​The Environmental Health Department received notification that confirmed the presence of West Nile Virus (WNV) in a mosquito trap located in the 100 block of Blackburn Dr. DCHHS will conduct targeted ground spraying on Route 6,  on Tuesday, October 4th and Wednesday, October 5th between the hours of 9:00 p.m. and 5:00 a.m.  Should weather conditions not be conducive for spraying, trucks will spray the next available evenings.ZONE


Spraying for Mosquitoes

As a precaution, when spraying takes place in your neighborhood residents are recommended to stay indoors. Spraying will be conducted between the hours of 9 pm and 5 am.

​​​​​​​​​About Mosquito Trapping

Mosquito trapping begins in the spring, and continues until mosquito activity decreases, typically early fall.  The trapped mosquitoes are sent to a laboratory where they are tested for the presence of West Nile Virus.  Spraying activity will begin when notification is received that there is a positive mosquito sample of West Nile Virus.

How To Personally Protect Yourself Against WNV

Take every precaution to avoid being bitten by mosquitoes if at all possible.
Remember the 4 D’s: Defend, Dress, Dusk & Dawn, and Drain.
  • Defend yourself by applying insect repellant that contains DEET, Picaridin, Oil of Lemon Eucalyptus* or PMD. Use repellant all day, every day.
  • Dress in long sleeves and pants.
  • Stay indoors at dusk and d​awn.
  • Drain all stagnant water in your yard.
  • Additionally, you should p​rotect your home by using screens to keep mosquitoes outside. Use the air conditioning when possible.
Texas climate is always unpredictable and temperatures vary throughout the seasons.  As a result, mosquito season in Texas is year-round.  The Environmental Health Department's goal is to begin reducing mosquito populations as early in the season as possible. By eliminating containers, cleaning rain gutters, and maintaining swimming and ornamental pools you can stop the mosquito life cycle in its tracks.
