Protect Yourself from West Nile
- Use EPA-approved mosquito repellent containing DEET and follow the label directions.
- If you are outdoors between dusk and dawn when mosquitoes are most active, be sure to wear long pants, a long-sleeved shirt, shoes, and socks.
- Wear light-colored clothing, which is less attractive to mosquitoes.
- Install or repair screens on windows and doors to keep mosquitoes out of your home.
- Make sure all roof gutters are clean and drained properly.
- Eliminate standing water in your yard as well as from flower pots, buckets, and barrels. Change the water in pet dishes and replace the water in bird baths weekly. Drill holes in tire swings so water drains out. Keep children’s wading pools empty and on their sides when they aren’t being used.
For more information, call 937-225-4362.
