The bed bug trap has a base, and a lid sealable against the base but leaving a gap in at least a portion around the periphery between the base and the lid. The base has a recess therein containing a glue pad, preferably on a removable and replaceable tray. The outer portion of the base is sufficiently textured for a bed bug to be able to climb into and enter the trap through the gap. A carbon dioxide generator is connectable to the trap. A heat pad may be clipped to the trap. A travel kit includes the bed bug trap and other items which may include the carbon dioxide generator, the heat pack, and other accessories.
