Ground Squirrel Control in San Dimas, CA

San Dimas, CALIFORNIA

San Dimas yards—especially surrounding San Dimas City Hall on East Bonita Avenue—often attract ground squirrel colonies.

San Dimas yards and open areas—especially surrounding San Dimas City Hall on East Bonita Avenue—often attract ground squirrel colonies due to favorable burrowing conditions and available food sources.

Ground squirrels are active above ground and create visible burrow systems with multiple entrance holes. Unlike gophers, these rodents forage openly during daylight hours and can quickly establish colonies on residential and commercial properties. Their burrowing destabilizes soil, damages hardscapes, and creates trip hazards. Ground squirrel populations expand rapidly when left unmanaged, making early intervention critical for effective control.

Common Ground Squirrel Problems in San Dimas

• Multiple burrow openings across the property
• Soil erosion and ground instability
• Damage to patios, walkways, and retaining walls
• Risk to pets from burrow encounters

How Ground Squirrel Control Works

Our technicians assess the property to determine the most effective treatment approach. Ground squirrel control may involve trapping, carbon monoxide treatment, or a combination of both methods based on the technician's professional assessment of site conditions and squirrel activity levels. Treatment continues until active squirrel presence is reduced on the property. Because ground squirrels can travel between properties, service focuses on addressing current activity rather than providing a long-term guarantee.

Why Ground Squirrels Are Different

Unlike gophers and moles that remain underground, ground squirrels are highly mobile and can move freely between neighboring properties. This mobility means that new squirrels may enter your property even after successful treatment of existing colonies. Our service targets active infestations and reduces current ground squirrel populations on your property.

## Why San Dimas Has Ground Squirrel Problems

Frank G Bonelli Regional Park sustains one of the largest ground squirrel populations in the San Gabriel Valley. The park's open grassland, sunny slopes, and lack of predator control create ideal ground squirrel habitat. These park squirrels migrate into adjacent San Dimas residential properties, establishing colonies in yards, along property lines, and in hillside landscaping.

Puddingstone Reservoir area and Via Verde hillside properties face the most direct migration from park populations. The San Gabriel Mountains foothills above San Dimas add additional ground squirrel habitat where colonies establish on sunny, south-facing slopes and expand downhill into residential areas.

Ground squirrels differ from gophers in a key way — they are colonial animals that live in groups, often with multiple burrow entrances. A single colony can have 10-30 members, making them more visible than solitary gophers but equally damaging to landscaping and structures.
