Bundimun

Bundimun is a worldwide house-infesting magical creature whose secretions rot the foundations of the buildings it inhabits. Its account makes domestic space both habitat and point of vulnerability: an infestation may remain concealed beneath floorboards or behind skirting boards until decay announces it with a foul stench.

Habitat and Signs

Bundimuns are found worldwide and are skilled at creeping beneath floorboards and behind skirting boards, where they infest houses. Their presence is usually announced by a foul smell of decay. The sequence gives the creature a distinctive pattern of concealment and revelation: it occupies spaces ordinarily hidden from view, but its infestation becomes perceptible through the air of the home.

Damage and Classification

A Bundimun oozes a secretion that rots away the very foundations of the dwelling in which it is found. Its danger is therefore not limited to an encounter with the creature; the building itself is subject to gradual damage from within. The account begins its entry with the Ministry of Magic classification XXX, placing this information within the book’s system for describing and assessing magical creatures.

Place in Magical-Creature Governance

The Bundimun’s destructive effect on inhabited buildings helps illustrate why magical creatures that intrude into human spaces create practical work for the Department for the Regulation and Control of Magical Creatures. The wider account describes that department as responsible for creatures that remain conspicuous to Muggles, and notes controls on selling and breeding fantastic beasts, including the 1965 Ban on Experimental Breeding. These broader policies establish a framework for managing creatures and their effects; the specific Bundimun entry does not state a separate control, remedy, or method of removal for this species.
