The City of Grapevine is working with Tarrant County Public Health in responding to imported cases of the Zika virus. As of late June 2016, there have been no cases of locally transmitted (via mosquito) Zika cases in the U.S. There have been numerous imported (illness acquired outside of the U.S.) cases of Zika in North Texas, however.
In an effort to prevent the potential localized transmission of the Zika virus in Grapevine. The City, in conjunction with Tarrant County, has increased monitoring of populations of Aedes mosquitoes, the Genus of mosquito that is known to transmit the Zika virus in other countries. This mosquito has different habits than those that carry WNV in that they actively hunt in the daytime (not just dusk and dawn) and they primarily feed on humans (Culex mosquitoes primarily feed on birds). Aedes mosquitoes are weaker flyers than Culex mosquitoes, so they tend to hang around where people are, not straying too far away.
Additionally, residents can help protect themselves by following a modified version of the WNV protection Four D's (see below), including:
- 1. If you must be outside, where light color clothes and cover as much of your body as possible.
- 2. Use a bug repellent containing DEET at all hours of the day, not just dusk and dawn.

Grapevine, in conjunction with Tarrant County, continues to take a proactive stance to prevent the spread of West Nile Virus with the following measures:
- Mosquito trap testing at five fixed locations. Trap testing at one "rotating" site (new spot each week) that is used to assess areas of concern.
- Testing mosquitoes weekly for West Nile Virus (WNV).
- Sampling and testing April through November.
- Offering mosquito larvicide (kill mosquito) "dunks" to residents to place in standing water. The dunks are available at our Municipal Service Center (501 Shady Brook Drive).
- Continuing the public education process and participating with Tarrant County and other cities in that effort.
- Actively monitoring public property for standing water and enforcing regulations against standing water on private property. To report standing water, please call 817.410.3330.
- In the event of West Nile Virus positive samples, we follow Tarrant County Public Health recommendations for ground spraying.
- In the event that we spray, residents are notified via Code Red phone call, the website, Facebook and Twitter in advance. To register to be notified via Code Red, please complete this form: http://bit.ly/1w48zKt.
Spraying Adulticides takes place in areas where vector mosquito(s) are detected to have tested positive for the West Nile Virus.
