How to Prevent Mice From Getting Into Your House

A mouse infestation is no joke! These rodents can contaminate food, bring bacteria into your property, and chew through wires, insulation, and furniture. You definitely don’t want any of that to happen!

So, how do mice enter your home? Usually, these creatures fit through holes in your house, such as gaps in windows, ceilings, walls, sewer lines, and soffits. They can also get into your property through sinks and bathtub drains if you haven’t sealed your drainage systems properly. Sealing these gaps and holes is critical to prevent future infestations.

How to Seal Mouse Entry Points in Your Home

First, you must identify where mice enter your property, which can be difficult. Smaller mice can fit through holes in your house that you might not even notice, making it hard to find the root cause of your infestation.

Seal any visible holes and cracks in your property with steel wool or caulk, which you can find in your local hardware store. Alternatively, you can use a combination of these materials to stop mice from entering your home. Pay close attention to areas of your house that contain pipes, which can provide mice with quick access to your property.

Sometimes, it’s just easier to call in the experts! The best pest control companies in Maryland and Northern Virginia can identify the root cause of your mouse infestation and quickly seal any gaps, holes, and cracks. They will also exterminate rodents that have already infiltrated your property, protecting your and your family’s health and safety.

Other Ways to Prevent Mice From Entering Your Property

Holes and other entry points are the most common way mice access your house. However, these rodents are more likely to get into your property if you:

  • Leave food and water around
  • You have excess moisture or humidity in your home
  • You don’t clean your home very often
  • You have lots of clutter on your property, such as items on the floor and empty boxes

In all of these circumstances, a pest control expert can help. Again, they will identify what’s causing your infestation and solve it using the latest tools and technologies. For example, professionals can fix leaky pipes or faucets that allow water to accumulate in your property, which can attract mice and other rodents.

Troy inspected my home carefully, made a recommendation, gave me a bid and did the work competently. He explained the termite life cycle n how the pesticide treatment worked. He indicated they may swarm again but after 90 days all evidence of live termites should be gone. He explained his warranty n yearly inspection.

Control or Inspect for Termites I was deeply impressed by the expertise and professionalism of Troy and Jeff. They have great knowledge about the biology and behavior of termites as well as years of experience working with residential customers. They knew exactly what needed to be done, were on time, worked hard, and patiently answered any questions I had. Having them do the job gave me great confidence that my pest problem will be promptly resolved.

Troy is the best! As realtors, we work with Pest Inspectors a LOT and have had issues with multiple companies being wrong or missing some sort of infestation. Troy is the ONLY guy we can always trust will do an amazing job. He is quick to respond and usually can get the job done very quickly! We really appreciate you!

Look no further. They offer free initial inspections. Robert from Pest Shield came out and quickly developed a plan to solve our yellow jacket problem. His advice provided quick and complete eradication of the yellow jackets and a plan for any future concern. Pest Shield offered the honest and pressure free service we appreciate. Pest Shield is now our “go to” for any future pest control issue.

Great service, called them about an issue I was having with yellow jackets flying in and out of the siding of my house, Troy came out the very next day and assessed the situation and got the problem fixed, he even checked in a couple days later to make sure the yellow jackets were not coming back. I would highly recommend them for the super quick service they provided and the fact that they check up on their work. Thanks again
