(Riverton, Wyo.) – In one of the most active mosquito habitats outside of Riverton, Fremont County Weed and Pest District Supervisor John “Lars” Baker told County10.com on Tuesday that one trap collected some 6,000 mosquitos in one overnight period this month. “One night, 6,000 mosquitos,” Baker said, of a trap located off of North Smith Road on Riverton’s east side. The road sits in close proximity to the Big Wind River.
The high number of mosquitos along the outskirts of the city limits promoted city officials to increase spraying in those areas to a third night this past week. The extra spraying apparently had a positive impact as only 900 mosquitos were captured at that location this week, which is still a high number of the skeeters.
“Mosquitos have been really tough in Riverton the last three months, but I went out last night and didn’t see any.” Baker, however, was walking in an area of town where the city fogs for mosquitos. “We are still recording high west nile virus counts in mosquitos we are trapping. People need to protect themselves,” he said.
In the weekly mosquito report issued by the district’s Biological Control Specialist Nancy Pieropan on Wednesday afternoon, the 6,000 mosquito count was credited to one night’s trapping on August 14th. Today’s report said the latest mosquito count from that same location was 900 insects. By comparison, Riverton’s two other trap locations collected 19 and 20 mosquitos each this week, at Davis Lane and along Jackson Street, respectively.
One location in Lander showed a high count of virus in captured mosquitos, that also on the outskirts of town, near the city’s sewer ponds off of North Second Street. The number of mosquitos trapped there was not available. The St. Stephen’s Mission on the Wind River Indian Reservation also showed a high WNV count among the 600 mosquitos counted at that location.
The “5 D’s” of prevention include:
1) DAWN and 2) DUSK – Most mosquito species prefer to feed at dawn or dusk, so avoid spending time outside during these times.
3) DRESS – Wear shoes, socks, long pants and a long-sleeved shirt outdoors or when mosquitoes are most active. Clothing should be light-colored and made of tightly woven materials.
4) DRAIN – Mosquitoes breed in shallow, stagnant water. Reduce the amount of standing water by draining and/or removing it.
5) DEET – Use an insect repellent containing DEET (N, N-diethyl-m-toluamide). When using DEET, be sure to read and follow the label instructions. Other insect repellents such as Picaridin (KBR 3023) or oil of lemon eucalyptus can also be effective.
