California Common Pests

The California climate is one of many things that attract people to move here, but bugs like it too! If you live in California, chances are you’ve had your fair share of encounters with household pests. From bugs in the kitchen to critters in the attic, these unwelcome guests can make life pretty uncomfortable. But what bugs are most common in California homes? 

Bed Bugs

If you’re like most people, the thought of bed bugs makes your skin crawl. And for good reason—these tiny pests can wreak havoc on your home and your health. Bed bugs are the most active in California in warmer months, making this “bed bug season.” 

Some of the most common signs of bed bugs are:

  • Red spots on your bedding
  • A mysterious, musty odor coming from your bed
  • Small, unexplainable bites
  • Shed skins & egg shells around your house


Earwigs are all over California! They get their name from an old wives’ tale that says they like to crawl into people’s ears and lay their eggs there. (They don’t actually do this, by the way). Despite their creepy appearance, earwigs don’t bite and aren’t dangerous to humans. However, they can be a nuisance if they invade your home in large numbers. And fun fact, they are closely related to cockroaches! 


If you live in California, chances are you’ve seen a silverfish or two. Silverfish are small, wingless insects that get their name from their silvery-gray color. They are harmless to humans and don’t carry diseases, but they can be a nuisance as they’re known for eating paper and clothing, which can damage your belongings. 

Silverfish are attracted to damp, dark places and can often be found in:

  • Basements
  • Kitchens 
  • Bathrooms
  • Attics


Spiders are another extremely common pest all over the world. While many detest spiders, they are actually very important for our ecosystems! Even the “dangerous” ones are not likely to cause harm unless they feel threatened. Even though they are found globally, the most common spiders in California you might find in your home are:

  • Wolf Spiders
  • Brown Recluses
  • Black Widows
  • American Household Spiders

Carpet Beetles

Carpet beetles are one of the most common household pests in California. They’re small, round, and black, and they love to feast on carpeting and fabrics. If you have carpet beetles in your home, you’ll probably notice them first in areas where there’s a lot of fabric, like on your furniture or in your closet. These pests are especially difficult to get rid of once they’ve infested an area. If you think you might have carpet beetles, it’s important to call a pest control professional as soon as possible.
