8/28/2020 - West Nile Virus Update

West Nile Virus Update

Sep 15, 2020 Update: The County performed an additional mosquito test on Sep 11 from traps placed in Brushy Creek MUD and all results came back negative for West Nile virus.   

A sampling of mosquitoes in Leander, Georgetown, and Austin have tested positive for West Nile Virus and two traps located in Brushy Creek MUD had a positive result. One infected mosquito was near the Great Oaks and Cornerwood Dr. area and the other was near Cat Hollow Park. 

* Please dump out any outdoor containers with standing water.

What Can You Do?  The Four Ds: 

Dusk & Dawn: Be especially cautious during this time of the day. The species of mosquitoes that spread West Nile Virus are most active between dusk and dawn.
Dress: Wear pants and long sleeves when you are outside. 
DEET: Apply insect repellent that contains DEET.  Spray both exposed skin and clothing with repellent. 
Drain: Get rid of standing water in your yard and neighborhood. Old tires, flowerpots, clogged rain gutters, birdbaths and wading pools can be breeding sites for mosquitoes.

Fight the Bite Mosquito Management

Recent Williamson County News Releases:

Brushy Creek MUD and Williamson County Parks Department staff will continue mosquito control efforts with draining or treating standing water with larvicide. For more information, go to the WCCHD website at www.wcchd.org or visit the Texas Department of State Health Services West Nile website at www.txwestnile.org.

Ways to eliminate mosquito breeding sites:

- Reduce standing water around your home and neighborhood (including plant saucers, toys, buckets, and clogged gutters)
- Replace water at least once a week in pet dishes and birdbaths
- Repair leaky faucets and pipes
- Keep window and door screens in good repair
- Carefully screen rainwater harvesting cisterns to exclude mosquitoes
- Use “mosquito dunks” (Bacillus thuringiensis israeliensis) to reduce mosquitoes in rain barrels and permanent bodies of water. These products slowly release a biological larvicide that kills the pest
