Just stayed at Lake Skinner near Temecula, CA. Woke up in the morning and the whole inside of the Mother Ship was crawling with ants. DW was totally freaked. She wants a professional exterminator...
We've used Terro for years. Little bait trays that you set out and the ants are gone in a day or two. We set them where we find the ants "running" as a column. They love the stuff, my wife says it looks like an old drive-in with them all around chowing down. After eating they take the bait back to the colony and more come to dine, eventually they disappear along with the colony. Works best with "sweet" ants. You can find it at Walmart, Target, Lowes, Home Depot and most hardware stores.
