Mosquito Update

2021 Season Update

You have found the location for frequently updated information on mosquitoes and their control in Teton County, Wyoming. Look to this page for updates on ultra-low volume (ULV) spraying for adult mosquitoes in your area. Please note:  We do not spray adult mosquitoes for special events. All of our control work is based on surveillance data. To determine the need for adulticiding, we set a trap to see how many mosquitoes are in an area. If the number of mosquitoes caught in the trap does not meet minimum action thresholds, we will not spray for adults. If you would like to hire one of the local contractors to spray before your special event, the list can be found here.


Summer 2021: 

Week of July 26: There are no truck mounted ULV treatments for adult mosquitoes scheduled at this time.
