2 parts Honey to 1 part yeast. Long time ago someone told me to warm some honey to disolve a some yeast. The honey attracts the ants, they take it back to the nest. The yeast swells up and bam their gone. I heard they actually take it to the queen and feed her, so this may get rid of the whole nest. I placed this mixture in a shallow dish, covered, so other animals can’t get to it. They were all gone within a day.
