When Ghostbusters NJ personnel know ghosts won’t be escaping, its time to get them into the trap. How is this done?
When a trap is set, Ghostbusters NJ personnel can lower their particle throwers, bringing the ghosts towards the trap. Once the doors are open, a coned beam of light will shoot out from the trap. Within the light is actually a kind of energy which pulls the ghosts into the trap. At this point, Ghostbusters NJ personnel have stopped firing the proton beams at the ghosts. This is because its too late for any ghost to escape.
Ghosts can only be released from the traps by emptying the traps into the Ecto Containment Unit.
