Hi Kelly,
We live in the same neck of the woods and I find that something called Grant's Ants traps work great. I get them at Orchard. They are spikey things you are supposed to spike into the ground but I just lay them down inside and in a few hours the problem is gone. I had them in my car too!!! Put in a few Grant's Ants and poof!. They are enclosed and the kids don't seem to bother with them but if they do you can put them out of sight/reach. I also had ants coming up thru the drain and I put some white wine vinegar down the drain and it seemed to do the trick.
Good luck!
Claudia
