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 Persona​lly ​Protect Yourself Against Mosquito Borne Illnesses​

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.
