Why Are Mosquitoes Worse After Storms in St. Louis?

Summer storms in St. Louis can often be dangerous and damaging – but what about mosquitoes after the storm?

When summer storms roll through St. Louis, we often experience swampy lawns, flooded gutters, and cooler evenings. What you might not have expected is a huge influx of mosquitoes in your yard. If you’ve noticed the uptick, you’re not alone. Why are mosquitoes suddenly everywhere after storms?

Storm Residuals Create the Mosquito Breeding Grounds

Mosquitoes love warm and wet environments left by heavy rainfall. July and August are often overrun with mosquitoes due to heavy rainfall that leaves behind standing water, clogged downspouts, and lawn overgrowth. It takes a seriously minuscule amount of water for mosquitoes to lay their eggs and for larvae to grow. We’re talking about a bottle cap of water yielding hundreds of larvae – so imagine what puddles and clogged storm drains can produce!

Check on These Storm-Related Mosquito Breeding Sites

• Clogged gutters and downspouts
• Birdbaths and plant saucers
• Tarps and pool covers with standing water
• Low-lying areas of your lawn that collect runoff
• Trash receptacle lids and toys left outdoors
• City storm drains by the street

Take Action Before the Swarm

Post-storm, it’s critical to act fast to help allay drastically increased mosquito populations around your home or business.

Here are a few things you can do:

• Dump and drain anything that holds water within 48 hours
• Inspect your property for hidden breeding sites like plant trays or old tires
• Keep gutters clean to avoid water pooling along your roofline
• Trim shrubs and grass to reduce mosquito hiding spots
