Why Mosquitoes Get Worse After Rain & What to Do

Posted on November 3, 2025

You’d think a heavy storm would wash mosquitoes away, but it actually does the opposite. Mosquitoes after rain are usually worse because wet yards create more breeding spots. If you live in a humid or storm-prone area, you’ve probably noticed bites spike just a day or two after a downpour.

How Rain Creates Mosquito Breeding Grounds

Mosquitoes need water to reproduce, and rain gives them plenty. After storms you’ll often find:

  • Puddles in low spots of the yard.
  • Water pooling in toys, planters, and buckets.
  • Gutters clogged with leaves that trap water.
  • Damp soil that doesn’t dry out for days.

Signs of Mosquito Activity After a Storm

  • More bites within 24–48 hours of rain.
  • Groups of mosquitoes hanging near shaded, damp areas.
  • Buzzing near standing water, gutters, or planters.

DIY Steps to Reduce Standing Water in Your Yard

  • Dump water from buckets, pots, and toys.
  • Clear gutters and drains.
  • Rake up leaves and debris that trap moisture.
  • Refresh birdbaths and pet bowls daily.
  • Fill low areas in the yard where puddles form.

Professional Mosquito Treatment After Rainstorms

DIY helps, but professional treatment locks it in. After storms, mosquito control services can:

  • Treat adult mosquitoes on contact.
  • Target wet areas where they breed.
  • Build a barrier around your property to reduce activity.

That way, you’re not dealing with itchy bites every time it rains. Learn more about our Mosquito Control services, check our blog on preventing stagnant water breeding, or connect with your local staff in storm-prone areas like Tampa and Atlanta.
