One thing I've done about ants is take a dixie cup and cut it to make a tray about 1/2 dp. Mix three to one with your molasses or honey and boric acid in the cup. Stuffs real cheap and you can probably find it at a hardware store I found mine at a local dollar store, (not THE Dollar Store I mean a cheapass store). The ants will eat it and bring it back to the nest and feed it to the rest, young ones also. Give it about a week or two, bingo ants gone . Diatomaceous, I believe, can also be found at swimming pool stores. It's what's used in the filters.
I do this trick outside around my house. I take another cup and cut "V" grooves around the top edge. Then turn it over to cover the cup to keep the weather out and put a rock on top, big enough to keep it from being blown over but not too big to crush the cup. I place them near spots where I've seen carpenter ants or other insect pests.
