How to Seal a Ground Squirrel Burrow: A Comprehensive Guide

How do you plug a ground squirrel hole? The best method for plugging a ground squirrel hole involves a multi-pronged approach including temporary deterrents, burrow collapsing, and ultimately, filling the hole with materials unattractive to the squirrels like gravel and dirt, followed by preventative measures to discourage re-infestation.

Ground squirrels, those seemingly harmless rodents, can wreak havoc on gardens, landscapes, and even building foundations. Their extensive burrow systems undermine the soil, creating hazards for people and livestock. While lethal control methods exist, many homeowners and land managers prefer humane and sustainable solutions. Successfully plugging a ground squirrel hole isn’t simply about stuffing dirt into a burrow; it’s a strategic process that requires understanding ground squirrel behavior and employing appropriate techniques. This guide provides a comprehensive overview of how to effectively and humanely address ground squirrel burrows.

Understanding the Ground Squirrel Problem

Ground squirrels are opportunistic creatures. They are attracted to areas with readily available food sources, such as gardens, crops, and bird feeders. Their burrow systems provide shelter from predators and harsh weather. Before attempting to plug a hole, it’s crucial to understand the extent of the infestation. Are there multiple holes? Are there signs of recent activity, like fresh digging or droppings? Identifying entry and exit points is crucial for successful burrow management.

Choosing the Right Plugging Method

There isn’t a single “magic bullet” for plugging ground squirrel holes. The best approach often involves a combination of techniques. Here’s a breakdown of some effective methods:

Temporary Deterrents: These methods aim to discourage squirrels from using the burrow.
- Ammonia-soaked rags: Ground squirrels are sensitive to strong smells. Placing ammonia-soaked rags into the burrow entrance can temporarily deter them. Caution: This method should be used cautiously near plants.
- Commercial repellents: Several commercial repellents are available, often containing ingredients like castor oil or garlic. Follow the manufacturer’s instructions carefully.
- Motion-activated sprinklers: These can startle and discourage squirrels from frequenting the area.
Burrow Collapsing (Caution Required): If the burrow is near the surface and away from building foundations or valuable root systems, carefully collapsing the tunnel entrance can sometimes disrupt the squirrels. However, use caution as collapsing tunnels can create new problems.
Filling the Hole: This is the most crucial step and requires using materials that are difficult for squirrels to dig through.
- Gravel: This is an excellent base layer, as it is difficult for squirrels to excavate.
- Dirt: After the gravel, fill the remaining space with compacted dirt.
- Compaction: Use a tamper or your foot to firmly pack the dirt into the hole. This prevents the squirrels from easily re-opening the burrow.
Preventative Measures:
- Remove food sources: Secure garbage cans, clean up spilled birdseed, and protect gardens with fencing.
- Habitat Modification: Trim overgrown vegetation and remove brush piles that provide shelter for squirrels.
- Predator Encouragement: If feasible and safe, encourage natural predators like hawks, owls, and snakes (where appropriate) to frequent the area.

Step-by-Step Guide to Plugging a Ground Squirrel Hole

Observation: Identify all active burrow entrances. Look for signs of fresh digging or activity.
Deterrent (Optional): Consider using a temporary deterrent, like ammonia-soaked rags, before filling the hole.
Gravel Filling: Pour gravel into the hole until it is approximately two-thirds full.
Dirt Filling: Fill the remaining space with dirt.
Compaction: Firmly compact the dirt with a tamper or your foot.
Monitoring: Monitor the area for several days to see if the squirrels re-open the burrow. If they do, repeat the process.
Prevention: Implement preventative measures to discourage future infestations.

Common Mistakes to Avoid

Using only dirt: Ground squirrels can easily dig through loose dirt.
Not compacting the soil: Loose soil provides little resistance.
Ignoring other entry points: Failing to address all burrow entrances will render your efforts futile.
Neglecting preventative measures: Without preventative measures, the squirrels will likely return.
Plugging holes without confirming absence: You may trap and kill the animal inside. Use deterrents first.

How Long Does it Take to See Results?

The timeframe for seeing results varies depending on the severity of the infestation and the effectiveness of your methods. It may take several days or weeks to completely eliminate ground squirrels from your property. Persistence and consistent application of preventative measures are key.

Legal Considerations

Before implementing any control methods, check with your local wildlife agency to ensure that your actions comply with all applicable laws and regulations. Some areas may have restrictions on ground squirrel control.

Frequently Asked Questions (FAQs)

Is it cruel to plug a ground squirrel hole?

Plugging a ground squirrel hole can be perceived as cruel if done improperly. Ensure the animal has left the burrow before permanently sealing it by using temporary deterrents for several days. Plugging a hole with an animal inside will likely result in its death. Always prioritize humane methods.

What if the ground squirrel just digs another hole?

Ground squirrels are persistent. If they dig another hole, repeat the plugging process and focus on preventative measures. Identifying and addressing all potential entry points into your property is crucial. Consider fencing and removing food sources.

Will plugging the hole damage my lawn or garden?

If done carefully, plugging a ground squirrel hole should not significantly damage your lawn or garden. Avoid excessive digging or the use of harsh chemicals. Compact the soil properly to minimize disturbance.

Can I use expanding foam to plug the hole?

While expanding foam might seem like a quick fix, it’s not recommended. Ground squirrels can easily chew through it, and it poses an environmental hazard. It’s also difficult to remove if you change your mind.

Is it better to trap and relocate ground squirrels?

Relocating ground squirrels is generally not recommended. They often do not survive in new environments and may carry diseases. In many jurisdictions, relocation is illegal. It is generally preferable to focus on deterrents and habitat modification.

How can I keep ground squirrels out of my garden?

Protecting your garden requires a multi-faceted approach. Consider:

Fencing: Install a fence that extends at least 12 inches below ground.
Netting: Cover vulnerable plants with netting.
Repellents: Use commercial repellents specifically designed for ground squirrels.

What are the signs of a ground squirrel infestation?

Common signs include:

Visible burrows: These are typically 2-4 inches in diameter.
Fresh digging: Look for mounds of soil near burrow entrances.
Damage to plants: Ground squirrels may eat fruits, vegetables, and flowers.
Squirrel sightings: Observing ground squirrels in your yard is a clear indication of their presence.

What is the best time of year to plug ground squirrel holes?

The best time to plug ground squirrel holes is during the dormant season, typically late fall or winter, when the squirrels are less active. This reduces the risk of trapping animals inside the burrow.

Will poison work to get rid of ground squirrels?

While poison can be effective, it poses significant risks to non-target animals, including pets and wildlife. It is generally not recommended due to ethical and environmental concerns. Consider alternative methods first.

Are there any natural predators of ground squirrels?

Yes, ground squirrels have several natural predators, including:

Hawks
Owls
Snakes
Coyotes
Foxes

How deep are ground squirrel burrows?

Ground squirrel burrows can be quite extensive, often reaching depths of 5-10 feet or more. They can also extend horizontally for considerable distances.

How do I know if the hole is truly abandoned after plugging it?

After plugging the hole, monitor it closely for several days. If there is no sign of digging or activity, it is likely that the burrow is abandoned. However, ground squirrels can be surprisingly resourceful. Consider using a temporary deterrent for an extended period before permanently sealing the hole. Also observe for other holes in the area.
