Bannock County Mosquito Abatement District operates the Adult Mosquito treatment program primarily based on surveillance results.  When adult mosquito trap counts reach pre-determined thresholds, Bannock County will send fogging trucks to control adult mosquito populations.  In some situations, a barrier spray may be the best choice for control.

Although we try to follow a general schedule to effectively cover all areas of the District, sometimes an adjustment is necessary to address a large hatch-off or infestation.  Service Requests from County residents also impact the treatment program schedule.  Weather and other environmental conditions play a very important role when determining whether or not to fog.

FACTS ABOUT U.L.V. FOGGING

• U.L.V. means Ultra Low Volume. Less than 1.75 ounces are used per acre with very small droplets.
• Because of the low amounts of material used, beneficial insects such as lady bugs, damsel flies and honey bees are not harmed. Flying mosquitoes are the target.
• In most cases, the adult flying mosquito control material used is Permithrin. Permithrin is short lived and breaks down within a few hours and in sunlight.
