California pest control: common pests, seasons & local options
From the Golden Gate to the deserts of the south, California's microclimates host nearly every pest in the book. Los Angeles, San Diego, San Jose, San Francisco, and Sacramento homeowners battle year-round Argentine ants, drywood and subterranean termites, roof rats, and urban bed bugs.
Most common pests in California
The four pest problems California homeowners ask about most — and what drives them locally.
Termites
Both subterranean and drywood termites attack California homes — swarms arrive with fall rains and warm spring days.
Ants
Argentine ants form massive supercolonies across California, trailing indoors whenever weather shifts.
Rodents
Roof rats and Norway rats pressure California cities from Los Angeles to Sacramento.
Bed Bugs
California's dense metros and heavy travel make bed bugs a persistent urban challenge.
Pest seasons in California
California's mild climate means no true off-season: ants invade with both winter rains and summer heat, termite swarms follow the first fall storms, and rodents press indoors in winter. Coastal fog and inland heat each drive their own pest rhythms.
