Riverton mosquito traps all test positive for West Nile Virus on Monday

(Lander, Wyo.) – Seven pools of trapped mosquitos were tested overnight for the West Nile virus, and the only ones to come back positive were all in Riverton.

“The Riverton mosquito pool tested very positive (>640, as high as the tester goes) for West  Nile Virus,” reported assistant Fremont County Weed and Pest Control Supervisor Nancy Pieropan. “The positive pool included Culex mosquitoes from all three Riverton traps. The other six mosquito pools all tested negative for the WNv.”

The three traps where WNv was recorded were on Davis Lane, North Smith Road and Jackson.

Other pools tested were in Lander, Hudson, Snavely Lane, and Arapahoe.

Pieropan said of 88 tests conducted so far this summer, up until this week’s Riverton results, all had been negative for the virus.

The following mosquito bite prevention measures are from the Centers for Disease Control:

Insect repellent: What you need to know

No one is safe from West Nile virus, but there are steps you can take to help prevent West Nile virus infection.

  1. Apply insect repellent on exposed skin and clothing when you go outdoors. Use an Environmental Protection Agency (EPA)-registered insect repellent. Permethrin sprayed on clothing provides protection through several washes. Don’t spray repellent on skin under clothing and don’t use permethrin on skin.
  2. Cover up! Wear long sleeve shirts and long pants and socks while outdoors to prevent mosquito bites.
  3. Avoid mosquitoes. The mosquitoes that spread West Nile virus bite between dusk and dawn. Limit the amount of time you spend outdoors during these hours. If you are outside, be sure to wear repellent and protective clothing.
  4. Support your local community mosquito control programs. Mosquito control activities are most often handled at the local level, such as through county or city government. The type of mosquito control methods used by a program depends on the time of year, the type of mosquitoes to be controlled, and the habitats where the mosquitoes live. Methods can include eliminating mosquito larval habitats, applying insecticides to kill mosquito larvae, or spraying insecticides from trucks or aircraft to kill adult mosquitoes. Your local mosquito control program can provide information about the type of products being used in your area. Check with your local health department for more information.

What insect repellent should I use?

CDC recommends a variety of safe and effective repellents for you and your family. There are those that can protect you for a short while in the backyard or a long while in the woods.

Look for these active ingredients recommended by CDC and EPA:

  • DEET
  • picaridin
  • IR3535
  • plant-based oil of lemon eucalyptus

Pick your favorite insect repellent and use it whenever you go outside!

All contain an EPA-registered active ingredient and have been evaluated for efficacy and safety. EPA has a long listing of every registered repellent brand in the U.S. There are safe and effective repellents for every budget, age and preference.

    Riverton needs to get on the ball and spray then. Spray ALL neighborhoods. For some reason they shut off the sprayer when they get to our block, just like lastnite! Noone in the block has requested they not spray either.

    I have west nile virus it sucks big time… there is no cure for this.. if you get flu like symptoms get to the doctor don't mess with this… each person is effected differently it picks the weakest part of your immune system…ie like asthma get worse, or eye-site, and so on..
