West Nile Virus Detected in Cache County Mosquitoes
Cache County, UT – The Cache Mosquito Abatement District (CMAD) has received
confirmation from the Utah State Public Health Laboratory that mosquito samples collected in
Cache County have tested positive for West Nile virus (WNV).
The infected mosquito pool was collected in the area of Newton. In response, CMAD will
continue its comprehensive surveillance and abatement efforts. The primary method of mosquito
control remains larviciding, which targets mosquito larvae before they mature. Fogging
(adulticiding) is conducted only at night when Culex mosquitoes—known carriers of West Nile
virus—are most active.
In collaboration with the Bear River Health Department, CMAD encourages residents to take the
following precautions to reduce mosquito exposure:
• Use EPA-registered insect repellent containing DEET, permethrin, picaridin, IR3535,
or oil of lemon eucalyptus as directed.
• Eliminate standing water around your home (e.g., in buckets, tires, pet dishes, plant
trays, and toys).
• Wear long sleeves and pants between dusk and dawn, when mosquitoes are most active.
• Maintain roof gutters, keeping them clear of debris.
• Clean or drain swimming pools regularly.
• Ensure all window and door screens are intact and in good repair.
• Trim tall grass and weeds, which serve as resting places for adult mosquitoes during
daylight hours.
