The Ultimate Guide to California Ground Squirrel Control

Ground squirrels are a common nuisance in both agricultural and suburban areas across North America. These pests wreak havoc by digging extensive squirrel burrows, devouring crops, and damaging landscaping.

In California, where conditions are ideal for their survival and reproduction, their prevalence is especially notable. While these critters may seem harmless at first glance, their ability to multiply quickly and adapt to various environments makes them a formidable challenge for property owners.

This guide will equip you with actionable advice and effective solutions for managing ground squirrel infestations. Whether you’re dealing with a minor ground squirrel problem or a widespread issue, we’ll provide you with the tools needed to protect your property while adhering to legal and ethical practices.

The Ultimate Guide to Ground Squirrel Control

Understanding California Ground Squirrels: The Problem

Before you can effectively tackle a ground squirrel problem, it’s important to understand their behavior and what makes your property attractive to them.

Ground squirrels are small, burrowing rodents widely distributed across North America. They’re particularly prevalent in agricultural and suburban areas, where their adaptability and rapid reproduction make them a persistent challenge for property owners. Certain species, such as California ground squirrels, thrive in regions with mild climates and abundant food sources, leading to significant infestations in some areas.

Ground Squirrel Behavior and Habitat

Ground squirrels are diurnal rodents that live in colonies and create extensive burrows systems. Ground squirrel burrows can stretch up to 30 feet in length and reach depths of four feet below the surface. They prefer open areas with loose soil for easy digging, often found near gardens, farms, or parks.

Their social behavior includes standing upright as a lookout and engaging in "kissing" encounters when interacting with others in their colony. Seasonal patterns also play a role in their activity levels. Ground squirrels hibernate during colder months and emerge in spring for mating season.

Common Problems Caused by Ground Squirrels

These seemingly cute critters can cause surprising damage. Here’s what you might be dealing with:

  • Lawn and Garden Damage: Ground squirrels create unsightly mounds of soil when they burrow under lawns and gardens to eat plants, fruits, seeds, and berries.
  • Property Damage: Burrowing can undermine foundations, irrigation systems, and sprinkler heads, leading to costly repairs.
  • Health Risks: Ground squirrels can spread diseases like plague and tularemia. Their presence may also attract predators, such as snakes or hawks, posing additional risks to pets or livestock.

While complete elimination of ground squirrels may not be feasible or necessary, managing their populations is essential to minimizing negative impacts on humans and property. If you have a rodent problem, understanding these issues is the first step toward effective pest management.

Legal Considerations for Ground Squirrel Control in the Target Region

Before you start any ground squirrel control efforts, it’s essential to understand the legal framework surrounding these activities. Regulations vary across regions, and compliance is crucial to avoid penalties and ensure ethical treatment of wildlife.

Wildlife Protection Laws and Regulations

Here’s a general overview of what you need to know:

  • United States: Ground squirrel control regulations differ by state. For example, in California, property owners do not need a permit to trap California ground squirrels that are causing property damage. In Idaho, most ground squirrels are considered unprotected and can be controlled without a permit on private property. However, in Alabama and Indiana, you may need a permit for trapping or relocating squirrels.
  • Canada: As of March 4, 2025, strychnine was used to control Richardson's ground squirrels due to its risk to non-target species.

Important Considerations

  • Licensing and Permits: Some states require specific licenses or permits for trapping or relocating squirrels, while others allow property owners to act without one.
  • Ethical and Humane Treatment: Many regulations emphasize humane practices, such as using live traps and checking them regularly to reduce animal suffering.

Ground Squirrel Control Methods: Effective Strategies

Effectively managing ground squirrel populations may require lethal control techniques where legally permissible. Control methods should be tailored to address varying levels of infestation and environmental conditions, ensuring property owners can protect their land while adhering to ethical practices.

Lethal Control Methods (if applicable and legal)

In severe infestations, lethal control may be necessary if populations threaten property or public health.

Self-resetting traps, like those from Automatic Trap, are often preferred for their efficiency and minimal risk to non-target species. These traps automatically reset, targeting only squirrels while reducing the risk to pets or wildlife.

Body-gripping traps (e.g., Conibear traps) can cause quick kills but pose a significant risk to non-target animals, including pets and children. These traps should always be used with caution and monitored regularly.

Rodenticides (e.g., zinc phosphide) and burrow fumigants are effective but require careful application to limit exposure to non-target species. These methods may not be widely supported due to their potential environmental and ethical concerns.

Unlike traditional traps that require manual resets after each capture, self-resetting traps are equipped with mechanisms that allow them to operate continuously. Powered by CO2 cartridges, these traps reset automatically, making them highly efficient for areas with frequent ground squirrel activity.

Why Self-Resetting Traps Are the Best Choice

Self-resetting traps offer numerous advantages over traditional trapping methods, making them the ideal choice for controlling ground squirrel populations. One key benefit is its humane design, engineered to deliver a quick and painless kill.

Efficiency is another major advantage. Unlike manual traps that require frequent attention, automatic models can self-reset after each capture, handling multiple squirrels without intervention.

Automated features such as baiting, capturing, resetting, and releasing make these traps a cost-effective solution in the long run. Property owners no longer need to invest in multiple traps or spend hours monitoring and resetting devices.

Best Practices for Long-Term Ground Squirrel Control

Effective long-term management of ground squirrels requires a comprehensive approach that combines preventive measures with targeted control methods. By understanding the behavior and life cycle of these pests, property owners can implement strategies that discourage infestations and maintain a squirrel-free environment throughout the year.

Ongoing Prevention

There are various ways to reduce the interest of ground squirrels in your property. Through regular inspections, check for burrowing and feeding areas, and close entry points with soil or gravel to prevent reoccupation. Discourage return by managing the environment: remove debris piles or tall grass that provide shelter for burrowing activities, keep grass stands over 15 cm, and encourage natural predators with trees or nesting platforms.

You can also make your property less attractive to ground squirrels by using deterrents. Install fencing made of hardware cloth or mesh with small openings to block access to vulnerable areas. Bury fencing at least 12 inches underground and extend it 18 inches above ground to deter climbing.

Proactively clean up fallen fruits, nuts, seeds, or unprotected bird feeders regularly, store pet food in sealed containers, and harvest ripe fruits promptly. Plant mint or marigolds around gardens, or apply sprays made from chili peppers or predator urine around gardens and burrow entrances to act as natural repellents.

Seasonal Considerations

Ground squirrel behavior changes throughout the year, and understanding these patterns is key to effective control. The timing of hibernation and emergence varies by age and gender, which affects when control efforts are most successful.

In spring, squirrels emerge from hibernation, typically between mid-March and mid-April. This is the best time for early intervention, as females are pregnant but young have not yet emerged.

During summer and fall, ground squirrels focus on feeding, especially on seeds. This makes baiting with treated grain an ideal method during these months. First-generation anticoagulant grain baits are especially effective in spring when squirrels are highly active.

To maximize results, adjust your methods seasonally. Use trapping or shooting in early spring when populations are smaller, and transition to baiting as activity increases later in the year.
