4 Ways to Avoid Invasive Mice Coming Into Your Home

It can be difficult to figure out what kind of critter you’re having a problem with unless you can physically catch sight of them you might believe that a sign for one pest is actually indicative of another.

It’s happened again. You’re sitting in your living room enjoying a movie with your family. Or perhaps you’re at the dinner table chowing down on your favorite meal. Above you, there’s a scratching noise.

You stop whatever you’re doing and listen closely, and the noise becomes almost deafening now that you’re focused on it. That’s right … you have mice in your ceiling. Not only do these rodents often contaminate your food and sometimes make a lot of noise, but they also carry a variety of diseases and can chew through wiring to create a fire hazard.

When you need a mice exterminator, call your local pest control company for help.

Tell-tale Signs of Mice Infestation

Is it a mole or a mice infestation? Moles and mice sometimes cause this type of confusion. Although there is a size differential, the fact that they are both small critters that stay out of sight to avoid detection confuse some homeowners. So what do you look for?

To clue you in on what type of pest is invading your home, let’s take a look at 3 mice infestation signs:

Sign #1: You find unexplained holes in your food containers

As you may already know, mice love to chew. Their sizable incisors can enable them to chew through a huge variety of materials. Very often, the first mice infestation signs occur when you notice holes in your food containers.

Once they get into your cupboards or pantry (often by chewing through the wood), mice will eat their way through cardboard boxes and bags of food in order to eat. The worst part about this is that this will contaminate your food.

Of course, chewing through food containers isn’t the only fear. Mice have been known to gnaw through electrical wiring as well, which can cause a fire hazard in your home.

Sign #2: You hear scratching noises in your walls

Mice are not the quietest of creatures. Very often, they take up residence — or at least partial residence — in your home’s walls. They sleep there, defecate there, and basically treat your walls as a safe haven, foraging for food during the day and returning to the walls at night.

If you listen closely, it isn’t difficult to hear scratching sounds in various areas of your house as the mice move from one location to the next. Mice are nocturnal animals, so if you’re trying to listen to them, it’s best to do so at night.

Sign #3: You discover small droppings in various places

These annoying pests have no self-control when it comes to urination and defecation. When they have to go, they go. Doesn’t matter where they are or what they’re doing. This is a big reason why these little rodents often contaminate food.

But the danger is not simply about being grossed out. Mice droppings can spread diseases, such as the Hantavirus. If you find a large collection of droppings, don’t simply sweep them up. Instead, make sure that you have proper ventilation, and wear a mask that will protect you from inadvertently breathing in harmful materials.

Sign #4: You find tracks

Rodents skitter from one place to the next and they don’t make a habit of covering their tracks. Another sign to be on the lookout are tracks left in dusty areas within your home. If you do find any rodent tracks, you should be able to identify exactly what kind of rodent has made its way into your house based on the size of its tracks.

Solutions to Rodent Problem in Your House

To avoid mice infestations, we suggest these three simple strategies:

#1: Seal your home’s crack and gaps

Mice infestations are possible because the little rodents can get inside your home. Unless you’re leaving your doors open all the time, most mice will enter your house through gaps and cracks leading inside.

To stop them from coming in, it is important you seal your house from rodents. You typically don’t have to worry about the smallest of gaps, since mice won’t be able to fit through them.

For medium-size and larger holes, however, you’ll want to seal them with either expandable spray foam or weather stripping.

Why Mice and Rats Infestation Makes Sealing Holes Difficult

A number of pests can be stopped by sealing up or at least blocking, the holes that are being used to get inside your home. In this respect, mice present a very annoying problem, because they can sometimes chew through normal remedies that you might employ. If you simply set a block of wood against a large gap, for example, the mice might just eat right through it.

  • Common Places for Entrance

The first thing you should do when sealing holes inside and outside your home is to target the most common problem areas. Start with the foundation of your house, which is a common place for mice to use to get inside.

Then, turn your attention to water pipe openings and vents, and block those with metal or concrete. Once that’s all finished, make sure your windows and screens are secure.

  • Concentrate on the holes best suited for mice

Luckily, you have one advantage when it comes to sealing holes against mice infestations. Mice are much larger than insects. With insects, you have to seal even the smallest of cracks and gaps inside and outside your home.

With mice, you don’t have to worry about these. Instead, concentrate on the holes that are larger than 1/4 inch. This should provide you with enough protection to stop a possible infestation from occurring.

  • Seal Holes with Steel Wool

Sealing holes often come in the form of household caulking, expandable spray foam, and weather stripping. Most people probably don’t think about using steel wool to fill in cracks and gaps around their home. The possibility of mice infestation, however, can make this tactic necessary.

Steel wool is effective in preventing mice infestation because the rodents won’t typically chew through it. To hold the steel wool in place, apply household caulking. When you do, make sure that you smooth out the caulk as much as possible.

If it isn’t smooth, mice will be able to get a grip on it and pull it loose. For further protection, you may want to cover the edges with metal. This will definitely prevent the mice from being able to chew through the seal.

#2: Take out your trash

Like other pests, mice are attracted to your garbage. They are looking for sustenance, and when they catch wind of the discarded food in your trash, they will do whatever they can to find their way into your home so they can partake in your discarded treasures.

If you want to prevent this, the best way to stop mice from being attracted to your trash is to get rid of it. This means that you must take out your trash on a regular basis.

For garbage with a strong odor, you might even want to consider placing these items in a plastic bag of some kind to guard against mice smelling the trash you’ve thrown away.

This can sometimes be difficult, so it is advisable that you at least be sure to take out your trash as soon as it’s full so that it’s no longer in your house.

#3: Remove all food and water sources

Put all food in containers that can be completely sealed and that are made of a material that can’t be chewed through, such as metal or hard plastic. Put items such as bags of chips, flour, or sugar in chew-proof containers because rodents will be able to gnaw through most packaging.

Also, don’t let water pool around your home and fix all indoor plumbing problems. With these steps, you’ll be taking away the rodents’ principal reason for entering your home—to get food and water.

#4: Set up some tried-and-true mousetraps

When it comes to rodent extermination, mousetraps are hard to beat. Although some homeowners will resort to poisons to maintain control, mousetraps can keep mice under control without the need for dangerous chemicals.

The only real problem with mousetraps is that most of them require that you switch out bait on a regular basis. Of course, this is a small price to pay for your peace of mind.

If exterminating isn’t your thing, you can always choose a more humane technique. This can be done in the form of traps that are designed to catch mice, rather than kill them.

If you decide to go this route to help rid your home of mice infestations, of course, you’ll need to figure out what to do with the captured mice. Beware that sometimes mice are smart enough to avoid traps.

#5: The professional pest control company

Mice infestations can quickly get out of hand. A few mice are one thing. But dozens or more can present a big problem that many homeowners don’t want to deal with.

Plus, the time involved in a big infestation can allow more chance of food contamination and disease. There’s no shame in calling professionals if the mice in your house are too much for you to handle.
