This is the nuclear option in a tiny jar. Mix equal parts sugar and borax laundry booster. Add a little warm water to make a paste. Ants love sugar more than a toddler loves candy. They carry it home to feed the queen.
Borax messes up their stomach enzymes. They die slowly, but they share the poison with the whole colony. It’s like sending a poisoned pizza to the enemy headquarters. Diabolical? Maybe. Effective? Absolutely.
Test it with a dab on a piece of cardboard. Place it near the trail. Do not put it where pets or kids can reach. Borax is no joke for mammals. Keep it safe.

Do Ants Eat Grass? + How To Remove Them Effectively
Sprinkle a thin line of DE around the foundation of your house. It works best when dry. If it rains, reapply. It looks like flour, but it’s razor blades for insects. Use food-grade DE only. The pool filter kind is dangerous to breathe.
