ants!

So, my Nosh & Nurture readers, today I came home to ANTS. It's summer and they've made their way into my kitchen seeking water and food I'm sure. We've located the little mound out in our yard, but Mr. Charming's instinct was to grab the ant spray for in our home! Since we are in the process of ELIMINATING all chemicals and toxins from our environment I'm thinking ant POISON is the LAST thing I want in my home, especially in my kitchen. So for the time being we sprayed our vinegar counter cleaner on them while we research natural ways to eliminate them and detour them from entering out home. Are there any natural remedies YOU'VE used on these little picnic-y pests? Leave advice in the comment box in the right hand column! Any advice would be appreciated. When we find a good solution, I will post it here as well.
