We show a theorem proving that a non-local bosonic field upon a covariant interaction with a confining gauge field undergoes the confinement of its degrees of freedom present in the free theory changing completely the physical mass spectrum. This is applicable to an infinite number of excitations of the bosonic field including ghosts whereas we pay special attention the the modes with the complex conjugate masses – mysterious states appearing in the string field theory motivated infinite-derivative models. The same recipe will obviously work for the Lee-Wick models.
