When the Southern California sun turns up the heat, pest activity turns up right along with it.
Long, hot summers are nothing new to San Dimas and Los Angeles County homeowners, but many are surprised by how insects thrive in the heat. Whether it’s ants taking over your kitchen, mosquitoes buzzing in your yard, or aggressive wasps building nests, warm temperatures fuel pest activity in a big way.
In this post, we’ll break down:
– How extreme heat impacts pest behavior
– Which insects are most active during Southern California summers
– What you can do to prevent an infestation
– Why Versa-Tech Pest Management is the top-rated pest control company in San Dimas & Surrounding
☀️ Why Summer Heat Increases Insect Activity
Insects are cold-blooded, so their internal temperature and metabolism are affected by the environment. In summer, their metabolism speeds up, which means:
– Faster breeding cycles
– Increased movement
– More aggressive feeding behavior
Fun Fact: Some species of ants can double their colony size during a single summer season—especially when they find easy access to food and water in your home!
When the ground becomes scorching hot, pests often look for cooler, shaded areas—like inside your home.
What Pests Are Most Active in Southern California Summers?
Here are the pests to watch out for during peak heat:
• Ants
Argentine and odorous house ants are especially active in hot weather. They invade in large numbers and are difficult to eliminate without professional help.
• Mosquitoes
Mosquitoes breed faster in warm weather, especially near standing water. Summer is prime mosquito season in SoCal.
• Wasps & Yellowjackets
These stinging insects become more territorial and aggressive in the heat. They often build nests in trees, rooflines, or underground.
• American Cockroaches
Roaches (also known as sewer roaches) are large, fast pests are drawn to warm, humid areas like drains, sewers, and basements.
• Spiders
Black widows and other common spiders come out in summer to feast on the increased insect population.
How to Protect Your Home from Insects During Heatwaves
Here are some simple but powerful pest prevention tips:
– Eliminate standing water (birdbaths, planters, buckets)
– Seal cracks and crevices around windows, pipes, and foundations
– Store food properly to avoid attracting ants and roaches
– Clean gutters and trim plants to eliminate spider and wasp habitats
– Schedule a professional inspection before pests get out of control
