Dallas Schedules West Nile Virus Spraying in District 10 for June 22-23

The City of Dallas has scheduled mosquito control spraying in District 10 following positive West Nile virus tests from local mosquito samples. The targeted ground spraying will take place overnight from Monday, June 22 through Tuesday, June 23, as city health officials work to reduce the risk of virus transmission in the Lake Highlands area.

This latest spraying announcement comes amid an active West Nile season across North Texas, with multiple Dallas neighborhoods seeing increased vector control activity throughout June. The city's decision to target District 10 specifically follows surveillance data showing infected mosquito populations in the area.

What Residents Need to Know

The spraying operations will occur between 9 p.m. and 5 a.m. on both nights, weather permitting. City officials emphasize that this targeted approach focuses on areas where surveillance traps have confirmed the presence of West Nile virus in mosquito populations.

While the pesticide used is EPA-approved and applied at levels considered safe for humans and pets, residents in the spraying zone should take standard precautions:

• Stay indoors during spraying hours when possible
• Close windows and doors to minimize exposure
• Bring pets inside during treatment periods
• Rinse outdoor toys and furniture with water before use if left outside during spraying
• Cover fish ponds to protect aquatic life

West Nile Season Intensifies Across Metroplex

Dallas County health officials have been tracking increased West Nile activity throughout the region this summer. The virus, transmitted primarily through infected Culex mosquitoes, typically peaks in Texas between June and October, with the highest transmission rates occurring in August and September.

District 10 encompasses the Lake Highlands neighborhood, a densely populated residential area where the combination of mature trees, standing water from recent rains, and warm temperatures has created favorable conditions for mosquito breeding.

"The city's proactive approach to targeted spraying helps reduce the infected mosquito population quickly," said a spokesperson for Dallas County Health and Human Services. "But individual protection remains crucial throughout the season."

Protecting Yourself and Your Family

Beyond municipal spraying efforts, health officials recommend residents adopt the "Four Ds" of West Nile prevention:

DEET — Use insect repellent containing DEET, picaridin, or oil of lemon eucalyptus when outdoors

Dress — Wear long sleeves and pants during dawn and dusk when mosquitoes are most active

Drain — Eliminate standing water around your property, including in gutters, flower pots, and bird baths

Dusk/Dawn — Limit outdoor activities during peak mosquito hours

Looking Ahead

The District 10 spraying represents part of an ongoing surveillance and response system that will continue through the summer months. Dallas County maintains an interactive map showing proposed and completed spray zones, allowing residents to track activity in their neighborhoods.

City officials note that while spraying reduces adult mosquito populations, it represents just one component of integrated vector management. Continued public cooperation in eliminating breeding sites and personal protection measures remains essential for reducing West Nile transmission risk.

Residents with questions about the spraying schedule or who wish to report standing water or excessive mosquito activity can contact Dallas County Mosquito Control at 214-819-2115 or visit the county's online mosquito reporting portal.

With summer heat intensifying and mosquito season reaching its peak, health officials expect continued surveillance and targeted control efforts across the Dallas-Fort Worth metroplex in the coming weeks.
