Let’s face it, chipmunk holes under your home foundation can be a real nuisance. Chipmunks, despite being cute critters and fun to watch on their scavenges for food, can quickly take over an area or create dangerous crevices that weaken the stability of the house’s underlying structure. But don’t worry – there are plenty of simple solutions to combating this unfavorable problem! In this blog post, we will go through some effective strategies for sealing these chipmunk holes so you can get back to the peace of mind knowing your home is safe from any damage caused by local nature lovers. Let’s get started!

Identify the source of the problem – look for tunnels and holes around the foundation to determine how extensive the issue is

If you’re experiencing foundation issues, it’s important to identify the source of the problem before attempting any repairs. One way to do this is to carefully inspect the area around the foundation for signs of tunnels and holes. These can be indicative of pests, such as rodents or termites, that have been gnawing away at the foundation and weakening its integrity. By determining the extent and severity of the issue, you can better plan for repairs and prevent further damage from occurring. While it may take a bit of time and effort to investigate the foundation thoroughly, it’s well worth it to ensure the safety and stability of your home.

Take preventive steps – trim trees, bushes, and vegetation that provide cover for chipmunks; set up traps to capture any stragglers

Chipmunks can be cute and entertaining, but they can wreak havoc in your yard and home. To prevent them from taking over, it’s important to take proactive measures. Trimming trees, bushes, and other vegetation that provide cover for them is a good place to start. This also helps to limit access to your home and any potential food sources. Additionally, setting up traps can be an effective solution for capturing any stragglers. Remember, the key is to take action before chipmunks become a serious problem. By being proactive, you can keep these cute critters at bay and maintain a peaceful yard.

Fill in all existing holes with a mixture of mortar, soil, and sand

Have you ever wondered how to address those unsightly holes in your outdoor living space? Look no further than a mixture of mortar, soil, and sand! This magical concoction can be used to fill in any existing holes and seamlessly blend in with the surrounding area. Don’t let those holes bring down the aesthetic of your patio or garden – take matters into your own hands with this simple DIY solution. Plus, with the added benefit of using natural materials, you can feel good about your eco-friendly approach to repairing your outdoor space.

Use metal screens or hardware cloth to seal off potential entry points

Securing your property from unwanted intruders is essential, especially when it comes to pests and critters. One of the most effective ways to deter them from entering your home is to use metal screens or hardware cloth to seal off potential entry points. These screens are durable and can withstand harsh weather conditions, making them an ideal solution for keeping pests out. Hardware cloth is also an excellent option for covering vents and other openings where small animals or insects can enter. By preventing them from entering your home, you can minimize the risk of property damage and keep your family safe from potential health hazards associated with these pests.

Set out granular repellents to discourage future chipmunk activity near your foundation

You may have noticed some pesky chipmunks setting up shop near your home, but fear not! With a few well-placed granular repellents, you can discourage these critters from wreaking havoc on your foundation. These repellents work by emitting a scent that chipmunks find unpleasant, causing them to steer clear of the area. It’s a non-toxic and safe solution, making it a great alternative to harsh chemicals. Just be sure to follow the instructions carefully and set out the repellents strategically to see the best results. With a little effort, you can protect your home and keep those chipmunks at bay.

Monitor your work regularly – check for new holes and spots of digging on a regular basis

As a responsible person, it is essential to stay alert and monitor your work regularly. Every project has its fair share of challenges and obstacles that may arise unexpectedly. In particular, new holes and spots of digging could occur even if you’ve planned everything accordingly. By keeping an eye out for any potential problems, you’re able to respond quickly and take the necessary measures to ensure that your project stays on track. Take the time to review your work regularly, and don’t get caught off guard by holes and digging that could bring the work to a crawl. By being vigilant, you’re able to catch problems early and keep your project moving forward smoothly.


In conclusion, chipmunk control requires identifying the source of the issue, implementing preventive steps, filling in holes and entry points with soil and mortar, using metal screens or hardware cloth to seal off potential entry points, setting out granular repellents to discourage future activity, and monitoring your work regularly. By following these simple guidelines, you can keep your home free from pesky chipmunks and reduce the amount of damage they can cause. While it may seem daunting at first, tackling this problem in stages makes it much more manageable. It may take some time and effort on your part to make sure your foundation is well-protected, but it is definitely worth it in the long run.
