Go to feed store - get some liquid fly attractant. Only need an ounce to put in a gallon. So fucking nasty - probably made of all the suggestions above.After a chat with some other like-minded assholes on discord, we've decided that a champagne bottle is best because you can safely pressurize those to "shit's gonna go everywhere" pressure. Throw in some soap too so it foams everywhere.
The big question is what to throw in there for the smell. Deer piss? fish sauce? dollar store perfume? some kind of hippie essential oil bullshit?
They don't know who did it.Hunters skunk scent, etc.
Also it sounds like they know who did it, in which case bringing the fucker within an inch of their life, or at least making them believe that's where they are, is far better than some freshman level stinky champagne.
Also it's assumed that the thieves are renting their home, so doing anything that'd permanently stink out the house would probably just fuck over their landlord.
