Description

A chlorinated hydrocarbon formerly used as an insecticide, fungicide and wood preservative. First used in 1948, dieldrin was an effective contact insecticide against cockroaches and termites with persistent residual action. However, because of its high chemical stability and high toxicity to birds and fish, dieldrin had drastic long-term environmental effects. It is no longer manufactured or used in the United States and its use is banned in most countries.
