How to Prevent Mosquitoes in Your Yard

The best way to prevent mosquitoes from causing trouble is to eliminate breeding sites. Experts recommend these steps:

• Dump standing water every week. Empty buckets, plant saucers, birdbaths, and clogged gutters; these are prime breeding grounds for mosquitoes.
• Use window and door screens to keep mosquitoes out.
• Maintain your yard by trimming plant matter where mosquitoes like to rest.
• Use EPA‑registered insecticides or larvicides when needed.

How to Prevent Mosquito Bites

Most of the mosquitoes on your property don’t travel far to bite you. There’s a chance they’re growing in your yard. The CDC and WHO recommend:

• Use EPA‑registered repellents that contain DEET, picaridin, IR3535, or oil of lemon eucalyptus.
• Wear long sleeves and pants outside, especially at dawn and dusk.
• Use air conditioning or screens to keep mosquitoes out of indoor spaces.

Follow these guidelines to keep your family safe from mosquito bites this year.
