Two trapped mosquitoes test positive for West Nile Virus

Post Date:10/11/2017

The City of Keller has been notified by the Tarrant County Public Health Department that two mosquito samples from within the city limits have tested positive for West Nile Virus. In response, ground spraying has been scheduled around the trapping sites at 7000 Shady Grove Road and 8700 Davis Blvd.

This is the third positive test at the Shady Grove site this year, the most recent of which occurred the week of Aug. 21, and the second positive test at the Davis site, the most recent of which occurred the week of July 17. 

In accordance with the city’s Mosquito Abatement policies and recommendations from Tarrant County Public Health, ground spraying will take place near the collection sites the evenings of Thursday, Oct. 12 and Friday, Oct. 13, 2017. Efforts will target roads and public land within a half-mile of the trap collection site.

The contractor will be using water-based insecticides that offer low toxicity, low odor, rapid biodegradation and high mosquito mortality. Activity will happen between 9 p.m. and 5 a.m. both nights, while mosquitoes are active and winds are slow.
