Mosquitoes are more than a nuisance — they transmit West Nile virus, Zika, and other diseases, and they breed in as little as a bottle cap of standing water. This guide covers how to identify the breeding sites around your home, which treatments actually reduce populations, and how to protect yourself and your family from bites.
Start with the complete guide: Best Mosquito Killer for product recommendations, or read on for the full strategy.
Why Mosquitoes Breed in Your Yard
Female mosquitoes lay eggs in standing water — and they need very little of it. Clogged gutters, plant saucers, birdbaths, tarps, and even children’s toys can become breeding sites. The key to reducing mosquito populations is eliminating standing water, not just spraying adults.
Our guide to mosquito breeding standing water checklist covers the full inspection, and mosquito life cycle and standing water explains why removing water is the most effective control method.
How to Treat an Active Mosquito Problem
For active populations, larvicides (like Bti dunks) kill larvae in standing water you cannot drain. Adulticides — foggers or yard sprays — kill adults but have no residual effect, so they must be repeated. Misting systems offer continuous control but are expensive to install and maintain.
Our guide to best mosquito larvicides and dunks covers the water-treatment method, and best mosquito yard spray covers the adult-kill options. If you’re considering a misting system, mosquito misting systems: work, cost, drawbacks covers the honest pros and cons. For traps, best mosquito trap covers the CO2 and attractant options.
How to Protect Yourself Outdoors
Use an EPA-registered repellent containing DEET, picaridin, or oil of lemon eucalyptus. Wear long sleeves and pants at dawn and dusk when mosquitoes are most active. Install or repair window and door screens. For patios and porches, a combination of fans (mosquitoes are weak fliers) and targeted sprays works better than candles or ultrasonic devices.

When to Call a Professional
Call a professional for large properties with persistent breeding sites, or if you have a severe infestation that home treatments haven’t reduced. Professional mosquito control typically involves yard fogging plus larvicide application and costs $300–$500 per season.
Frequently Asked Questions
When do mosquitoes come out?
Most species are active at dawn and dusk. See when do mosquitoes come out.
How long do mosquitoes live?
Adults live 2–4 weeks, but the life cycle can complete in 7–10 days in warm weather. See how long do mosquitoes live.
Do mosquito bracelets work?
No — independent testing shows they provide little to no protection. See do mosquito bracelets work.
