What size hole can a chipmunk fit through?

Answered by Robert Flynn

Chipmunks are incredibly resourceful creatures when it comes to finding small spaces to squeeze through. They have the ability to fit through holes as small as two inches wide! This means that even the tiniest gaps or cracks in your siding could potentially become an entry point for these critters.

It’s important to be proactive in sealing up any holes or gaps you may find on the outside of your house to prevent chipmunks from entering. Here are a few methods you can use to cover these openings:

1. Caulk: One of the simplest and most effective ways to seal small cracks or holes is by using caulk. Choose a high-quality caulk that is suitable for outdoor use and apply it generously to fill in the gaps. Be sure to smooth it out for a neat and even finish.

2. Expandable construction foam: For larger gaps or holes, expandable construction foam can be a great solution. This foam expands to fill the space, creating a tight seal. Be cautious when using this method, as the foam can expand significantly and may require trimming once it has dried.

3. Concrete: If you have larger holes or gaps in your siding, using concrete can provide a durable and long-lasting solution. Mix up a small batch of concrete and carefully fill in the openings. Smooth it out and allow it to dry completely before painting or sealing.

Remember, it’s not just the size of the holes that you need to be concerned about. Chipmunks are skilled climbers and can also access your home through damaged or loose areas of your siding. So, don’t overlook any signs of wear or damage.

In addition to sealing up any holes or cracks, it’s also important to inspect your siding regularly for any signs of damage or deterioration. Repair or replace any damaged sections promptly to maintain the integrity of your home’s exterior.

Taking these preventive measures can go a long way in keeping chipmunks and other unwanted pests out of your home. By being proactive and sealing off potential entry points, you can ensure a pest-free living environment.
