Mosquito Control and Prevention

Through its Integrated Mosquito Management program which includes public education, mosquito trapping and testing, reduction of standing water and mosquito abatement, the Environmental Health Division implements mosquito control activities year-round, depending on the weather. These activities include identifying locations with stagnant water and treating with larvicides as needed. The Environmental Health Division has also initiated code enforcement cases for stagnant water sources and launched ongoing education efforts. Staff responds to calls from residents as well as proactively inspecting and monitoring approximately 50 areas known for holding stagnant water.

Mosquitoes can transmit viruses such as West NileChikungunyaDengue and Zika

Increased rain escalates the number of nuisance mosquitoes, known as "flood mosquitoes." This species does not typically carry the West Nile Virus. Mosquito traps are placed around the community to monitor the mosquito population. Weekly tests for West Nile Virus begin May 1. Staff will stay in contact with Collin County health officials to monitor regional conditions, adjusting response activities if conditions warrant.

To report areas of stagnant water, or for additional inquiries, please email Environmental Services or call 214.509.4160.

The most effective method of controlling mosquitoes is to eliminate any habitat in which they would thrive or be attracted to. While the city continues to treat limited common areas, the greatest preventive impact comes from measures taken by each property owner to control mosquitoes around their homes.


The most effective way to avoid any mosquito-borne illness is to take the following simple precautions around the home. Follow the "Five D's":
  1. Drain standing water in your backyard and neighborhood; old tires, flowerpots and clogged rain gutters are mosquito-breeding sites. Change out pet water daily and keep swimming pools treated.
  2. DEET - Apply insect repellent that contains DEET (N, N-diethyl-m-toluamide). Be sure to read label instructions. Spray clothing with repellent as well as exposed skin.
  3. Dress in light colored long sleeves and long pants when you are outside.
  4. Dusk and Dawn is when mosquitoes are most active. Stay indoors or minimize outdoor activities.
  5. Doors and windows should remain closed and screens kept in good repair to prevent mosquitoes from entering your home.
