GROUND SQUIRREL CONTROL ACROSS SOUTHERN CALIFORNIA

California ground squirrels thrive in SoCal's year-round warm climate. Colonial animals that burrow on sunny slopes, they migrate from open space preserves into residential properties across all five counties. We serve 162 cities with pet-safe trapping.

## Why SoCal Has Year-Round Ground Squirrel Pressure

Southern California's extensive open space system — the Santa Monica Mountains, Puente Hills, San Gabriel Mountains, Chino Hills State Park, Irvine Ranch — sustains massive ground squirrel populations on protected sunny slopes. These colonies can never be eliminated from protected land. When colony populations reach capacity, squirrels disperse into adjacent residential neighborhoods.

SoCal's mild climate means ground squirrels are active year-round with no true hibernation. Colonial burrowing undermines foundations, sidewalks, pool decking, and retaining walls. Ground squirrels also carry fleas that can transmit plague.

## Frequently Asked Questions

**How much does ground squirrel control cost?**

Starting at $325 for initial colony treatment. Monthly from $65, quarterly from $175.

**Are ground squirrels dangerous?**

Yes. Beyond property damage, California ground squirrels carry fleas that can transmit plague.

**Is ground squirrel control safe for pets?**

Yes. Pet-safe trapping methods. No poisons on residential properties.

**Do you serve all of Southern California?**

Yes — 162 cities across LA, OC, Riverside, San Bernardino, and Ventura counties.

**What is the difference between ground squirrels and tree squirrels?**

Ground squirrels burrow underground in colonies. Tree squirrels climb trees and nest above ground. We control ground squirrels only.

## SoCal Counties Ranked by GS Pressure

**1. San Bernardino County** — Chino Hills State Park (14,000 acres), San Bernardino Mountains foothills, and former dairy/agricultural land create the most extensive colony habitat in SoCal. Rancho Cucamonga, Upland, and Yucaipa see the heaviest residential colony pressure.

**2. Los Angeles County** — Santa Monica Mountains, Puente Hills, San Gabriel Mountains, and Palos Verdes Peninsula all sustain permanent colonies adjacent to residential communities. The sheer population density of LA means more properties are affected.

**3. Orange County** — Irvine Ranch open space preserves, Chino Hills, and Aliso-Wood Canyons create colony reservoirs that feed into master-planned communities.

**4. Riverside County** — Jurupa Mountains, Cleveland National Forest, and Santa Rosa Plateau harbor colonies that migrate into Corona, Riverside, and Jurupa Valley.

**5. Ventura County** — Conejo Valley and Santa Monica Mountains sustain colonies in Thousand Oaks, Simi Valley, and Moorpark.

## How Ground Squirrels Differ from Gophers

Ground squirrels are colonial above-ground foragers — they live in groups of 10-30, forage openly during daylight, and create visible burrow entrances. Gophers are solitary underground animals that rarely surface and create sealed tunnel systems. This behavioral difference matters for control: GS colonies require targeting multiple animals across a visible territory, while gopher control focuses on locating underground tunnel systems.

## Plague Risk from Ground Squirrel Fleas

California ground squirrels carry fleas that can transmit plague (Yersinia pestis). While human plague cases are rare in SoCal, animal cases are regularly detected in foothill communities. Orange County, Los Angeles County, and San Bernardino County health departments actively monitor ground squirrel flea populations for plague indicators. Properties with active GS colonies near children and pets should prioritize professional removal.

## Why GS Populations Grow Faster Than Gophers

Ground squirrels produce larger litters (5-11 pups vs 3-6 for gophers) and reach reproductive maturity faster. A colony of 10 squirrels can grow to 50+ in a single year if uncontrolled. This explosive reproduction is why early intervention is critical — a small colony today becomes a major infestation by next season.

## One-Time vs Monthly Service

One-time colony treatment ($325+) eliminates current residents. But for properties adjacent to open space, new squirrels can recolonize within weeks. Monthly service ($65/month) intercepts new arrivals before they establish breeding colonies — typically the most cost-effective approach for open-space-adjacent properties.
