Riverside's warm, semi-arid climate and abundant landscaping make it an ideal habitat for ground squirrels. These burrowing rodents thrive in the region's residential neighborhoods, agricultural areas, and open spaces. The city's year-round growing season means food sources are available throughout the year—from ornamental plants and vegetable gardens to fallen fruit and seeds. Ground squirrels are particularly active during spring and early summer when they're breeding and raising young, but activity can persist through fall as they prepare for winter.
The expansion of suburban development in Riverside has brought human habitats closer to natural ground squirrel territories, increasing conflicts. Property owners often find squirrels burrowing under patios, in yard foundations, and near irrigation systems. Unlike tree squirrels, ground squirrels create extensive tunnel networks that can damage landscaping, undermine structures, and create safety hazards. Identifying ground squirrel activity early is crucial for preventing costly property damage and keeping these persistent pests under control.
Ground squirrels in Southern California are typically brown to gray with striped markings and are smaller than tree squirrels. Look for telltale signs of their presence: multiple small holes (about 1-2 inches in diameter) scattered across your yard, mounds of dirt around burrow entrances, and visible damage to plants and irrigation lines. You may also notice chewed vegetation, gnawed wood on structures, or the distinctive chatter and squeaking sounds they make when alarmed.
If left unchecked, ground squirrel colonies can expand rapidly. A single female can produce multiple litters annually, leading to widespread burrow systems that weaken soil integrity and damage underground utilities. In Riverside's residential areas, this can result in expensive repairs to sprinkler systems, foundation settling, and landscape restoration.
Controlling ground squirrels requires a multi-faceted approach. Exclusion is the first step—seal entry points to structures and remove debris piles where squirrels hide. Reduce food sources by installing secure trash containers, removing fallen fruit promptly, and using squirrel-resistant bird feeders. Hardware cloth barriers around gardens and raised beds can protect vegetable patches.
Trapping and removal are often necessary for established infestations. Live traps, snap traps, and other lethal control methods may be appropriate depending on infestation severity and local regulations. Fumigation of active burrow systems can also be effective for larger colonies. However, these methods require knowledge of squirrel behavior and proper technique to be successful.
