Can I use a silencer

Can I use a silencer and my hunting rifles while big game hunting in Idaho?
Answer: 
Idaho Fish and Game does not prohibit the use of silencers.  However, ATF (Alcohol, Tobacco, and Firearms) requires a permit to possess and use a silencer.  I recommend you contact the local ATF office for the appropriate applications.
