Mosquito Control

Fight the Bite!
While NO positive mosquito traps have been identified in Lancaster this year, there have been several positive confirmations in surrounding cities within Dallas County. “It is best to knock down the mosquito population as much as possible to help eliminate an increased risk of human exposure to West Nile virus,” explained Zachary Thompson, DCHHS director.
Residents should use the FOUR D's to reduce exposure to mosquitoes:
  • DEET All Day, Every Day: Whenever you’re outside, use insect repellents that contain DEET or other EPA approved repellents and follow instructions.
  • Dress: Wear long, loose, and light-colored clothing outside.
  • Drain: Drain or treat all standing water in and around your home or workplace.
  • Dusk & Dawn: Limit outdoor activities during dusk and dawn when mosquitoes are most active. 
Mosquito season in Dallas County is from April to November. Residents should be on a heightened alert during these months. West Nile Virus is spread by the bite of a mosquito. Mosquitoes become infected when they feed on the blood from infected birds. Infected mosquitoes can then transmit West Nile Virus to humans and animals. North Texas has recently experienced a massive amount of rainfall, which has resulted in standing water in pools, buckets, ponds and fountains. Standing water is the breeding area for mosquitoes.
Joint City/County Efforts
The City of Lancaster Public Works Department and Dallas County Health and Human Services highly recommend removing all standing water and utilizing Mosquito Dunks for all ponds, fountains and other water features. Mosquito Dunks are also known as Larvicides, which are used to kill immature mosquitoes before they become adults. In hopes to limit the overall mosquitoes in Lancaster, FREE Mosquito Dunks are available to Lancaster residents at 211 N. Henry Street and at 700 E. Main Street.
