Ant killer recipe: Borax and sweet (sugar, jam, jelly, etc) placed in a lid. Not kid safe. I poke holes around the top of a plastic cup, like an old yogurt cup, and put the recipe on the lid. Put the yogurt cup with the holes on upside down. The holes let in the ants, but the cup keeps the dog and the kids out. You can use cotton balls like this page calls for too.
