Coyotes are classified as Predatory wildlife in Idaho. The only firearm restriction for the hunting of Predatory, Furbearers, or Unprotected wildlife is that “no person shall …hunt with any weapon the possession of which is prohibited by state or federal law.” IDAPA 13.01.16.400.02.a. The use of an airgun to hunt coyotes (Predatory wildlife), permissible Furbearers, or Unprotected wildlife is allowed in Idaho.
The administrative rules of the Idaho Fish and Game Commission/Idaho Department of Fish and Game are found at:

Because airguns are not prohibited as a method of take for Predatory, permissible Furbearers, or Unprotected wildlife, the use of an airgun to hunt coyotes is allowed in Idaho.
