The product used by the Project during the early
morning aerosol applications is called Anvil. Anvil is a combination of two
ingredients, Sumithrin and Piperonyl Butoxide. Sumithrin is a synthetic
Pyrethroid, and Piperonyl Butoxide (PPO) is a synergist which enhances the
effectiveness of Sumithrin. PPO, because of this enhancement affect, allows the
Project to control the adult mosquito at very low concentrations of Sumithrin.
Anvil is applied from the truck (ULV
Truck picture) at a vehicle speed of 10 miles per hour. Due to the
extremely low dosages of the active ingredients these applications are often
referred to as Ultra Low Volume or ULV applications. These treatments represent
a minimal risk to humans, pets and non-target species because of the low dosage
and because the Project conducts these applications early in the morning
between the hours of
The Project conducts these early morning
applications from approximately Memorial Day to Labor Day and some times
further into the fall. Weather and mosquito populations as well as mosquito
born disease transmission threat determine the actual beginning and end of our
ULV program. The time of day the applications take place is between
The application equipment is mounted in the back
of a ½ ton dark blue pickup truck. The applicator drives the vehicle down each
street in the area to be sprayed and can control the spray from inside the
vehicle via an on/off toggle switch, without needing to shut down the
application equipment engine. These applications are based on public requests
and/or field surveillance and/or mosquito born disease threat.
If for any reason a person wishes their property
to be excluded from these applications, 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". Plastic plates located at eye level
are recommended for these signs. Any questions about our program or the
exclusion process can be directed to our office at
