Professional California ground squirrel removal using trapping only. Safe for dogs, cats, horses, chickens, and children. 60-day guarantee.
The California ground squirrel (Otospermophilus beecheyi) is the most structurally damaging rodent in Southern California. Unlike gophers, ground squirrels live in colonies — what appears to be a single burrow entrance is typically part of a larger underground colony that may include dozens of animals. Left untreated, ground squirrel colonies undermine foundations, retaining walls, slopes, and drainage systems over time.
Ground squirrels are diurnal — active above ground during the day — which means homeowners can observe them directly. This visibility makes ground squirrels seem like a manageable problem. In practice, their colony structure means that removing a few visible individuals has little impact on the overall population. Professional colony management requires systematic trapping over an extended period.
The technician surveys the property to identify all active burrow systems, estimate colony size, and map squirrel activity areas. Ground squirrel colonies can be much larger than the visible burrow entrances suggest — accurate assessment is essential for effective treatment planning.
Traps are positioned at active burrow entrances and along established squirrel movement routes. Both live traps and lethal traps are used depending on the location and property type. All trap locations are flagged and documented.
Ground squirrel colony elimination takes longer than single-gopher removal — colonies require systematic reduction over multiple visits. The technician returns regularly until squirrel activity stops completely, backed by a 60-day guarantee.
California ground squirrels create burrow entrances that are typically 3 to 4 inches in diameter with loose soil pushed to one side. Multiple entrances close together indicate a colony rather than a single animal. Unlike gopher mounds, squirrel burrow entrances are open — not plugged. You'll typically see the squirrels themselves during daylight hours, often perched on rocks, fence posts, or burrow mounds.
Beyond visible squirrels, look for: soft or spongy areas in lawn indicating tunnel collapse, soil subsidence near retaining walls or foundations, erosion channels at slope edges, and undermined concrete slabs or hardscape.

A property with 5 visible burrow entrances may have 15 to 25 squirrels underground. Colony size is one of the key factors the technician assesses during the initial inspection — larger colonies require more visits and extended treatment periods.
Yes — this is one of the most serious risks from established ground squirrel colonies. Deep burrow systems that run under foundations, retaining walls, or slopes create voids that lead to settling and structural damage over time. Slope failures from ground squirrel burrowing are documented across Southern California's hillside communities. Early treatment is significantly less expensive than structural repair.
Properties bordering open space may see re-colonization from adjacent wildland areas over time. A 60-day guarantee covers return visits within 60 days of service completion. For properties in high-pressure areas, recurring preventive service is often the most cost-effective long-term approach.
Yes — trapping is the only ground squirrel control method that is safe for horses. Ground squirrel bait is toxic to horses and should never be used on any equine property. Traps are set at burrow entrances and in areas horses cannot access, and contain no toxic substances of any kind.
