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 samples were collected from testing areas near 2612 Round Up Trail and 1611 Lago Vista Drive.
In response to these findings, the Town has coordinated targeted mosquito control treatments in the affected areas. The goal of these operations is to reduce the adult mosquito population and limit the potential spread of mosquito-borne illness.
Mosquito spraying is scheduled for Monday, June 15, 2026, and Tuesday, June 16, 2026. Treatments will begin at 9:00 p.m. each night. The work will be conducted by a licensed mosquito control contractor using Aqua Perm-X UL 30-30. This is an EPA-registered product specifically designed for public health mosquito abatement programs. The product is applied as an ultra-low-volume mist and is commonly used throughout Texas and the United States for mosquito control.
Residents in the treatment areas are encouraged to take specific precautions during the spraying operations. Residents should remain indoors during active spraying when possible. Pets should be brought inside or kept away from the spray area. If windows and doors are open during treatment, they should be closed. Residents may also cover outdoor items such as pet food, water bowls, and children's toys if desired.
While spraying helps reduce adult mosquito populations, the Town emphasizes that eliminating mosquito breeding sites remains the most effective long-term defense against West Nile Virus. The Town encourages everyone to continue following the four Ds of mosquito prevention: use insect repellent containing DEET, picaridin, or oil of lemon eucalyptus; wear long sleeves and long pants; drain standing water from around homes and property; and limit outdoor activity during dusk and dawn.
The Town will continue monitoring mosquito activity throughout the community and will take additional measures as necessary to protect public health.
