After the Ghostbusters defeated the Vase Ghosts, Ray Stantz comes in from upstairs and shuts the door behind him. When Peter Venkman opens the door he sees tons of Possessed Cockroaches coming down the stairs. After completing the bust and returning to the Firehouse, Peter gives an antenna to Janine Melnitz. Also, the Ghostbusters are seen carrying two traps when they go down to the Containment Unit. Since one trap was used to capture the Vase Ghosts, it is likely that the other trap was used to capture the Possessed Cockroaches.
