AnvilŪ
10+10 (sumithrin)
The
product name of the mosquito adulticide used by the Project in ULV (Ultra Low
Volume) sprayers is called AnvilŪ. It is a combination of two ingredients, sumithrin
(10%) and piperonyl butoxide (10%). Sumithrin is a synthetic pyrethroid, and
piperonyl butoxide is a synergist (a chemical that enhances the ability of
another), allowing sumithrin to control the adult mosquitoes at a lower
concentration. It is sprayed from the truck at 1.9-3.8 ounces per minute, at
a vehicle speed of 5-15 miles per hour. This presents a minimal risk to
humans, pets and non-target species. Anvil 10+10 is an insecticide that
contains synthetic pyrethroids, which emulate naturally occurring
insecticides known as pyrethrins, found in chrysanthemum flowers. This
substance, called d-Phenothrin (brand name Sumithrin), kills mosquitoes
effectively, yet biodegrades rapidly in the presence of sunlight and/or
microorganisms.
Adulticiding
with AnvilŪ
The Project
conducts an early evening spray program which runs from approximately
Memorial Day to Labor Day. During this time the mosquito is actively seeking
a blood meal, and spraying at this time allows us to control the adult
mosquito with a minimal risk of exposure to the public. Weather and mosquito
populations determine the actual beginning and end of our spray program.
The type of
spraying practiced by the Project is called "ULV" spraying. ULV is
an abbreviation for ultra low volume, a method of spraying which
allows us to control adult mosquitoes, and be as environmentally sensitive as
possible. The spray machines are mounted on the back of pickup trucks, and
the applicator drives the vehicle in the area to be sprayed. The vehicle
operator controls the spray from inside the vehicle, without needing to shut
down the spray machine. These applications are based on public request only,
and the Field Technician confirms the presence of a mosquito problem by
conducting a landing count.

Precautions
to observe during a spray application
Generally,
there is no need to relocate during mosquito control spraying. The pesticides
have been evaluated for this use and found to pose minimal risks to human
health and the environment when used according to label directions. Although
mosquito control pesticides pose low risks, some people may prefer to avoid
or further minimize exposure. Some common sense steps to help reduce possible
exposure to pesticides include:
- Listen and watch for announcements about
spraying in the local media and remain indoors during the application to
the immediate area.(please remain inside for 15-20 minutes, or longer
at your discretion)
- People who suffer from chemical sensitivities
or feel spraying may aggravate a preexisting health condition, may
consult their physician or local health department and take special
measures to avoid exposure. (please notify CMMCP to be placed on the
"No Spray" list - 508.393.3055 or e-mail)
- Close windows and turn off window-unit air
conditioners when spraying is taking place in the immediate area. (you
may open windows and activate AC units 15-20 minutes after the
application, or longer at your discretion)
- Do not let children play near or behind
truck-mounted applicators when they are in use. (pets should be
brought inside if possible or their cages covered to allow a wider
application to be performed)

EPA Fact Sheet, "Pesticides and
Mosquito Control", page 3 - CMMCP

Exclusions
from Spraying
If for any
reason a person wishes their property to be excluded from mosquito spraying, a
registered letter with the names of their property abutters has to be sent to
their local Town Clerk, with a copy sent to our office. The property to be
excluded also has to be marked every 50 feet with signs indicating "No
Spray". Paper plates are recommended for these signs. Any questions
about our program or the exclusion process can be directed to our office at
(508) 393-3055 during business hours. For more information on the exclusion
process, please click here.
