How Do They Get In

It is very simple for a mouse to gain access to your home if you do not maintain the home’s exterior. Starting with removing all trash from the home, eliminating cardboard, and keeping your food airtight so they cannot chew their way to it. In many cases, there is a crack or opening on the exterior of the home. It could be at the foundation, the basement window or doors, and even the air vents attached to the attic space. So, inspecting the exterior of your home will allow you to identify a potential access point for mice and shore that area up to keep them out. Let’s take a look at why it is important to keep the mice away.

Why Is There A Concern

Unfortunately, there are a few concerns with mice gaining access to your home. Let’s review.

Keep an eye out for one called Hantavirus. This virus can affect your Pulmonary system and cause fatal respiratory issues.
  • Reproduction – mice can get pregnant as soon as 2 days after giving birth. They can end up reproducing up to 2,000 mice per year.
  • Damage – it is estimated that over 20% of all house fires come from mice or rodent damage. They can chew on electrical wires and those wires become exposed. This can cause an electrical spark or shock that can start a fire. In addition, they chew through walls, cardboard, furniture, books, and any other paper goods. Also, they will nest in your appliances, wall cavities, attic space, and anywhere they can seek shelter.

Remember that the best way to prevent mice from accessing your home is by repairing any damage to your home and eliminating easy access points. Also, limit the supply of food and water as additional preventative measures.
