product name of a mosquito
adulticide used by the Project in
ULV (Ultra Low Volume) sprayers is
called AnvilŪ 10+10. 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
pyrethrums, 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.
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
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
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
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
to avoid exposure. (please notify CMMCP to be placed on the "No
Spray" list -

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
when they are in use. (pets should
be brought inside if possible
or their cages covered to
allow a wider application to be performed)
