I live in Columbus Ohio and have a black ant colony right on the side of my house. I have researched and am going to use the Boric Acid or boiling water approach. Since I know where the colony/nest is should I first pour gallons of the boiling water then bait with the (1C Water / 2C Sugar / 2Tbs Boric Acid) mixture? Or should I just pour the Boric Acid mixture on the nest? Also, can I just use Borax since I already have it in my home? If so is it the same quantity as noted above?
