Dallas to Spray for Mosquitoes After Positive West Nile Virus Sample

The City of Dallas says they'll spray for mosquitoes after one of the insects trapped in the 75229 Zip Code tested positive for West Nile virus.

As a result, the town will begin targeted ground spraying in an area generally bounded by North Bend Drive on the north, Grissom Lane on the west, Webb Chapel Road on the east and Flowerdale Lane on the south. (See map below)

Spraying will take place Friday and Saturday, July 10-11, between 9 p.m. and 5 a.m. the following morning.

Ground spraying will not take place in the event of rain or winds greater than 10 mph.

The City of Dallas reminds residents that while the insecticide is approved by the Environmental Protection Agency for treatment, residents in the above areas should avoid contact with the spray by staying indoors. Persons inside a vehicle while trucks are actively spraying should remain in their vehicles with the windows up and the air conditioner on until the trucks pass and the spray is no longer visible.

Persons outside during the scheduled spraying time should be alert for trucks and should not follow them.

Residents who come in contact with the spray are advised to wash the affected area thoroughly with soap and water. The spray breaks down quickly in the presence of sunlight and has no residual effect.

How to Protect Yourself From Mosquito Bites
  • Dress in long sleeves, pants when outside: For extra protection, spray thin clothing with repellent.
  • DEET: Make sure this ingredient is in your insect repellent.
  • Drain standing water in your yard and neighborhood: Mosquitoes can develop in any water stagnant for more than three days.

It has been recommended in the past that to avoid mosquito bites you should avoid being outdoors during Dusk and Dawn (the 4 Ds). While this is true for mosquitoes that commonly carry the West Nile virus, other types of mosquitoes that are more likely to carry Zika, dengue and chikungunya are active during the day. When outdoors, no matter what time of day, adjust your dress accordingly and wear insect repellent containing DEET, picaridin or oil of lemon eucalyptus as your first line of defense against insect bites.
