Quick answer

What to know first

Mosquito management works best when standing water is removed before adults build up. Even small containers can produce mosquitoes quickly in warm weather.

Check first

  • Buckets, saucers, gutters, tarps, bird baths, tires, and low spots
  • Wiggling larvae at the water surface
  • Shaded vegetation, patios, and dawn or dusk bite activity

Avoid this

  • Only treating adult mosquitoes while breeding water remains
  • Forgetting small containers that refill after rain
  • Using repellents as a substitute for source reduction

Overview

Mosquito management is most effective when breeding sites are removed before adult populations build. Small containers, clogged gutters, saucers, tarps, and bird baths can produce mosquitoes quickly in warm weather.

Key signs to check

Adult mosquitoes active at dawn, dusk, or shaded areas
Wigglers or larvae in still water
Bites after time outdoors
Standing water in containers, gutters, drains, or low spots

What to do now

  1. 1Empty standing water at least once a week.
  2. 2Treat water that cannot be drained with labeled mosquito dunks.
  3. 3Use EPA-registered repellents when exposure is likely.
  4. 4Improve airflow and reduce dense resting vegetation near patios.

Prevention checklist

Clean gutters and correct drainage issues.
Store buckets, toys, and containers upside down.
Change bird bath and pet water frequently.
Use screens on windows and doors.

When to call a professional

Call a professional when mosquitoes remain heavy after water removal or when a yard has persistent drainage and vegetation issues.
