West Nile Virus found in Cache Valley

Cache County: The Cache Mosquito Abatement District has been informed by the Utah State Public Health Laboratory that a recent mosquito samples tested positive for West Nile virus in the county.

The West Nile Virus has been confirmed in a mosquito trap in Amalga.

The Cache Mosquito Abatement District (CMAD) will continue abatement and surveillance activities. 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.


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.
