California's varied climate means ants are a persistent problem across the state. In Southern California, from Anaheim to Riverside and Moreno Valley, the warm weather allows ants to be active all year long. They are constantly looking for food and water. Even in cooler coastal areas like Santa Rosa, ants can find ways to get inside homes. Many homes in California, whether single-family houses or apartment buildings, offer numerous entry points for ants. The housing stock is diverse, but common issues include cracks in foundations and gaps around windows and doors. Dry periods can also drive ants indoors seeking moisture.
