What is the best way to keep mosquitoes away?
Reduce breeding sites
Mosquitoes lay eggs in standing water. Dump out any containers that hold water, like buckets, plant saucers, old tires, and clogged gutters. Change water in bird baths and pet bowls at least weekly. Fix leaky outdoor faucets and drain areas where water pools.
For water you can't drain, like rain barrels, use mosquito dunks containing Bti, a bacteria that kills larvae but is safe for other wildlife. This is a long-term strategy that reduces the population around your home.
Protect yourself
Use an EPA-registered repellent on exposed skin. DEET (20–30%) and picaridin (20%) are the most effective and last several hours. Oil of lemon eucalyptus is a plant-based option but may not last as long. Apply sunscreen first, then repellent. For clothing, permethrin-treated gear works well but should not be applied to skin.
Wear long sleeves and pants when possible, especially at dawn and dusk when mosquitoes are most active. Use screens on windows and doors, and repair any tears. A box fan on a porch can help, as mosquitoes are weak fliers.
- EPA-registered repellent with DEET or picaridin
- Permethrin spray for clothing (not skin)
- Window and door screens in good repair
- Mosquito dunks for standing water
- Box fan for patios
Yard treatments and traps
Professional yard treatments can reduce adult mosquitoes but are temporary. DIY foggers and sprays kill on contact but don't last long and can harm beneficial insects. Mosquito traps that use carbon dioxide or attractants can help but are not a complete solution.
If you have a severe problem, contact your local mosquito control district; many offer free or low-cost services. Also, check with your neighbors to eliminate shared breeding sites.
Common mistakes
- Relying only on citronella candles or ultrasonic devices, which have little to no proven effect.
- Forgetting to reapply repellent after swimming or sweating.
- Leaving standing water in hidden spots like clogged gutters or under potted plants.
