The Health Department had a trap located in the Breckinridge Park area return mosquitoes this week that tested positive for carrying West Nile virus, the City’s first positive test result of 2021. The Department conducted ground spraying in that area (see map) Tuesday and Wednesday. No human cases of West Nile virus in Richardson have been reported.

It is later than average for Richardson to record its first positive mosquito result, which is encouraging considering the amount of area rainfall the city has experienced this spring and summer. The Health Department has been advising residents to follow The Four D’s of Protection against mosquito-borne illness to reduce mosquito populations and protect against bites:

  • Drain standing water around the home
  • Avoid being outdoors at dusk/dawn
  • Dress to protect yourself with long sleeves and pants
  • Apply insect repellent containing DEET or other effective repellants
