The Cache Mosquito Abatement District (CMAD) announced that mosquito samples collected in Newton have tested positive for West Nile virus. The confirmation was provided by the Utah State Public Health Laboratory.
While there is a vaccination available for horses, there is no vaccination for humans against the West Nile virus.
In response to the positive test, CMAD will continue its surveillance and abatement programs. The primary method used for mosquito control is larviciding, which targets larvae before they reach maturity. Adulticiding via fogging is performed only at night when Culex mosquitoes, which are known carriers of West Nile virus, are most active.
In collaboration with the Bear River Health Department, CMAD recommends several precautions to help residents reduce exposure to mosquitoes.
Residents are encouraged to use EPA-registered insect repellents containing ingredients such as DEET, permethrin, picaridin, IR3535, or oil of lemon eucalyptus. It is also advised to wear long sleeves and pants between dusk and dawn when mosquitoes are most active.
To further reduce mosquito populations, officials suggest eliminating standing water around homes in items like tires, buckets, pet dishes, and plant trays. Other recommendations include maintaining clear roof gutters, cleaning or draining swimming pools regularly, and ensuring window and door screens are in good repair.
Additionally, trimming tall grass and weeds is advised as these areas serve as resting places for adult mosquitoes during the day.
