Ground squirrels are a persistent pest problem throughout Southern California, and Corona is no exception. Located in Riverside County between the Santa Ana Mountains and the Inland Empire, Corona's mix of residential neighborhoods, open spaces, and agricultural areas creates an ideal habitat for ground squirrels. The region's warm, dry climate and abundance of landscaping, gardens, and irrigation systems provide both food sources and water—everything ground squirrels need to thrive year-round.
If you've noticed mounds of dirt in your yard, damage to plants and irrigation lines, or seen small striped squirrels darting across your property, you're dealing with a common Corona issue. Ground squirrels aren't just a nuisance; they can cause serious damage to your landscape, undermine foundations, and even compromise the integrity of retaining walls. Their burrowing activity can also create hazards for pets and people who step in holes unexpectedly.
Corona's suburban sprawl has created the perfect storm for ground squirrel populations. The city's many residential properties feature trees, shrubs, and maintained lawns that provide food and cover. Additionally, the prevalence of drip irrigation systems and mulched landscaping gives ground squirrels constant access to moisture and soft digging substrate. Younger developments on the outskirts of Corona, closer to open foothill areas, experience particularly heavy ground squirrel activity because they're positioned right at the interface between wild habitat and residential zones.
Ground squirrels are most active in spring and early summer when they're breeding and foraging for food to cache. However, in Corona's mild climate, they can remain active throughout much of the year, making year-round management important for prevention and control.
Controlling ground squirrels requires a multi-faceted approach. Exclusion is one of the most effective long-term strategies—removing food sources by securing garbage, cleaning up fallen fruit, and protecting vegetable gardens with fencing can make your property less attractive to squirrels. Hardware cloth barriers buried at least 12 inches deep can prevent burrowing near structures and garden beds.
Trapping is often necessary to reduce existing populations, but it requires knowledge of squirrel behavior and local regulations. Live trapping and relocation, lethal trapping, and other control methods each have pros and cons.

Prevention is always easier than dealing with an established population. Seal holes around utilities, remove brush piles, trim tree branches away from roofs, and maintain clear space around building foundations. If you're planning landscaping updates, consider xeriscaping with less palatable plants, which can deter ground squirrels while conserving water—an important consideration in Southern California.
The key to managing ground squirrels in Corona is early intervention and consistent prevention. Acting quickly when you notice the first signs of activity can prevent a minor problem from becoming a major infestation.
