Re: Notification of Late Evening Aerosol (ULV) Applications

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

May through September Adulticide aerosol (UVL) applications are conducted between sunset through midnight, Monday through Thursday.

If any resident wishes to know when the spray program may be conducted in their area, they should go to the Districts website. If an individual would like to see a map and/ or street listing of the areas to be treated, they should click on following link, and then enter their address.

Please note that the UVL map and /or street listings will be posted on or about 3:30 p.m. the day of the scheduled application . Residents may also contact the following number 1-617-582-6216 after 3:30 P.M the day of the scheduled treatment to receive information detailing the streets/areas to be treated in town.

The purpose of the adultcide application is to control nuisance and/or virus carrying adult mosquitoes. The control product being used is DUET (EPA Reg#1021-1795-8329) applied in ultra-low volume (ULV) sprayers at a rate of approximately one half ounce per acre of finished spray.

WNV is transmitted to humans by the bite of a mosquito infected with the virus. While WNV can infect people of all ages, people over the age of 50 are at higher risk for severe infection. By taking a few common-sense precautions, people can help to protect themselves and their loved ones:

Limit your time outdoors during peak periods of mosquito activity (dusk and dawn) or, if you must remain outdoors, wear a long-sleeved shirt and long pants.

Use a mosquito repellent that contains DEET or Picaridin. Oil of lemon eucalyptus may also be considered. Products with permethrin should only be used on clothing. Always follow the directions on the label. Repellents should not be used on children younger than two months of age. Oil of lemon eucalyptus should not be used on children under three years of age.

Cover up the arms and legs of children playing outdoors. When you bring a baby outdoors, cover the baby’s carriage or playpen with mosquito netting.

Fix any holes in screens and make sure they are tightly attached to all doors and windows.

Remove any standing water from backyards so mosquitoes can’t breed. Mosquitoes will begin to breed in any puddle or standing water that lasts for more than four days. Make sure water does not collect and stagnate in ceramic pots, trash cans, recycling containers, old tires, wading pools, birds baths, etc. Remove leaves and debris that may prevent drainage of roof gutters.

The Norfolk County Mosquito Control Project (NCMCP) continues to conduct weekly ground based spraying on Thursday late evening between sunset and midnight based on resident’s requests and mosquito activity monitoring, weather permitting. Residents who wish to have their property sprayed by NCMCP should fill out an online request form each week or call the office at (781) 762-3681 any day but before noon on Thursdays, to be included in that weeks's application. If any resident wishes to know when the spray program may be conducted in their area, they should go to the Project’s website where map and/or street listings will be posted on or about 3:30 PM each Thursday.

If a resident wishes to be excluded from these area-wide applications they must follow state regulations which include sending a request for exclusion to the Town Clerks's office. A request for exclusion must be made each year. Even if you requested exclusion last year you must do so again this year. More detailed instructions and a link to the state law are available on the Districts website.

More information on mosquito-borne diseases, their symptoms, on protecting yourself from bites by mosquitoes, and on safe application of mosquito repellents can be obtained by visiting the MDPH website on arboviral (mosquito-transmitted) diseases.

In addition, the Milton Board of Health reminds residents to also be aware of the increasing occurrence of Lyme disease in Milton. The highest risk period of infection runs through early fall. The single most important thing is to check yourself for ticks once a day (don’t forget to check children and pets too). For more information please visit the MDPH website on tickborne diseases.


The Milton Health Department would like to advise residents that the Norfolk County Mosquito Control Project (NCMCP) will continue with its comprehensive mosquito control program this spring. The NCMCP’s Integrated Pest Management approach includes waterway management, larval control, and adult control.

The NCMCP will be conducting helicopter applications of the biological larvicide Bti (Bacillus thuringiensis israelensis) to control mosquito larvae. The applications will be conducted over specific large wetlands in 24 communities including the Town of Milton. The applications will take place in April. Applications may continue beyond these dates weather dependent.
