(Fremont County, Wyo.) - No mosquitos have tested positive for the West Nile Virus so far this year, according to the Fremont County Weed and Pest District.
Assistant Supervisor Nancy Pieropan made another encouraging report on Tuesday. “I tested mosquitoes from the Lander, Hudson and Arapaho areas,” she said in an email. “There are still fairly high numbers of mosquitoes with relatively few Culex.” The Culex are the vector mosquitos that carry the disease.
On Tuesday, in Lander’s City Limits, 98 total Culex were found from three traps in the city, 26 were found inside the Town of Hudson and 28 at the Arapahoe trap location. All three of those locations are where mosquito spraying and larvacide are in use. Numbers of mosquitos are much higher in areas outside of those communities.
Former district supervisor John “Lars” Baker, who retired at the end of last year, is now working part-time for the district, and he is trapping mosquitos in the Riverton area. He told the Riverton City Council Tuesday night that the West Nile virus has been in Fremont County for about a decade. “It’s endemic here,” he said. He also said people with compromised immune systems are more prone to become very ill with the disease and its side effects. “It can be fatal.”
Baker called the Culex “a sneaky mosquito” that generally avoids people who are active. “it’s habit is to come inside when people enter a leave a house and hang around until you sleep and it then takes a blood meal.” He said the Culex are not the skeeters that can drive a person nuts while on a picnic, “those that fog around you.The Culex is a sneaky mosquito, and you have to pay attention to that.”
