The city utilizes targeted ground level spraying to help reduce the mosquito population in areas where a mosquito-borne virus is detected, as recommended by the Tarrant County Public Health Department. The spraying is done by licensed professionals using ultra-low volume pesticide that is EPA-approved as being safe for humans and the environment. (U.L.V. MOSQUITOMASTER™ 412 or ANVIL® 2 + 2 ULV). While the pesticide is approved by the EPA, residents who are concerned about exposure may take the following precautions:

  • Avoid being outside while spraying occurs, close windows and consider keeping pets inside.
  • If skin or clothes are exposed, wash them with soap and water.
  • Rinse homegrown fruits and vegetables with water as a general precautionary measure. 
  • Cover small ornamental fish ponds.

If you have questions about spraying or would like your address to be placed on the do not spray list, please contact Public Works at 817-427-6460.

While spraying in public rights of way can somewhat reduce the number of mosquitoes in a given area, the results are only temporary. Health officials concur that the reduction or elimination of mosquito breeding areas is the best technique for mosquito control.

To prevent the overuse of pesticides in our community, spraying is limited to areas where mosquito-borne virus is detected. Mosquito samples are collected weekly across the city and submitted to Tarrant County Public Health for testing. Weekly surveillance reports are available from Tarrant County Public Health.
