That stuff really works. I had a run-in with the little critters a couple of years ago. One application with a fogger and the problem was solved. 100% non-toxic to pets and humans, but if you spray a small amount on a bedbug it is dead literally in one second. The only ingredients are cedar oil and hydrated silica (the main ingredient in toothpaste).
it was used in Kuwait. Iraq, and Afghanistan by our soldiers too
