The Town of Little Elm has confirmed that two mosquito samples collected through its ongoing surveillance program tested positive for West Nile Virus. The positive results came from testing sites located near 2612 Round Up Trail and 1611 Lago Vista Drive.
In response to the findings, the town has arranged for targeted mosquito control treatments in the affected zones. The goal of these operations is to lower the adult mosquito population and reduce the potential for further spread of mosquito-borne illness. Little Elm is about 12 miles east of Denton.
Spraying is scheduled to take place on Monday, June 15, 2026, and Tuesday, June 16, 2026. The work will begin at 9:00 p.m. each night. A licensed mosquito control contractor will perform the application using Aqua Perm-X UL 30-30. This product is registered with the Environmental Protection Agency and is designed specifically for public health mosquito abatement programs. It is applied as an ultra-low-volume mist and is commonly used across Texas and the United States for similar control efforts.
Residents living in the treatment areas are advised to take specific precautions during the spraying operations. Officials recommend staying indoors while spraying is active whenever possible. Pets should be brought inside or kept away from the spray zone. Homeowners are also asked to close any open windows and doors during the treatment. Covering outdoor items such as pet food, water bowls, and children's toys is also suggested.
While the spraying helps reduce adult mosquito numbers, the town emphasizes that eliminating breeding sites is the most effective long-term defense against West Nile Virus. Residents are encouraged to follow the "4 Ds" of mosquito prevention. This includes using insect repellent containing DEET, picaridin, or oil of lemon eucalyptus. Wearing long sleeves and long pants is also recommended, particularly during peak mosquito activity times.
Removing standing water from around homes and properties is another key step. This includes emptying flower pots, bird baths, gutters, buckets, and other containers where mosquitoes might breed. Limiting outdoor activity during dusk and dawn is also advised, as mosquitoes are most active during these periods.
