Pest Seasons in Los Angeles
Los Angeles’ Mediterranean climate — with hot, dry summers and mild, wet winters — creates a unique environment where pests thrive year-round. Unlike colder regions where insects die off in winter, LA’s temperature rarely drops low enough to significantly reduce pest populations. Instead, different pests peak at different times of the year, moving between outdoor breeding grounds and indoor shelters as conditions change.
Understanding seasonal pest patterns can help you stay ahead of infestations. Spring brings swarming termites as colonies expand after winter rains. Summer heat drives ants and cockroaches indoors in search of food and water. Fall sees increased rodent activity as rats and mice seek warm nesting sites. Even winter brings its own challenges, with rodents and spiders becoming more noticeable inside homes.
