- DEET - All Day, Every Day: Whenever outside, use FDA approved insect repellants that contain DEET, picaridin or lemon-eucalyptus oil.
- DRESS: Wear long, loose fitting, light-colored clothing when going outdoors.
- DRAIN: All areas of standing water in or around your home where mosquitos can lay their eggs.
- DAWN, DAY & DUSK: Limit your time outside as mosquitos will bite day and night.
