City Debuts New Mosquito Control Measures

Post Date:05/11/2018 5:00 PM

The Richardson Health Department will soon deploy several new bait devices that allow mosquitoes to transport mosquito larvicide from the device to other breeding locations. The innovative device uses the mosquito’s own biology to help control the population by spreading larvicide to multiple breeding sites. The newly designed technology was developed with funding from the Bill and Melinda Gates Foundation for use in control of mosquito-borne diseases around the world. Richardson is the first city in North Texas to use the devices, part of the City’s ongoing, comprehensive efforts to control mosquitoes and mosquito-borne disease.

From April-October, traps are set out across the City and tested weekly, with spraying conducted as needed whenever West Nile virus is found in trapped mosquitoes. Residents are encouraged to follow the "Four D’s" of protection:

  • Drain standing water
  • Avoid being out at dusk/dawn
  • Dress in long sleeves and pants
  • Apply insect repellent containing DEET or other effective repellents all day every day
