Parks and Recreation Director Todd Feezer said despite the city finding the two samples of West Nile, the risk of West Nile virus infection is still quite low.
West Nile virus is spread by mosquitoes that feed on infected birds, such as the woodpecker found in Laramie July 20, then bite people, animals or other birds.
Full residential fogging may return based on a mosquito control evaluation following completion of fogging and examination of trap data and RAMP testing results.
Keith Wardlaw, Mosquito Control Crew Supervisor, says recent mosquito trapping has turned up a few vectors of West Nile -- three mosquitos, to be exact, out of the 20,000-30,000 trapped.
The chemical currently used in mosquito control fog trucks will be replaced with Zenivex, which the Environmental Protection Agency recognizes as a “Reduced Risk Pesticide.”
