Argentine Ants in Kitchen: Identify, Bait, Seal—Don't Spray

First, confirm species (honey on card, follow trail). Don't spray—it scatters colonies. Puff boric acid into entry, caulk. Wipe scent trails. Eliminate food sources. Use slow-acting baits (Maxforce, Combat, Terro) where ants forage. Check monthly. Perimeter spray with bifenthrin/etc. as backup. ID resources: Ohio State, Auburn.
