Lorenzo Maggiore is using fundraising site IndieGoGo to get his fly-killing shotgun, “BugASalt” on the market, the Daily Mail reported.
The water-pistol-like weapon uses just salt, and is harmless against people.
But for flies, the attack is deadly, the paper said.
Maggiore originally asked for $15,000 to bring his creation to life, but fans on the website have so far raised $62,000, with 45 days left before the fundraising drive ends.
Pre-orders for the gun start at $30 and you can get them here.
