Does it really kill them though?
I'm a fan of my electric swatter (because I can catch them in-flight with it) but I have to keep it buzzing for a bit to make sure they're really dead, and then it smells slightly burnt.
It kills. Roaches might take two or three shots depending on their size and your aim, but it kills.
Amazon reviewers claim the 'Bug-A-Salt 2.0 Lawn & Garden Model' works well on palmetto bugs, which I think it just what they call giant roaches in Florida?
I disposed of 63 wasps over a period of about 3 weeks with it. Can confirm that it kills at a range of 6 inches by blowing the body apart. So, usually it was two shots, one to immobilize and another to kill. Vastly prefer this to spraying chemicals around or having a dirty fly swat
hanging around.
