Traps or pots where originally make of wood, typically oak. Wire mesh traps have replaced the wooden traps for the most part. Lobster enter through the net “head” to go after the bait in a bait bag placed in the “kitchen”. When it tries to exit it lands in the “bedroom” or “parlor”. Some traps have more than one kitchen and bedroom. Traps are required to have an escape vent that is large enough to letter all but the legal size lobsters escape. Traps also are equipped with runners that help prevent legs, claws and antennae from being pinched between the bottom of the trap and the boat when the traps are hauled.
