Apply personal insect repellents that contain the active ingredients DEET or picaridin. Be sure to follow the instructions on the label and reapply as directed.
Wear pants, long-sleeve shirts, and socks to limit the amount of skin that is exposed to mosquitoes. Consider wearing clothing and gear treated with a personal repellent for an added layer of protection.

Use screens on windows and doors and repair holes in screens to help keep mosquitoes outside.
Eliminate areas of standing water in and around the home and be sure to dump collected water at least once a week. Some common areas where mosquitoes lay their eggs include old tires, buckets, bird baths, and trash bins.
