The Bug-A-Salt 3.0 has the feel and appear of a Nerf gun, but it surely shoots a small burst of desk salt that, theoretically, will kill a fly. It’s actually entertaining to make use of, but it surely’s not very sensible and, actually, not all that efficient. There have been instances once we may kill a fly in a single shot, but it surely usually took two and typically three pictures. Hornets and wasps sometimes took 5 or 6 pictures to kill. The Bug-A-Salt can be for out of doors use solely—we examined it indoors and salt simply finally ends up in all places. It’s good for amusing or for sitting on a deck and selecting off any flies that land on the railing, however past that, we’ll move.
