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 definitely entertaining to make use of, but it surely’s not very sensible and, truthfully, not all that efficient. There have been instances once we may kill a fly in a single shot, but it surely typically took two and generally three pictures. Hornets and wasps usually took 5 – 6 pictures to kill. The Bug-A-Salt can be for outside use solely—we examined it indoors and salt simply finally ends up all over the place. 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 cross.
