Why Southern California Doesn't Have One Clean Pest Season

Unlike East Coast states that experience harsh winters, Southern California’s weather is relatively mild throughout the year, something most people love about living here. However, this also means that there are no intense cold spells to sharply reduce seasonal pest activity like mosquitoes come fall and winter. Therefore, their activity lasts much longer (sometimes even all year).
After all, without harsh winters, insects and rodents can resume activity quickly between seasons, while irrigation and indoor shelter create favorable microclimates in which they can survive. But still, ants, mosquitoes, spiders, fleas, rodents, and other pests respond differently to rain, heat, food, and habitat, which means they’ll still peak at different times throughout the year.
Mild Weather Extends Activity, but Different Pests Still Peak at Different Times
Even with longer activity periods, pests will still peak at certain times here in Anaheim, CA. During warmer stretches, insects’ foraging periods extend, extending their activity and potentially creating more pest pressure around homes and yards. But once that heat intensifies, other pests like rodents will move indoors.
Rodents will seek refuge in structures wherever they can access food, water, and shelter. During especially rainy, moisture-heavy periods, this is especially true, as they can stay away from excess water, while other pests like mosquitoes can boom because they need water to breed.
What Anaheim Homeowners Should Check All Year
Keeping your pests away from your family and home in Anaheim means staying vigilant year-round, not just during peak seasons. Here are a few year-round basics we recommend implementing on a regular basis to help keep pests away from your house:
- Check for standing water in gutters and other objects in your yard.
- Manage irrigation and any leakage around your home.
- Store food properly and keep garbage bins sealed tight and stored away from your home’s siding.
- Check window and door screens for holes and inspect your seals for any gaps or wear and tear.
- Don’t let vegetation directly touch your house.
- Tidy up clutter, which can act as harborage for pests like rodents.
- Inspect your home regularly, and recheck after rain, heat waves, landscaping, or construction.
