Quick Answer
Signs of a ground squirrel infestation include visible burrows, mounds of dirt, and droppings in clusters. They often occur in large numbers near structures, gardens, and food sources. Infestations can cause significant damage to crops and landscaping.
Identifying Ground Squirrel Habits
Ground squirrels in California are primarily crepuscular, meaning they’re most active during twilight hours. They often inhabit areas with loose soil, such as vacant lots, construction sites, and golf courses. Squirrels tend to dig burrows near food sources, like gardens and bird feeders, and will often reuse existing burrows.
Common Signs of Infestation
When looking for signs of ground squirrel infestation, inspect areas for visible burrows, typically 2-3 inches in diameter. These burrows often have a small entrance and two larger exits. Ground squirrels also create mounds of dirt when digging, which can appear as small hills or mounds of loose soil. Keep an eye out for droppings in clusters near burrows, which can be a sign of multiple squirrels inhabiting the area. In California, it’s common to see ground squirrels in areas with abundant food sources, such as bird feeders, pet food, and compost piles.
Prevention and Control Measures
To prevent ground squirrel infestations, keep gardens and landscapes clean, removing any debris or food sources that may attract them. Use squirrel-proof bird feeders and store pet food in secure containers. Consider using repellents or deterrents, such as predator urine or hot pepper sprays, to discourage squirrels from entering the area. In severe cases, consider consulting a wildlife control professional to humanely remove the infestation. In California, ground squirrels can be active year-round, making regular inspections and maintenance crucial to preventing infestations.
