The Cascade County Weed and Mosquito Division has confirmed a mosquito pool has tested positive for West Nile Virus last week. The positive mosquito pool was detected in Fort Shaw just 25 miles from Great Falls. Despite no confirmed cases in humans, Cascade County health officials encourage residents to protect themselves. The CDC suggests the following:
Avoid Mosquito Bites
Use insect repellents when you go outdoors. Repellents containing DEET, picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol products provide longer-lasting protection. To optimize safety and effectiveness, repellents should be used according to the label instructions.
More information about insect repellents can be found here.
When weather permits, wear long sleeves, long pants, and socks when outdoors. Mosquitoes may bite through thin clothing, so spraying clothes with repellent containing permethrin or another EPA-registered repellent will give extra protection. Don't apply repellents containing permethrin directly to skin. Do not spray repellent on the skin under your clothing.
Take extra care during peak mosquito biting hours. Take extra care to use repellent and protective clothing from dusk to dawn or consider avoiding outdoor activities during these times.
Mosquito-Proof Your Home
Install or repair screens on windows and doors to keep mosquitoes outside. Use your air conditioning, if you have it.
Help reduce the number of mosquitoes around your home by emptying standing water from flowerpots, gutters, buckets, pool covers, pet water dishes, discarded tires, and birdbaths on a regular basis.
