Oh, yes, we use one of those around the perimeter of our property (because the road dept gets testy if you ask them not to spray, but then don't control your own weeds). You do have to be careful if there's anything flammable nearby, and they work best if you attack the weeds while they're still small. Less chance of having those charred spots if you do it when they're little. We used ours to attack the out-of-control weeds in our kennel area and managed to set fire to one of the wooden planters on the other side of the fence! Oops!
