Repair any holes in screens and seal off insect entry points, particularly around windows, doors, and foundation cracks. (Likewise, don't leave food out; unattended morsels are irresistible to flies, yellow jackets, and wasps.)

Airflow makes a big difference, whether it's a natural breeze or one created by a ceiling or portable fan. Mosquitoes are lousy pilots in turbulence.

Regularly mow your yard to control grass height. Keep weeds pulled, and remove any fallen fruit from trees.

Nip mosquitoes in the bud by reducing standing water around your house. This includes emptying any pails and containers, keeping gutters free of debris, and examining planters and tree holes. Use biological mosquito control dunks in water features such as birdbaths and ponds. Dunks will not make the water harmful to fish, birds, pets, or wildlife.
