Crawling arthropod intercepting device and method
DC CAFCFirst Claim
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.

Abstract
An intercepting device (e.g. a furniture coaster device) is placed under furniture (bed, sofa, chair. etc.), other climable object, or the floor adjacent an object to intercept crawling arthropods and other crawling pests. The intercepting device can be used to monitor the presence of crawling arthropods and other crawling pests (such as bed bugs, ants, cockroaches, beetles, spiders, etc.), reduce pest numbers, and monitor efficacy of pest control procedures. The intercepting device includes pitfall trap surfaces that form multiple pitfall traps.

- 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.
- 7. A method of intercepting bed bugs between a climbable upstanding surface of 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 climbable upstanding surface of a leg of the bed, the upholstered sofa, or the upholstered chair with the climbable upstanding surface of the leg having a lower end received on a bottom wall of an inner receptacle of the intercepting device to provide a path for bed bugs departing from the bed, upholstered sofa, or upholstered chair to enter the inner receptacle and with an underside of the bottom wall resting directly on the floor, wherein the inner receptacle is formed by an upstanding peripheral surface that is slippery to prevent bed bugs from climbing out of the inner receptacle such that the inner receptacle forms a first inner pitfall trap free of liquid around said leg and surrounding the inner receptacle by a second outer receptacle of the intercepting device wherein the outer receptacle is formed between an upstanding inner peripheral surface that is connected to the perpriperal surface of the inner receptacle and an upstanding outer peripheral surface and wherein the inner peripheral surface and the outer peripheral surface of the outer receptacle are slippery to prevent bed bugs in the outer receptacle from climbing out such that the outer receptacle forms a second outer pitfall trap free of liquid, said outer receptacle being accessed by bed bugs approaching the intercepting device by an upstanding, exterior bed bug-climbable surface that is connected to the outer peripheral surface of the outer receptacle, wherein the upstanding peripheral surface of the inner receptacle and the upstanding inner peripheral surface of the outer receptacle ascend to a common peripheral rim that is in such non-overlying relation to the inner receptacle and the outer receptacle that the rim does not impede viewing of the inner receptacle and the outer receptacle from above, and using a human on the bed, the upholstered sofa, or the upholstered chair as bed bug bait in capturing bed bugs in the inner receptacle, the outer receptacle, or both as a result of the bed bugs being unable to climb out, including capturing any bed bugs departing from the bed, the upholstered sofa, or the upholstered chair in said inner receptacle that forms said first inner pitfall trap and capturing any bed bugs approaching the bed, the upholstered sofa, or the upholstered chair in said second outer receptacle that forms said second 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 from the floor, or both, by viewing the intercepting device from above.
