How to Mouse-Proof Your House and Keep Rodents Out for Good

As the weather cools, mice and other rodents begin searching for a warm, safe place to settle. And most often, the best option is inside your home. Once inside, these pests can chew wires, contaminate food, and leave behind droppings that can pose a health risk to your family. That's why mouse-proofing your home is so crucial.

At Alder Pest Control, we know just how sneaky these pests can be. Let's walk through practical steps for rodent-proofing a house and keeping unwanted critters out of your home.


Why Mouse Proofing Your House Matters

Mice may look small and harmless, but they cause significant problems:

  • Health Risks: Mice can spread salmonella, hantavirus, and other diseases.

  • Property Damage: Rodents chew insulation, wood, and electrical wiring, costing hundreds, if not thousands, in damage.

  • Fast Infestations: A single pair of mice can multiply into dozens within weeks.

Bottom line: Mouse-proofing your house before rodents move in is much easier than trying to get rid of an infestation later.


Identifying Signs of Rodent Infestations

Spotting the early warning signs of a rodent infestation is key to keeping your home rodent-free. Watch for these telltale signs:

  • Droppings around baseboards, pantries, or hidden corners

  • Gnaw marks on wood, wires, or furniture

  • Shredded materials like paper or fabric used for nesting

  • Musky odors that indicate rodent activity

  • Scratching or scurrying noises, especially at night

When inspecting your home, pay close attention to:

  • Small holes or gaps around exterior doors and garage doors

  • Openings in attic vents or crawl spaces

  • Even the tiniest cracks, since rodents can squeeze through surprisingly small spaces

By staying alert to these signs and sealing off entry points, you can prevent mice and other rodents from establishing an infestation.


How to Rodent-Proof Your Home: 5 Simple Steps

Follow these steps to effectively rodent-proof your home:

1. Seal Entry Points

Rodents can squeeze through holes as small as a dime. So it's crucial to inspect doors, windows, vents, your foundation, and crawl spaces, and seal all gaps, cracks, and crevices.

You can use steel wool and caulk to block gaps, and cover holes, vents, and openings with metal mesh or wire mesh. For larger holes, sheet metal is an effective solution. Apply weather stripping around doors and windows to ensure a tight seal.

2. Declutter & Organize

Cardboard boxes, piles of clothing, and storage areas are perfect nesting spots. Keep storage areas tidy and elevated, and use storage containers with tight-fitting lids to store food and other items.

3. Remove Attractants

One of the most effective ways to prevent rodents from invading your home is by removing the things that attract them to your home in the first place. Rodents are always on the lookout for easy access to food and shelter. To limit that access, store all food items—including dry foods and pet food—in tightly sealed glass or metal containers. Clean up crumbs and spills right away, and never leave food out overnight. By keeping your home clean and removing attractants, you make it much less appealing for rodents.

4. Exterior Rodent Proofing

Protecting your home starts from the outside. Begin by thoroughly inspecting the exterior, including the roofline, for any gaps, open vents, or other potential access points that could allow rodents to enter.

Keep your yard tidy by removing debris and clutter that can create hiding spots for rodents. Thin out plantings and keep bushes and trees trimmed away from your home to reduce potential nesting sites. Ensure garbage bins have secure lids or tight-fitting lids, and keep them away from the house. Clean up fallen fruit in the yard and place bird feeders away from the house to reduce attractants. By focusing on exterior rodent proofing, you can prevent mice and other rodents from entering your property and reduce the risk of a mouse infestation.

5. Call in the Pros

DIY measures help, but for complete peace of mind, professional mouse proofing a home ensures rodents don't stand a chance. At Alder Pest Control in Arkansas, we use advanced materials and methods to ensure your home is truly rodent-proof.
