Fogging Application


Fogging was initiated in the area immediately north of the city of Aberdeen.  Fogging will continue in the Aberdeen and McTucker Ponds area Thursday, September 7, 2006.  Fogging will then be done in the Firth area.  The time table for fogging other areas has not yet been established.


Fogging involves the use of a machine which emits the pesticide in fog form.  The machine is placed in the back of a pickup.

The benefit of fogging is that it can target specific smaller locations and is more cost effective than aerial spraying on a frequent basis for small areas.  Fogging is intended to be a measure that would occur between necessary aerial applications.  Fogging is being considered for areas of public gatherings such as sporting events, recreational parks and the Eastern Idaho State Fair.  The fogging would take place at times when people would not be present, preferably 48 hours or more prior to the events.  The public will be notified if fogging has occurred at a location prior to the event.

The areas to be targeted will ideally be selected based on data showing areas of need (high mosquito trap rates, response to citizen complaints about mosquito nuisance, clusters of indigenous West Nile Virus confirmed human cases, areas particularly suited for breeding).  The amount of area to be sprayed will be largely affected by the cost of conducting spraying and the amount of funds available to conduct the spraying.


Bingham County's plans to conducting fogging of an adulticide itself, not by using a private company.  The spraying is being conducted following training by the Department of Agricultural.  Application is being made based on product labels and manufacturer recommendations.


The chemical to be used is Kontrol 4 - 4.  You can read information about Kontrol 4 - 4 by clicking on this link.  The insecticide is approved for use by the Idaho Department of Agriculture.


Fogging can be delayed or interrupted during during periods of high wind or if it is raining.

Fogging will begin at approximately 6:00 p.m. in the evening and can continuing until approximately 1:00 a.m. depending on meteorological conditions.

The application will be done with a fogging machine which will be placed in the back of a pickup or towed on a flatbed trailer.  The fogger will be moved or towed at from 10 to 25 miles per hour.

If you are interested in knowing if your particular property will be subject to fogging , please continue to check back to this web page for updated information and publishing of the map showing the fogging area.  If you are unclear whether your particular property is contained in the fogging area or if you have a request to be included in the fogging area, please contact the Department of Homeland Security at 782-3190 or 782-3191.


The County will consider and accommodate any reasonable request for no-spray zones.  Such requests might include, but are not limited to:

  • Apiaries and farmers using insect pollinators

  • Organic farmers

  • Fish farmers

  • Aviaries and avian rehabilitation centers

  • Nature Centers

  • Zoological gardens (city or county zoos)

If you desire to request to included in a no-spray zone, please contact the 
Bingham County Department of Homeland Security
 at 782-3190 or 782-3191. 


Since no pesticide can be considered 100 percent safe, pesticide applicators and the general public should always exercise care and follow specified safety precautions during use to reduce risks.

  • Plan for you, your family and pets to stay indoors, if possible, during pesticide spray events.

  • Close your windows prior to pesticide spraying in your area.  Before evening spraying, close windows and leave them closed overnight.  Also close automobile windows and leave them closed.

  • It is okay to use home air conditioning because it re-circulates air inside the home and does not bring air in from outside.  If you are driving in your car during an aerial spray event, keep you windows closed and make sure your vents are set to re-circulate air inside the car.

  • Take precautions to avoid pesticide residues that may be left after a spray. Take shoes off at the door.  Wipe your pets' paws when they come into the house.  Wash your hands thoroughly after handling or touching foliage in the garden.  Wash vegetables from your garden and move children's toys indoor or into the garbage.  For larger toys, cover any area that children will contact directly with a tarp.

  • If a park or public area (playfield, playground, etc.) has been sprayed, consult local officials if you are unsure whether it is okay to return to that area following a spray event.

The duration of the above precautions will depend upon the nature of the chemical(s) sprayed.  Information about the chemical(s) and their persistence will be provided through this web site.  Each chemical is identified for each type of application - aerial, fogging, and water-based.  Information about each chemical can be accessed the part of each web page that discusses the chemical being used.
