Mosquito control activities in Richardson are conducted year-round but are increased from April through October when the insects are most active.

Crews set up Mosquito surveillance traps in 12 areas of the City on a weekly basis with mosquitoes collected and later sent to a lab for West Nile Virus testing.

If a sample comes back positive, the management area surrounding the sample’s trap is sprayed.

“The Mosquitoes that carry West Nile Virus are most active between Dusk and Dawn. There are daytime biters and they are the ones that normally do not carry the West Nile Virus,” said Janet Tucker, senior environmental health specialist.

Residents can follow the Four D’s to protect themselves: DRAIN standing water around the home, Use insect repellent containing DEET, Avoid being outdoors at DUSK and DAWN, and DRESS to protect yourself with long sleeves and pants.
