Re: Notification of Late Evening Aerosol Applications (Ultra Low Volume – ULV)

Please be advised that the Norfolk County Mosquito Control District will begin the 2017 late evening ULV aerosol applications on or about May 30, weather permitting.

May 30 through September 29, 2017 - Adulticide aerosol (ULV) applications.

(Conducted between sunset and midnight, Monday through Thursday)

If any resident wishes to know what day of the week spraying may be conducted in their town, they should go to the Districts website at  After the ULV program begins, if an individual would like to see a map of areas to be treated on the day of application, they can go to that same link, and then enter their address in the address line of the interactive map.

Please note that the ULV map will be posted on or about 3:30 p.m. the day of the scheduled application.  Residents may also contact the following number 617-582-6216 after 3:30 P.M. the day of the scheduled treatment to receive information detailing the streets/areas to be treated in the town.

The purpose of the adulticide application is to control nuisance and/or virus carrying adult mosquitoes.  The control product being used is Zenivex (EPA Reg. No. 2724-807) applied in ultra-low volume (ULV) sprayers at a rate of approximately one ounce per acre of finished spray.
