DALLAS (October 5, 2022) – The Dallas County Health and Human Services (DCHHS) laboratory has confirmed mosquito samples that have tested positive for West Nile Virus. The mosquito samples were collected from the 75137 zip code in Duncanville, and 75115 in DeSoto, TX. In conjunction with the Dallas County municipalities, mosquito abatement teams are responding by treating impacted areas. DCHHS has scheduled ground spraying in the below area(s), weather permitting.

“Mosquito bites can cause West Nile Virus Infection, and we need to remain vigilant to prevent mosquito bites. It’s important to remember the four Ds: DEET, Dress, Drain, and Dusk to Dawn”, said Dr. Philip Huang, Director of DCHHS.

The City of Duncanville, at the recommendation and in cooperation with Dallas County Health and Human Services (DCHHS), will be conducting ground spraying against mosquitoes on Thursday, October 6 and Friday, October 7, between the hours of 9:00 PM and 5:00 AM, weather permitting.

The spraying is being conducted in response to the detection of West Nile Virus in a mosquito trap within the 75137 zip code. If the weather prohibits spraying on Thursday night, spraying will be conducted on Friday and Saturday nights. Spraying will be performed in the targeted area within the City of Duncanville. Residents living within the spray zone are encouraged to remain indoors and bring their pets inside during spraying.

City staff will continue to monitor areas where mosquito breeding is most likely to occur.

To prevent the spread of mosquitoes, residents should remove all areas of standing water.

Residents should also report all pools that are not well maintained and abandoned homes
where mosquitoes are likely to breed to either City of Duncanville Health Services or
Neighborhood Services by calling (972) 780-5040.

Everyone should continue to protect themselves against the West Nile Virus by using insect
repellent containing DEET. Citizens are also encouraged to remain indoors during dawn and
dusk when mosquitoes are most active.

DEET: Whenever outside, use insect repellents that have the active ingredient DEET or other EPA-registered repellents, and always follow label instructions.

DRESS: Wear long, loose, and light-colored clothing outside.

DRAIN: Drain or treat all standing water in and around your home or workplace where mosquitoes could lay eggs.

DUSK to DAWN: Limit your time outdoors from dusk to dawn when mosquitoes are most active.

DCHHS encourages residents in affected areas to be a part of the solution by eliminating insect breeding areas and larvae before they develop into an adult, flying mosquitoes. Standing water can be treated with EPA-approved larvicides that are available for retail purchase.

 

Larvicides are products used to kill immature mosquitoes before they become adults. Larvicides are applied directly to water sources that hold mosquito eggs, larvae, or pupae. When used consistently, larvicides can help reduce the overall mosquito burden by limiting the number of mosquitoes that are produced, according to the Centers for Disease Control and Prevention (CDC).
