A mosquito caught in a Taylor trap has tested positive for West Nile virus, according to a release from the city of Taylor.

Taylor is located in eastern Williamson County, in close proximity to Pflugerville, Hutto and Round Rock.

A second trap, collected in Granger, also contained a mosquito that tested positive for the virus.

Round Rock and Pflugerville do not spray for mosquitoes, according to each city’s website, because of environmental impact concerns. It is unclear whether the city of Hutto sprays for mosquitoes. However, Williamson County will be spraying in Taylor, according to a separate release from the county.

The testing of mosquitoes is part of Williamson County and Cities Health District’s Integrated Vector Program, which is intended to prevent the spread of diseases carried by mosquitoes such as the West Nile and Zika viruses.


The Taylor sample was taken from a trap located near Murphy Park on Veteran’s Drive, according to the release. The city’s press release states this is the first time a positive sample has been taken from this location.

Insecticide spraying will take place overnight July 2 and 3 within a mile of the sample site with a pyrethrin-based compound sprayed along the street and in public parks. Pyrethrin is a natural compound that can be found in chrysanthemums, the release stated.

The cities of Round Rock and Pflugerville recommend on their websites the use of mosquito spray containing deet as an active ingredient; avoiding the outdoors during dusk and dawn, when mosquitoes are most active; draining stagnant water; and dressing in clothing that covers the skin to avoid being bitten by the insects. The city of Hutto does not have a webpage with advice regarding mosquitoes.
