I use this as well! It's not too expensive and there are NO bugs. Seems to last quite a while too. It will kill bee's also, so if you do use it be mindful of plants that you spray around the house.
I ended up grabbing a bag of this stuff since I was at Lowe's and they didn't have the other product from Tractor Supply. I sprinkled is all around the Holz Hausen, and all over the wood...then watered it all in. There was still a bit of munching going on about an hour later, but I'm hoping it's gone within the next couple of days.
That stuff should get them, I pour it on little ant hills I find around the yard too, couple days and I don't see any more ants
