A jar of Gnat Heads at Slug & Jiggers Apothecary

Gnat Heads are the cephalic parts of gnats, a species of tiny flying insects in the family of the mosquito.[1]

Gnat Heads, or at least some sort of extract, is sold at Slug & Jiggers Apothecary, in Diagon Alley.[2] For this reason, they are most likely used in Potion-making.
