Just after 10:00 Wednesday night, authorities were called to a home on Main Road in Milford.
The man inside the home says he caught people trying to steal his plants.
According to police, the resident then shot at the suspects repeatedly, causing them to flee into the woods.
Authorities were unable to locate the two suspects, but say there is no indication that either of them were hit by gunfire.
Anyone with information about this incident is asked to contact the Penobscot County Sheriff's Office at 945-4636.
