How to Get Rid of Ground Squirrels: What Actually Works

California ground squirrels are one of the most persistent yard pests in Southern California. Unlike gophers, they're active above ground during the day, making their damage very visible — but also making them harder to fully eliminate without the right approach.

Why Ground Squirrels Are Hard to Control

Ground squirrels live in colonies with complex burrow systems that can extend 6 feet deep and 30 feet horizontally. A single colony can have dozens of animals, and squirrels are highly mobile — new squirrels from neighboring properties will move into vacated burrows within days if the population isn't continuously managed.

In Southern California, ground squirrels are active nearly year-round, with peak activity in spring and early summer when juveniles disperse from their birth colonies.

Common Ground Squirrel Control Methods

• Trapping: Cage traps or kill traps placed at burrow entrances. The most effective and pet-safe method.
• Rodenticide bait: Anticoagulant or zinc phosphide baits placed in bait stations. Effective but dangerous to pets, raptors, and wildlife through secondary poisoning.
• Burrow fumigation: Gas cartridges or aluminum phosphide used to fumigate burrows. Limited effectiveness due to extensive tunnel systems.
• Exclusion: Hardware cloth barriers buried 18-24 inches deep around garden beds. Effective for small areas but impractical for large properties.
• Habitat modification: Removing brush piles, rock walls, and other shelter reduces habitat attractiveness but does not eliminate existing colonies.

Pet-Safe Ground Squirrel Control

If you have dogs or cats, rodenticide bait is not a safe option. Ground squirrels killed by anticoagulant bait retain the poison in their bodies — a dog or cat that catches and eats a poisoned squirrel can suffer secondary poisoning, which is often fatal without emergency veterinary treatment.

Mechanical trapping is the only method that eliminates squirrels without any poison risk. Gopher Guys uses professional-grade traps that are set and checked by trained technicians, removing squirrels without placing any toxic substance in your yard.

What to Expect From Professional Treatment

Ground squirrel control typically requires multiple service visits. Unlike gophers, which are solitary, squirrel colonies require ongoing trapping to reduce the population to a manageable level. Gopher Guys offers both one-time and recurring service plans for ground squirrel control across Los Angeles, Orange, Riverside, and San Bernardino Counties.

Gopher Guys serves all of Southern California including Los Angeles County, Orange County, Riverside County, and San Bernardino County.
