Adulticiding/ Fogging on private property will be based on need rather than want. Requests for fogging will result in trap placement on/around the property and or adjacent lots. We use numbers collected from our traps to determine the level of infestation. If the trap(s) counts meet or exceeded  the thresholds set by the District (50 or more Aedes spp.  and/or 5 or more (Vector) Culex ssp.) supplemental treatment options will be considered.  If traps indicate that current fogging routes are sufficiently abating mosquitoes no supplemental treatment will occur.  All of our actions have to be justified to the EPA and the Idaho Department of Agriculture. So we will not break the law because one "feels" like were not doing enough. The public served by the District need and deserve an agency whose commitment to pursuing public interest outweighs any competing personal or political considerations

Budget Hearing Date for FY-2024 is Wednesday August 2nd, 2023 before the start of the regular scheduled meeting(5 PM).


The Edwards Mosquito Abatement District’s control programs will begin on May 8th, 2023. Abatement activity will be conducted within the mosquito abatement taxing district, roughly located around the northern portion of Lake Cascade. Larval mosquitoes will be controlled in non-residential areas by air this year using an unmanned aerial system or drone. Flights will be conducted in areas such as marshes, cattail swamps, woodland pools, flooded fields, and other large and difficult areas to access. Roadside ditches, snowmelt/storm water flooded basins and other shallow, stagnant bodies of water in residential areas will be conducted on foot with backpacks as necessary. Areas with flowing waters (streams, rivers) or deep waters (ponds, lakes) typically do not support mosquito breeding and will not be treated. The primary control agents will be larvicides called VectoPrime FG (Bti) a quick release granule bacterium fused with a growth regulator and MetaLarv (growth regulator). Applications to control mosquito larvae will continue as needed until September,1 2023. Control Agents will only be applied where larvae are collected. Street spraying by truck-mounted sprayers will be completed in the community residing within the Edwards Mosquito Abatement District; other communities may choose to do so as well if a public health emergency dictated by the State of Idaho. Street spraying (fogging) is not regularly scheduled as it is dependent upon favorable weather conditions ex. wind less than 10 MPH, temps at dusk greater than 50°F and elevated biting mosquito populations and/or disease presence determined by traps placed throughout the district. PermaSease 4-4 (RTU) ULV Insecticide (Permethrin + Piperonyl Butoxide (PBO)) will be utilized in truck sprayers. The District may decide to complete barrier insecticide (bifenthrin) applications to resident’s private property where larval/adulticide applications fail to provide adequate control as well parks, athletic fields, schools, and other public areas should a public health emergency dictate. Persons wishing their properties would not be treated must contact the Edwards Mosquito Abatement District and fill out a “Request for Non-treatment”. Otherwise, properties may be treated as necessary. Information on biological control agents, insecticides, areas likely to be sprayed or any potential hazards is available on our website www.emad-donnelly.org under the resources heading or upon request.
