The Bat-Bogey Hex is one of the more memorable original spells in the books, made famous primarily by a single caster: Ginny Weasley. There is no canonical incantation recorded — the hex appears in the books by description rather than by spoken word, suggesting it may be cast non-verbally as a matter of course, or that the caster's intent and wand movement are doing most of the work. What is canon is the effect, which is exactly what the name announces: the target's nasal mucus transforms into small, vicious, winged creatures resembling bats, and those creatures swarm immediately out of the nose to attack the victim's face.
Ginny Weasley's reputation as the Hogwarts Bat-Bogey specialist is established early. Fred and George Weasley reference it admiringly in the books — calling Ginny's Bat-Bogey "truly impressive" — and Slughorn invites Ginny into the Slug Club partly on the strength of having seen her cast it on a corridor opponent earlier in the same day. The hex is part of why Slughorn finds her so interesting, and part of why Harry, deep into Half-Blood Prince, suddenly notices Ginny is more formidable than he had previously been registering.
The hex's most public on-page cast comes during the Battle of the Department of Mysteries, where Ginny brings down a Death Eater with a textbook Bat-Bogey in mid-fight. The Death Eater drops, swatting at the bats erupting out of his face, and the scene captures something funny and unsettling at once: an obviously gross hex that is also, in the right hands, a genuinely effective combat tool. Most Bat-Bogey'd victims are too distracted clawing at their own faces to keep dueling.
Treatment is straightforward but unpleasant — the bat-creatures dissipate on their own after a few minutes, and any residual discomfort can be cleared up with standard Hospital Wing care. The hex itself is generally classified as a moderate-severity Hex rather than a Curse: not Dark Magic, but firmly on the unpleasant end of the curriculum, and not the kind of cast you make casually.

Bat-Bogey Hex FAQ
What is the incantation for the Bat-Bogey Hex?+
The books don't give one. The hex appears by description rather than spoken word in every on-page cast, suggesting it is generally performed non-verbally — or that the wand movement and intent carry most of the weight. Ginny Weasley is, in any case, well past needing to speak it aloud.
Who is the Bat-Bogey Hex's most famous caster?+
Ginny Weasley. Her brothers Fred and George explicitly call her version "truly impressive," Slughorn invites her into the Slug Club partly on its strength, and her on-page casts in Order of the Phoenix and Half-Blood Prince establish her as the definitive specialist.
How long do the bat-creatures last?+
A few minutes, typically. The creatures dissipate on their own once the cast wears off, leaving the victim with no lasting injury beyond any scratches received during the swarm. Hospital Wing care can clear up residual discomfort.
Is the Bat-Bogey Hex considered Dark Magic?+
No — it's classified as a Hex, not a Curse, and produces no permanent damage. It is, however, firmly on the unpleasant end of the curriculum, and most adult witches and wizards consider casting it on someone without serious provocation worse than the formal classification implies.
