Cache Mosquito Abatement District (CMAD)


Abatement activities began in early May. Larvicide (chemicals that target only mosquito larva) is being applied to areas of standing water when mosquito larva are found. Fogging to control adult mosquitoes began June 11th. Please call (435) 764-6839 to report mosquito problems.

We use GIS (Geographic Information System) to track where we find mosquito larva, what compound we use to treat the standing water, and to record the results when we check back (larval growth stopped, larva dead, etc.). All of our foggers are equipped with a GPS chip to not only track our route but to also gather information on the application rate, speed of the vehicle, and to stop fogging when we reach those properties that have requested no spraying (fogging). The foggers are calibrated to deliver a consistent droplet size at various travel speeds up to 20 mph. All of our workers are licensed by UDAF (Utah Department of Agriculture and Food) to apply pesticides.
