Two mosquito samples collected from traps earlier this month in Williamson County have tested positive for West Nile Virus, the City of Georgetown and Williamson County and Cities Health District said.
The species of mosquito that tested positive for West Nile was Culex quinquefasciatus, also known as the Southern house mosquito. Both the city and WCCHD said the mosquito has a flight range of about one mile.
The city said one positive sample was collected from a trap in the Villages of Berry Creek neighborhood (near Interstate 35 and Texas 195) on Oct. 18, and that there were 44 Culex mosquitoes in the sample. The city did not know how many of those mosquitoes were carrying West Nile.
Georgetown said spraying is scheduled in the vicinity of the trap since children and families will be out for trick-or-treating next week. Spraying of a permethrin-based insecticide will take place after 9 p.m. on Oct. 26-28 “along the street right-of-way and in public parks, weather permitting.” Permethrin is a synthetic derivative of pyrethrum, which is found in Chrysanthemum flowers, the city added. A map of the area set to be spray is embedded at the bottom of this story.
WCCHD said the second positive sample was collected from a trap in a park near FM 1431 and County Road 175 on Oct. 13. This location is in the vicinity of Southwest Williamson County Regional Park and several neighborhoods, but WCCHD did not specifically say in which park the trap originated.
The health district is encouraging everyone to take the necessary precautions to protect themselves from mosquito bites and to prevent mosquito breeding on their property. Both the city and WCCHD are using larvacide tablets to treat standing water found on public property.
