GRAPEVINE — The City of Grapevine administered ground spraying last week after receiving confirmation that three local mosquito samples had tested positive for carrying the West Nile virus.Positive samples were found in the 1700 block of Northwest Highway, 1500 block of N. Dooley Street and 2500 block of Briarwood Drive. The areas sprayed covered a half-mile radius from the sample sites.Grapevine follows Tarrant County’s recommendations for ground spraying when West Nile virus samples test positive. Residents are notified in advance about spraying through a Code Red phone call, the city’s website, Facebook and Twitter.The county’s first positive sample for West Nile was reported June 27 in Grapevine, about three weeks later than last year.Grapevine sprayed for mosquitoes a day after the June positive test was confirmed at a trap in the 300 block of West Dallas Road, near the police station. In an effort to combat the virus this year, Grapevine, in conjunction with Tarrant County and neighboring cities, is taking a proactive stance to prevent the spread of the virus by doing the following:• Increasing the number of mosquito traps for testing from two to five at fixed locations and one floating location that can be used to assess other areas.• Testing weekly instead of every other week.• Testing earlier in the season and testing longer.• Following efforts of past years to hand out mosquito larvicide dunks that can be placed in standing water to kill larvae. The dunks can be obtained in Parks and Recreation administration at City Hall at 200 South Main Street or at the Municipal Service Center at 501 Shady Brook Drive.• Starting the public education process earlier 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, call 817-410-3330. Tarrant County Public Health officials eight pool samples in the county have tested positive for West Nile virus as of Aug. 8.
