Has anyone modified these things to give them a little more power? I have a "gen 1" Bug-a-Salt and it doesn't have enough grunt to kill a fly. I suspect that a stronger spring would do the trick, but haven't seen any tear-downs or mods online. I have seen "bug killer" add-ons for air-powered pellet guns, but they seem kind of iffy for indoor use. [edit: grammar and spelling]
