Mosquito numbers continue to drop; No WNV detected this week
(Lander, Wyo.) – More good news from the Fremont County Weed and Pest Department this week. Assistant Supervisor Nancy Pieropan again this week said “there was no indication of West Nile Virus (WNV) in Fremont County. The numbers of mosquitoes continue to drop and there are very few Culex being trapped.”
Culex is the species of mosquitoes that carries the virus.
Two pools of trapped mosquitos in Lander produced only 32 mosquitoes with only six Culex. One pool in Hudson numbered 45 mosquitos with only two Culex. On Snavely Lane, between Lander and Hudson, and an area that is not fogged for mosquito control, 830 mosquitoes were trapped, and not one of them was a Culex.
There was no report from Riverton this past week. So far this spring and summer, out of 101 West Nile virus tests, only one location tested positive for the disease, and that was at all mosquito monitoring locations August 14th in Riverton. Since that time, the City of Riverton has been fogging each of five zones within the city twice each week.
