Heptachlor is an insecticide that usually comes in the form of a white or tan powder, the tan powder being of lower purity. It is similar to insecticide chlordane. Heptachlor was widely used in the past to kill insects. In 1962, Rachel Carson's "Silent Spring" questioned the safety of heptachlor. The Environmental Protection Agency has banned the sale of heptachlor products in the United States and limited use to the specific application of fire ant control in underground transformers. Due to its highly stable structure, heptachlor can persist in the environment for decades. The amount that can be present in different foods is regulated.
