Mosquito Management Program & Information

Mosquito Control 

During mosquito season Dallas County Health and Human Services Department (DCHHS), set out weekly mosquito traps in seven (7) zones known as Mosquito Management Areas (MMA). Each MMA has been carefully defined to optimize our resources. Rowlett EH works alongside DCHHS to conduct surveillance and larvaciding areas containing stagnant water.

Testing and Monitoring

During the high activity months of mosquito season, Environmental health works along with Dallas County Health and Human Services Department (DCHHS), to conduct testing and surveillance of the local mosquito population for the West Nile Virus.

In the event that the West Nile Virus is detected, the following will occur:

  • Advise the public and emphasize source reduction, personal protection and disease symptoms
  • Ground-based spraying will occur (weather permitting) in the MMA where the positive mosquito sample was found.

When ground spraying is to occur, it will be documented and placed on the Rowlett Facebook page, and updated on the City Website as soon as information is available. Citizens within the spray area will also be notified by Connect Rowlett at 6:30pm each night of spraying.

Control Methods

The City of Rowlett’s Mosquito Action Plan, was developed to provide guidelines which help prevent and control mosquito-borne diseases. This integrated approach to mosquito control includes public education, source reduction, and larviciding. It is important to stop adult mosquitoes’ ability to spread disease by eliminating breeding and harborage locations, such as standing water.

Please notify Environmental Health of standing water, stagnant swimming pools, or other mosquito concerns by calling (972) 412-6125 or emailing at Healthservices@rowlett.com
