This slots fairly well with my mini-thread on senses for the Turned and other entities, as well as how they would mechanically work and be manipulable.
I think, however, that rather than some sort of throwable chemical which might not make 100% sense, an average Joe survivor could instead opt to use raw flesh (presumably from an animal) as bait instead. As opposed to an offensive application like as a throwable weapon, this would serve more as a distraction in the conventional sense (though it’d also work wonders for getting the Turned in the area to converge on an enemy’s location, or simply to mow them all down).
