A bed bug trap includes heat, carbon dioxide and/or semiochemicals (pheromones and/or kairomones), to attract and trap bed bugs. The trap may be combined with the appearance and/or function of another appliance, such as an air freshener. The release of semiochemicals may be combined with the release of air freshening compositions. The device preferably is powered, but not necessarily. The bed bug trap may provide one attraction mode, or two attraction modes, namely one which uses heat, carbon dioxide and/or kairomones to attact bed bugs seeking a meal, and the other which uses pheromones to attract bed bugs seeking a safe harbor, i.e. a hiding place. The two different modes may operating simultaneously in different areas, or the trap may be switchable between modes, for example via a timer, or in response to some trigger such as a light sensor. Alternatively, one mode may operate continuously, for example the mode in which bed bugs are attracted to a harboring location, while the other mode, for example the mode in which bed bugs are attracted to a feeding location, may be operated only intermittently. The bed bug trap may be combined with a wide variety of appliances, such as air fresheners, alarm clocks, clock radios, humidifiers, desk or table lamps, power bars, etc.
