Dallas, TX – Dallas County Health and Human Services announced the fourth human West Nile Virus case in the City of Dallas for the 2013 season. The resident lives in the 75228 zip code and was diagnosed with West Nile Fever. For medical confidentiality and personal privacy reasons, the City of Dallas does not provide additional identifying information.

Mosquitoes that carry the West Nile Virus are here in Dallas and are active. The City’s mosquito control program is continually evolving to address the threat of the West Nile Virus (WNV). The City meets weekly with Dallas County health officials and other municipalities to discuss trapping results, ground spraying applications and best practices. Public information and outreach has been expanded using television, radio, billboards, social media, phone calls, brochures, and community meetings. Additionally, a webpage at has been setup and dedicated to WNV information, including links to videos developed to educate the public on WNV prevention.

Off-season surveillance of mosquito activity was conducted from November 2012 through this past April. With the start of mosquito season in May, the City tripled the number of traps from last year to 90 and placed these traps in fixed locations where previous history indicated WNV activity. As necessary, the City places additional traps in other areas to gain information on mosquito activity.

The City is proactively identifying sources of mosquito breeding by responding to 3-1-1 standing water, stagnant pools and water conservation complaints. City employees have been asked to report standing water and staff has evaluated aerial views of the City to identify potential breeding sources.

The City’s mosquito surveillance program and abatement teams are taking the appropriate action to prevent or eliminate mosquitoes. However, it is important that residents do their part by taking the necessary precautions to avoid exposure to the virus.

People have an important role to play in protecting themselves and their loved ones from illnesses caused by mosquitoes. The best way to avoid exposure to West Nile virus is to avoid mosquito bites by employing the 4 Ds’:

Defend yourself by using insect repellents – Follow label instructions

Dress in long sleeves and pants, loose and light colored clothing when you go outside

Dusk and dawn, stay indoors during this time to avoid mosquitoes when they are most active

Drain standing water and install or repair window screens.

Protection against mosquito bites

Dallas residents are urged to take precautions against mosquito bites by reducing outdoor activity during early morning and nighttime hours. Residents who are outside during these times should cover their arms and legs and use a mosquito repellant.

Prevent mosquito breeding

Residents should eliminate standing water to prevent mosquito breeding and the spread of West Nile Virus. Breeding places for mosquitoes include swimming pools that are not kept clean, stagnant ponds, pet watering dishes, birdbaths, potted plants, old tires, empty containers, toys and clogged rain gutters and French drains. Standing water should be eliminated promptly, as mosquitoes can grow from egg to adult in as little as seven days.

To report standing water or mosquito problems Dallas residents should call 3-1-1. For additional information on Mosquito Control visit

    The best repellent I know of - Greenbug for People. It is safe, natural and very effective at killing and repelling mosquitoes. It is my top recommendation for my patients.
