Anvil (insecticide) (original) (raw)

Anvil is an insecticide widely employed to combat West Nile fever, a mosquito-borne disease identified in approximately 10,000 residents of the United States from 1999-2006. It is sprayed in Chicago and many other cities. Sumithrin, a synthetic pyrethroid, is the main active ingredient. The active ingredients in Anvil break down quickly in sunlight and do not bioaccumulate. There are no reentry precautions for Anvil. Anvil has been tested in 43 field trials in the United States against 30 mosquito species.
