About Anvil® 10+10:
The product name of a mosquito adulticide used by the Project in ULV (Ultra Low Volume) sprayers is called Anvil® 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.
Some common pyrethroid products use by consumers include pesticides for common household pests such as ants and wasps; flea and tick shampoos/collars for pets; lice and scabies treatments (shampoos, etc.) for humans; insect repellent clothing, etc.
Adulticiding with Anvil®:
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.

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.
- 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).
Beginning August 6, 2001, all tentative spray areas received by citizen's request scheduled for that evening will be listed on the CMMCP phone system after 3:30pm. Please call (508) 393-3055 to access this information.
