I know what you mean about the sand build up, it's not even dirt anymore. We have tired just about everthing there is, and to be honest with you, if you keep at them all day long, every day, going with the cheap stuff works as well as the more expensive stuff as Ortho. Right now I have a large can of some generic spray for ants/roahes, and I poke a stick in the mound to get them going, and just spray like crazy. They move within a few hrs, what's left of them, and I repeat. Right now they are under my son's portable basketball hoop..the mound has to be at least 6 inches high, all around the base. I haven't gotten to it yet this wknd, hoping they think I have forgotten! lol

I heard that you can take a shovel of them from a mound and throw it on another and they'll attack each other as rivals,even going after the queen.
