Ground Squirrel Control in Pasadena, CA

Pasadena, CALIFORNIA

Pasadena yards—especially surrounding Pasadena City Hall on North Garfield Avenue—often attract ground squirrel colonies.

Pasadena yards and open areas—especially surrounding Pasadena City Hall on North Garfield 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 Pasadena

• 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 Pasadena Has Ground Squirrel Problems

Pasadena sits at the base of the San Gabriel Mountains where the foothill grasslands and rocky slopes above the city sustain large California ground squirrel colonies. The Arroyo Seco corridor running through western Pasadena provides additional open space habitat — the Rose Bowl area's 90+ acres of open turf and the Hahamongna Watershed Park above the Rose Bowl sustain some of the densest ground squirrel populations in the San Gabriel Valley.

Altadena, directly above Pasadena, has even heavier colony pressure from immediate mountain adjacency. Ground squirrels from Altadena foothill colonies migrate south into upper Pasadena neighborhoods, establishing new colonies in residential yards, along property lines, and under structures.

The San Rafael Hills between Pasadena and Glendale provide additional elevated terrain with sunny south-facing slopes that ground squirrel colonies prefer for burrow establishment.
