The City of Cedar Hill conducts mosquito control activities year-round but increases those efforts from April through October, the most active mosquito season in North Texas. The City coordinates with Dallas County Health and Human Services (DCHHS) to conduct surveillance, trapping and testing of the mosquito population for diseases including West Nile Virus (WNV). 

There are currently five Mosquito Management Areas in Cedar Hill where mosquitoes are trapped weekly and then taken to a Dallas County lab for testing. If a mosquito trap yields a positive result for West Nile Virus, Dallas County Mosquito Control will schedule an overnight spraying event in the affected management area beginning Sunday night.
