  We show that a spectral wall, i.e., an obstacle in the dynamics of a bosonic
soliton, which arises due to the transition of a normal mode into the continuum
spectrum, exists after coupling the original bosonic model to fermions. This
spectral wall can be experienced if the boson or fermion field is in an excited
state. Furthermore, while passing through a spectral wall, an incoming
kink-fermion bound state can be separated into purely bosonic kink, which
continues to move to spatial infinity and a fermionic cloud that spreads in the
region before the wall.
