Same here for the hills sprouting in the driveway. It is a never-ending battle.Those ant's are always out thick after the rain. That's the best time to find the hill's though, as they are trying to re-build them, then they start gathering new food for it. They have to feed the queen and all of those little hatchling's from the queen. That's why I'm out there after the rain's with my Permethrin 10 solution.
