🧪 Treatment Plan
Little Black Ants respond well to both sweet gel baits and exterior perimeter sprays. Focus bait placement on active indoor trails and exterior nesting sites.
Apply pea-sized drops of sweet gel bait along active indoor trails, in cabinet corners, and near entry points. Terro Liquid Ant Bait is the go-to product — worker ants carry the borax-based bait back to the colony, eliminating it over several days.
Prevention After Treatment
