When mice get into Merrimac homes, they present a serious problem. One little mouse can chew on the wrong wire and cause a fire to erupt. Experts assert that 20 to 25 percent of structural fires in the United States are likely to be rodent-related. But, even if this were not the case, there are many other reasons to not want mice in your home. Today, we're going to share several ways to keep mice out, starting from the most difficult and moving our way toward the easiest.

Mice can chew their way into your home, but you may be surprised to know that they are far more likely to use a hole that already exists. These tiny rodents are attracted to holes and will explore them. A hole isn't just a potential entry point, it is an attractant. It will invite mice into your home.

We're not going to kid you, it is a lot of work to seal all of the tiny holes mice might use to get into your home. You're going to have to get down low to crawl underneath structures, and you're going to have to get up high, using a ladder. The tools for this job are a high-quality silicone caulk, expanding foam, metal flashing, and hardware cloth. You'll also need a screwdriver.

  • Inspect the seal around all your exterior doors. If you have gaps, you need to address them by replacing weatherstripping, door sweeps, damaged wood frames, and screens. Double doors may need to be adjusted to create a good seal all the way around.

  • Inspect your utilities. Mice often get in through gaps around pipes and wire conduits. Fill in and seal any gaps you find. It's also a good idea to seal around pipes that enter your kitchen or bathroom underneath sinks.

  • Inspect the wood of your home. If you find any spot that has a hole, replace the damaged wood or fill it in.

  • Make sure all your vents have covers and protect vulnerable points, such as louvers. Applying hardware cloth behind louvers can make a big difference.

  • Inspect your roofline. Mice can scale many exteriors as easily as Spiderman. They can climb up and start chewing on your soffits. Inspect soffits, fascia, and molding along your roofline. If you find holes, patch them up and consider bolstering these points with metal flashing.

Yard Work

It's not easy to stay on top of yard work, but the work you do in your yard is super important if you want to keep mice out. Here's how it works:

  • Keep your grass trimmed because mice prefer tall grass.

  • Remove weeds and grass from your landscaping. If your landscaping is cluttered with vegetation, it offers hiding places for mice.

  • Blow leaves out of your landscaping and out from underneath your deck, porch, stairs, and other structures. This will make mice feel exposed in these areas and make it difficult for them to chew a hole through rotting wood to enter your home.

  • When you collect dead branches, consider burning them immediately or remove them from your property. Branch piles are a big attractant for mice - termites too. Along with this, move woodpiles, scrap wood, and other wood sources away from your exterior and elevate the wood to get it off the ground.

Address Food Sources

One of the easiest ways to deter mice and prevent mice from getting inside can be to remove the attractant food offers. But it isn't always easy to remove food. Here are a few examples from easiest to hardest:

  • Remove bird feeders or move them well away from your exterior walls. Mice love seeds.

  • Make sure all of your trash is kept in plastic bags and stored in covered receptacles.

  • Clean your receptacles if they develop odors. Those odors are unpleasant to you, but they smell like dinner to a mouse.

  • Pick up acorns, nuts, or fruits from the ground. This is a chore, but it is well worth the effort.

  • Keep the interior of your home clean and free of food debris. If a mouse finds its way inside, the last thing you want is for that mouse to find food. This can be tough as it will require deep cleaning. Mice move about in very tight spaces, such as the gap between your oven and the wall.
