Central Valley is no stranger to the delights of summer. We enjoy long summer days and fun events that bring our community together. But along with the joys of summer come some less pleasant guests: pests.

In this blog, we’ll dive into the common pests in California during the summer, helping you understand what to watch out for and how to protect your home. Let’s explore the pesky side of summer and learn how to keep these unwelcome visitors at bay.


Ants are probably the most notorious summer bugs in California. These tiny invaders are constantly on the lookout for food, and our summer picnics provide the perfect opportunity. While there are many species of ants, the ones you’ll most likely encounter are Argentine ants and thief ants. These pests aren’t just a nuisance; they can contaminate food and cause significant damage to your home.

How to Deal With Ants:

  • Food can attract ants, so keep it sealed and stored in airtight containers.
  • Clean up spills and crumbs immediately.
  • Use natural repellents like vinegar and lemon juice around entry points.


Mosquitoes are synonymous with summer and can quickly ruin an evening outdoors. These pests are not just annoying; they can carry harmful diseases like West Nile virus and Zika virus. Standing water is their breeding ground, so be sure to eliminate any stagnant water around your home.

Preventing Mosquito Infestations:

  • Empty and clean birdbaths, pet water dishes, and other containers that collect water.
  • Use mosquito repellent when spending time outdoors.
  • Install screens on windows and doors to keep mosquitoes out of your house.

Stinging Insects: Wasps, Bees, and Yellow Jackets

Stinging insects like wasps, honey bees, and yellow jackets become very active during the summer months. These common pests in California during the summer are attracted to sweet foods and drinks, making outdoor gatherings a risky affair. Wasps can sting multiple times, which can be dangerous, especially for those with allergies.

Tips for Staying Safe From Stinging Insects:

  • Keep food and drinks covered when outdoors.
  • Avoid wearing brightly colored clothing and strong fragrances.
  • Hire a professional wasp nest exterminator if you spot a nest near your home.


Flea infestations can be particularly troublesome during the summer. These tiny pests not only irritate pets but can also bite humans, leading to itchy welts. Fleas are known to transmit harmful diseases like typhus and plague.

Managing a Flea Infestation:

  • Regularly groom and bathe your pets.
  • Vacuum your home frequently to remove flea eggs and larvae.
  • Use flea treatments and consult your vet for the best options.


Termites, especially subterranean and drywood termites, are a year-round threat but can be particularly active in the summer. These pests cause extensive damage to wooden structures, leading to costly repairs.

Protecting Your Home From Drywood and Subterranean Termites:

  • Schedule regular termite inspections.
  • Reduce moisture issues around your home’s foundation.
  • Keep firewood and debris away from your house.


Spiders are among the most common California insects in the summer. While most spiders are harmless and even beneficial by controlling other insect populations, their webs can be a nuisance. Some species, like the black widow, can be dangerous to humans.

Managing Spiders:

  • Declutter: Reduce clutter in your home where spiders can hide.
  • Vacuum Regularly: Remove webs and potential egg sacs by vacuuming frequently.
  • Seal Cracks: Prevent spiders from entering by sealing cracks and gaps.


Maybe it goes without saying, but flies are also some of the most common pests in California during the summer. They’re attracted to food and waste, making outdoor gatherings and kitchens their favorite spots. Flies can spread bacteria and cause food contamination.

Keeping Flies Away:

  • Keep food covered and dispose of waste properly.
  • Use fly screens on windows and doors.
  • Set up fly traps around your home.

Bed Bugs

Bed bugs are notorious for their ability to hide and breed rapidly. These pests are typically more active during the warm weather and can turn a peaceful night’s sleep into a nightmare.

Controlling Bed Bugs:

  • Regularly inspect your bedding and furniture.
  • Use protective mattress covers.
  • Consult a pest control professional for effective treatments.


Cockroaches thrive in warm, humid environments and are known for their resilience. These pests can spread diseases and trigger allergies and asthma attacks.

Cockroach Prevention:

  • Keep your home clean and dry.
  • Fix any leaks to reduce moisture.
  • Use bait traps and call a pest control service if the infestation persists.

The Role of Weather in Pest Activity

Warm weather and increased moisture during the summer months create ideal conditions for many pests. Insects like mosquitoes and termites prosper in these environments, leading to higher populations and more frequent infestations.
