Alana Annette Savell, 32, was hosting a couple at her Panama City home when the visitors apparently became noisy.
Police say she ordered them to go, before shooting the man and woman in the legs. The victims went to hospital with non life-threatening injuries.
Ms Savell has been charged with aggravated battery by a firearm.
Bay County Sheriff’s Office told the BBC the female victim had turned up with a male friend, whom she had just met in a bar, at the accused’s home at around 01:00 local time on Monday.
