Carpenter ants are one of the most frustrating pests in the Florida Keys. Because of our tropical climate, they can quickly establish large colonies inside homes, decks, and wooden structures. Williams Pest Control has developed treatment methods specifically for the unique challenges of the Keys, helping homeowners eliminate carpenter ant infestations when other treatments have failed.
