PETERSBORO – The West Nile virus has been confirmed in a mosquito trap in Cache County.
“Out of sixteen traps we have in the valley, the one in Petersboro tested positive,” according to Cache County Mosquito Abatement District (CMAD) manager, Richard Rigby.
Traps are set each Monday night and picked up the next morning, Rigby said. “If we find the species that carries the West Nile Virus we put them in a vile and send them down to the state health lab.”
The lab results came back positive and the state then notified the county through email.
“We are about three weeks behind last year’s testing positive, which is a good thing,” said Rigby, “but last week’s did test positive in Petersboro.”
Rigby said there are a number of precautions you can take to avoid coming in contact with mosquitoes and the Bear River Health Department recommends:
• Use a mosquito repellent with DEET, permethrin, picaridin, IR3535 or oil of lemon eucalyptus according to package directions.
• Drain standing water in yards (old tires, potted plant trays, pet dishes, toys, buckets, etc.).
• Wear long sleeves and pants between dusk and dawn.
• Keep roof gutters clear of debris.
• Clean swimming pools often or drain them.
• Make sure screen doors and window screens are in good condition so that mosquitoes cannot get indoors.
• Keep weeds and tall grass cut short; adult mosquitoes look for these shady places to rest during the hot daylight hours.
The CMAD will continue abatement and surveillance activates, according to a press release. Abatement consists of primarily larvicide, killing or preventing larva from becoming adult mosquitoes. Adulticide, or fogging, occurs only at night when the Culex mosquitoes (the ones carrying WNV) are active.
Cache County is one of a number of counties in Utah reporting mosquito populations carrying West Nile virus.
Officials in Davis, Salt Lake, Sevier, Uintah and Weber counties have found mosquito populations with the virus.
West Nile Virus can be deadly and can cause symptoms such as fever, headache, drowsiness and nausea.
