1. A method of intercepting bed bugs between a leg of a bed, an upholstered sofa, or an upholstered chair and a floor, comprising placing a bed bug intercepting device on the floor under the leg of the bed, upholstered sofa, or the upholstered chair with a lower end of the leg received on a bottom wall of an inner most receptacle to provide a path for bed bugs departing from the bed, upholstered sofa, or upholstered chair to enter the innermost receptacle, wherein the innermost receptacle is formed by an upstanding peripheral surface that is slippery to prevent bed bugs from climbing out of the innermost receptacle, wherein the innermost receptacle provides a liquid-free inner pitfall trap of the intercepting device and with an underside of the bottom wall resting directly on the floor, and surrounding the inner pitfall trap by a second liquid-free outer pitfall trap formed by multiple upstanding pitfall trap surfaces disposed between the inner pitfall trap and an upstanding, exterior bed bug-climbable surface of the intercepting device, the second outer pitfall trap comprising an upwardly directed receptacle open at a top thereof, and using a human on the bed, the upholstered sofa, or the upholstered chair as a bed bug bait in capturing bed bugs in one of more of the inner or outer pitfall traps as a result of the upstanding peripheral surface and the pitfall trap surfaces being slippery so that bed bugs cannot climb the upstanding peripheral surface and the pitfall trap surfaces, including capturing any bed bugs departing from the bed, the upholstered sofa, or the upholstered chair in the inner pitfall trap and capturing any bed bugs approaching the bed, the upholstered sofa, or the upholstered chair, from the floor in the outer pitfall trap, whereby an individual can determine whether bed bugs are departing from the bed, upholstered sofa or upholstered chair, or approaching the bed, upholstered sofa or upholstered chair, or both, by visual inspection of the intercepting device.
