Hi Kim,
We had an ant problem outside and I talked to a friend of mine that grew up on a ranch. We had been using some of the harsh chemicals as well and it wasn't working as well as we'd hoped. Anyway, my friend told me to buy a large bottle of generic cinnamon from the store and sprinkle some wherever you see them. I'm not kidding by the next day they were completely gone and I haven't seen them since! I eventually cleaned up the cinnamon after a few days and haven't seen them all summer. I hope this helps and good luck.
