How to Fill Chipmunk Holes

To effectively fill chipmunk holes and prevent further infestations in your home, follow these methods:

  • Locate and Seal Burrows: Observe for indications of chipmunk activity, such as piles of soil or damaged plants, to find their burrows. Once found, seal the entrances with suitable materials like concrete, chalk or mesh wire.
  • Use Coarse Sand: Fill the holes with coarse sand utilizing a funnel to ensure it reaches deep into the burrow. This will stop chipmunks from reopening the hole and creating new burrows.
  • Trap and Relocate: Consider catching and relocating chipmunks before filling their holes for a lasting solution. Look for humane traps that won’t harm the chipmunks.
  • Regularly Check for New Holes: Make it a habit to regularly inspect your yard for new chipmunk holes. If you spot any, fill them immediately to prevent further infestations.
  • Avoid Poison Pellets: Refrain from using poison pellets as they can harm other animals and may not effectively solve the problem.

In addition to these methods, it is important to eliminate possible food sources for chipmunks, such as bird feeders or gardens. Keep your yard tidy and free of debris, and prune back any overgrown vegetation that can provide shelter for chipmunks.

It is also beneficial to install barriers around potential entry points into your home, such as vents or gaps in the foundation. This will prevent chipmunks from entering and causing damage.

Steps for Filling a Chipmunk Hole

  • Locate and Seal Existing Burrows: The first step is to find any existing chipmunk burrows on your property. These are typically found under rocks, logs, or in piles of debris. Once you locate them, seal them with wire mesh or hardware cloth to prevent the chipmunks from returning.
  • Fill Holes with Coarse Sand: Simply filling the hole with dirt may not be enough as chipmunks can easily reclaim and reopen it. Instead, use coarse sand or fine gravel to fill the hole. This not only blocks the entrance but also improves drainage and makes it difficult for chipmunks to dig through.
  • Consider Used Cat Litter: Another effective method is to use used cat litter to fill the holes. The strong scent and texture of the litter make it challenging for chipmunks to excavate, acting as a natural repellent.
  • Use Underground Fencing: For a more long-term solution, install an underground fence made of privacy or mesh fencing. This should extend at least eight inches below ground level to prevent any burrowing animals from entering your property.
  • Avoid Poisoning Methods: It’s essential to note that using poison pellets or attempting to make the holes look like they belong to a predator are not effective solutions and can have harmful consequences for other animals and plants.

  • Regularly Check for New Holes: Keep an eye out for any new chipmunk holes on your property and fill them immediately before they become a problem.
  • Use Deterrent Methods: Along with filling holes, consider using deterrent methods like electronic repellents or motion-activated sprayers to keep chipmunks away from your property.

Why Fill Chipmunk Holes?

Filling chipmunk holes has numerous benefits and is a crucial step in pest control for any household. These advantages and the significance of this task include:

  • Preventing further damage to lawns and gardens – Chipmunks are known for their mischief and can cause frustration for homeowners who take pride in their lawn’s appearance. By filling chipmunk holes, you can collapse underground tunnels and prevent them from causing more damage to your property.
  • Maintaining a safe yard – While having a family of chipmunks in the yard may seem harmless, they can destroy flowerbeds, create uneven surfaces, and even create potential tripping hazards. Filling chipmunk holes can help keep your yard safe for your family and guests.
  • Eliminating potential entry points for other pests – Chipmunk holes can vary in depth and extend up to 30 feet, providing easy access points for other pests such as mice, rats, and insects. Filling these holes prevents other pests from entering your property.
  • Long-term pest control – Simply filling chipmunk holes is not enough to permanently eliminate their presence. Exclusion or relocation methods must be used for long-term pest control. Filling the holes is just one step in this process.
  • Simple steps for filling chipmunk holes – The process of filling chipmunk holes is relatively simple and can be done using a lawn roller, plugging entrance and exit holes with soil, and spreading topsoil over the surface. This makes it an easy DIY solution for homeowners.
  • Alternative methods – Other methods such as using gravel or concrete may be more effective in preventing chipmunks from burrowing into yards. Deterrent measures like fencing or natural repellents can also be implemented to make the yard less attractive to chipmunks.
  • Protecting against other burrowing animals – Other animals that dig holes in yards include squirrels, voles, moles, and groundhogs.

Rounded shape Unlike other animal burrows, chipmunk holes are typically more circular in shape.
Frequent use If you see a well-worn path leading into the hole, it is likely being used by a chipmunk.
Behavioral Indicators How to Identify
Active during daytime hours If you notice holes appearing overnight, it is less likely to be caused by a chipmunk.
Multiple burrows within their territory If there are multiple holes in one area, they are likely connected and part of a chipmunk’s burrow system.

To effectively identify a chipmunk hole in your yard, keep an eye out for its physical characteristics such as its small size, circular shape, dirt mound, and worn path. In addition, behavioral clues like daytime activity and the presence of multiple burrows within a territory can also help with identification.

For homeowners, it is important to be able to spot chipmunk holes in order to prevent further damage to their lawns and gardens. By understanding the physical and behavioral indicators of a chipmunk hole, homeowners can take necessary measures to avoid any potential damage. In addition, keeping an eye out for multiple burrows in one area can also indicate the presence of a chipmunk’s burrow system.

It is worth noting that chipmunks are diurnal creatures, meaning they are active during the day and sleep at night. This is why if you notice new holes appearing overnight, it is less likely to be caused by a chipmunk. Furthermore, chipmunks tend to have multiple burrows within their territory for different purposes, such as storing food or escaping predators. Therefore, if you see multiple holes in one area, they are likely connected and part of a chipmunk’s burrow system.

Understanding Chipmunk Holes

Chipmunk holes, also known as burrows, can be identified by a variety of shared traits. These features include their size, shape, and placement.

  • Size: Chipmunk burrows are commonly around 2-3 inches in diameter, making them smaller than other animal burrows like those made by groundhogs or moles. They are also level with the ground, without any visible piles of dirt surrounding the entrance.
  • Shape: A chipmunk’s home has numerous entrances, some of which may be obstructed by leaves or sticks. They also have “plunge holes,” which are tunnels that go straight down into the earth.
  • Location: These critters often set up their burrows near trees or shrubs, as these provide shelter for the chipmunks to hide in. They may also be found near sources of food, such as bird feeders or gardens.

Along with these physical characteristics, there are also behavioral cues that can help identify a chipmunk hole. These include:

  • Daytime activity: Unlike other burrowing animals that tend to be active at night, chipmunks are daytime creatures and can frequently be seen scurrying around during the day.
  • Multiple burrows in one territory: Each chipmunk has its own individual burrow, and they will defend their territory from other chipmunks. This means that if there are multiple holes in your yard, they are likely being used by different chipmunks.

Why Fill Chipmunk Holes?

It is crucial to address the issue of filling chipmunk holes in your yard or garden for various reasons. Primarily, it helps prevent these bothersome rodents from continuously digging and causing damage to your property. Chipmunks are notorious for creating intricate networks of tunnels and burrows, which can weaken the ground, resulting in sinkholes or even harm to structures such as patios or decks.

Understanding Chipmunk Holes

Chipmunk holes can be identified by several key characteristics. First, they are small in size, typically measuring only 1-2 inches in diameter. Additionally, they are shallow in depth, usually only a few inches deep. These holes can often be found near trees or buildings, as chipmunks prefer to dig their burrows near structures or gardens.

One of the main differences between chipmunk holes and other animal burrows is their size and depth. Chipmunk holes are smaller and shallower compared to burrows made by other animals. They also differ in location, as chipmunks tend to dig near structures or gardens, while other animals typically dig in open fields.

Another distinct characteristic of chipmunk holes is their entrance shape. These holes have a distinctive U-shape, making them easily recognizable. In contrast, other animals tend to create round entrances for their burrows.

Finally, the presence of nearby food caches can also indicate the presence of chipmunk holes. Chipmunks will often have piles of stored food near their burrow entrances, while other animals may not exhibit this behavior.


In conclusion, filling chipmunk holes is a crucial task in maintaining the beauty and safety of your outdoor space. Not only does it prevent further damage to your lawn and gardens, but it also eliminates potential entry points for other pests.

By following the simple steps outlined in this blog post, you can effectively fill chipmunk holes and safeguard your home from these pesky burrowing animals. Remember to regularly check for new holes and use deterrent methods to keep chipmunks at bay.
