Fluoroacetamide, a similar pesticide, is known as Compound 1081. These compounds are widely effective as poisons against most mammals and some amphibians.26 Both products were banned in the United States in 1972, except to protect sheep and cattle from coyotes. Collars embedded with SMFA are placed around the neck of livestock, the typical point of attack for coyotes.
