Neighborhood fogging for adult mosquito control may start in spring as nighttime temperatures permit. Your neighborhood may be subject to U.L.V. treatments.

Facts About U.L.V. Fogging

Adulticiding (ULV Fogging) is controlling mosquitoes in their adult (flying) stage. Mosquito Adult control products rapidly reduce the flying-biting mosquito population. Adulticiding may be initiated when there is evidence of significant populations of mosquitoes in a region if there is evidence of mosquito borne diseases in the County (West Nile virus or WNv).

The most common method of mosquito adulticiding is known as Ultra-Low-Volume (ULV) spraying. ULV spraying is the process of distributing very small amounts of liquid into the air as a fine mist droplet. Typically, less than a "shot glass" of product is dispersed over an area the size of football field (approx. 1 acre). The droplets float over the air currents and quickly reduce the numbers of mosquitoes that come in contact with them. ULV adulticides are applied when flying mosquitoes are the most active, which is typically early evening or pre-dawn.

At this time, CCMAD uses the adult mosquito control product brand named "Duet," which is a combination of two products: Sumithrin and Prallethrin. Duet produces what is called "benign agitation," which brings adult mosquitoes out from a resting state to active flight. Another product that is primarily used is called DeltaGard with the active ingredient Deltamethrin. For more information on these two adult mosquito control products please visit our Label and SDS sections.

CCMAD ULV operations are applied with truck-mounted application equipment that is capable of distribution of the "fog" material over a wide area. Sometimes, small localized applications are made with handheld, backpack application equipment. To assure proper distribution of droplets, application equipment is calibrated using computerized measurement tools at least once a year.

In the event of a potential disease outbreak, CCMAD contracts with an outside company with specialized equipment to aerial apply ULV products over a wide area (20,000 acres or more).

If you wish to opt-out of ULV treatments or for pre-notification of treatments in your area or neighborhood, please call our office at 208-461-8633 or fill out a service request from our webpage and provide us with details of your location and contact information. If you have honey bees or other types of bees then please call our office for bee protection advice.

To Protect Honey Bees

Call us at 461-8633 to notify us of active honey bee colonies, so we can create a no-spray zone.
