1. Eliminate standing
water close to the dwelling. Mosquitoes can successfully breed in an old cottage cheese container left outside.
2. Any standing water you can't eliminate, put some carnivorous fish in there, preferably
native. Or BT dunks.

3. Encourage everything that eats mosquitoes, dragonflies, fish, birds, spiders,
bats, etc.
4. Wear long sleeves and a bug net when it gets bad.
5. DEET, last resort, but effective.
