What are they?

Carbamates were originally extracted from the calabar bean, which grows in West Africa. Current carbamate insecticides are synthetically manufactured derivatives of carbamic acid.

How do they work?

Bendiocarb and methomyl are both broad spectrum insecticides that kill flies either by contact or ingestion. These products are mostly used as baits to quickly reduce fly numbers in areas people are working.

Carbamates are very similar to organophosphate insecticides in their mode of action by inhibiting acetylcholinesterase, a neurotransmission enzyme, producing neurotoxic effects in insects.
