From Living In Your Home

The first step in keeping mice from spending time on your property is learning how to get rid of rodents. This typically involves hiring a pest control professional with experience in wildlife and rodent removal. Then, take the following steps around your home to avoid future visits from these rodents:

  • Seal up or screen any openings that could be a potential entryway for mice. This includes the chimney, windows and weather stripping that may have become worn. Remember, mice are tiny and nimble, so don’t skip over any holes you see, no matter how small they are.
  • Don’t tempt mice. Seal food in airtight containers, even if it’s already in a package. That includes pet food and birdseed.
  • Take out the garbage regularly. Set up bins so that they are away from your house. Move your compost pile, woodpile and any other natural hiding spots away from your home.
  • Dehumidify the attic, basement, crawl spaces and anywhere that could be dark and damp. Fix leaks and eliminate any sources of moisture that could attract rodents.

When it comes to a mouse infestation, the most effective option is to contact a professional who understands rodent control.
