We had a problem with ants when we were camping on Oahu. These were teeny, tiny, itty, bitty ants that were actually crawling in through the mesh in the tent. And boy did they bite! This was our backpacking tent that we frequently use in grizzly country, so there has absolutely never been any food or drink of any kind near it. It was very irritating, but I guess I'll be thankful that at least they didn't eat holes through my tent.
