The Township recommends several personal protective measures, including:

  • Wear repellent when outdoors when West Nile virus is known to be circulating. There are special considerations for children – see this Parents Guide to Repellent. Repellent is especially important if someone: 
    • Is outside in the early morning or evening hours when mosquitoes are most active
    • Is over age 50
    • Has underlying health conditions  
  • The mosquitoes that carry WNV are more active at dusk, dark, and the early dawn hours. Consider changing your routine if you are normally outdoors during these times, or create a barrier by covering up skin with long sleeves and pants. 
  • “Drain after Rain” to deny mosquitoes a place to lay their eggs and reproduce. Empty out water that accumulates in toys, tires, trash cans, buckets, clogged rain gutters, and plant pots.  
  • Treat water you do keep – in bird baths, rain barrels, and ponds – with non-toxic Mosquito Dunks®. Cheap, easy, and safe for pets and wildlife, you can find them at your local hardware store.

Backyard and Patio Measures

  • Use an oscillating fan while outdoors (overhead fans are not effective at keeping mosquitoes away)
  • Keep french drains and meter boxes clean and free of standing water
  • Consider using rain barrels and creating a rain garden in your yard
  • Use liquid garlic concentrate diluted with water and apply with a pump sprayer to plants and structures around the perimeter of your yard
  • Water landscape deeply and infrequently – an inch a week is enough

The mosquito treatment map and schedule is available for the following local areas:

  • South Montgomery County map and information is available here
  • Harris County map and information is available here
