West Nile Virus Confirmed in Cache Mosquitoes

Mosquitoes that were trapped in Amalga, Benson, and Mendon on August 1st tested positive for West Nile Virus (WNV). Nibley had WNV-positive mosquitoes that were trapped on August 8th. On August 19th, Logan City mosquito abatement reported that WNV was confirmed in mosquitoes it had trapped. West Nile Virus has also been found in mosquitoes from Box Elder, Carbon, Davis, Duchesne, Salt Lake, Uintah, Utah, and Weber mosquito abatement districts. Twenty-two human cases of WNV (most in Salt Lake County) have been confirmed as of September 11th with one death.

Please be aware of the importance for personal protection when outside. The mosquitoes that carry WNV are active from dusk to dawn. Wear long sleeves and pants and use an approved mosquito repellent Drain standing water.

Mosquito Activity

Fogging to control adult mosquitoes continues throughout the District. Please refer to our fogging schedule to find out when we will be in your area. Fogging occurs after sunset to around 1:00 a.m. when Culex mosquitoes (the ones that carry West Nile Virus) stop flying. Workers continue to monitor mosquito activity via mosquito traps and test standing water for mosquito larva.
