Abstract: In this note we discuss the effect of the $ \textrm{B}\mathbb{Z}/p$-nullification $ \mathbf{P}_{\textrm{B}\mathbb{Z}/p}$ and the $ \textrm{B}\mathbb{Z}/p$-cellularization $ \mathbf{CW}_{\textrm{B}\mathbb{Z}/p}$ over classifying spaces of finite groups, and we relate them with the corresponding functors with respect to Moore spaces that have been intensively studied in the last years. We describe $ \mathbf{P}_{\textrm{B}\mathbb{Z}/p}\textrm{B}G$ by means of a covering fibration, and we classify all finite groups $ G$ for which $ \textrm{B}G$ is $ \textrm{B}\mathbb{Z}/p$-cellular. We also carefully study the analogous functors in the category of groups, and their relationship with the fundamental groups of $ \mathbf{P}_{\textrm{B}\mathbb{Z}/p}\textrm{B}G$ and $ \mathbf{CW}_{\textrm{B}\mathbb{Z}/p}\textrm{B}G.$
