The non-rotating fermion vacuum in Kerr spacetimes is unstable to a spontaneous vacuum decay, which leads to the formation of a co-rotating Dirac sea. This decay, which amounts to the fermionic pendant of the black hole bomb instability, has an analogue in the electrodynamics of supercritical fields, and we show that the decay process is encoded by the set of quasi-normal fermion modes.
