  • Patent number: 11013225
    Abstract: An intercepting device (e.g. a furniture coaster device) is placed under furniture (bed, sofa, chair. etc.), other climbable 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.

  • Patent number: 9510581
    Abstract: Various embodiments of the present invention provide a lure composition, lure arrangement, and/or method for attracting and capturing bed bugs and the like. In some embodiments, the present invention combines a collection structure with a chemical lure composition that has improved efficacy due to a synergistic combination of elements. The present invention reduces the need for sprayed or broadcast attractants. In one aspect of the invention, a lure composition for attracting bed bugs and the like is provided. The 5-chemical lure mixture comprises a combination of Nonanal, 1-octen-3-ol, L-lactic acid, spearmint oil, and coriander Egyptian oil. In another embodiment of the invention, the mixture comprises a 4-chemical lure mixture Nonanal, 1-octen-3-ol, spearmint oil, and coriander Egyptian oil.

  • Patent number: 9066511
    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.

  • Publication number: 20140250766
    Abstract: An insect trap has a ā€œUā€ or similar shaped cross-section view, forming a circle or square, with a dark-colored coarse outer surface and a light-colored smooth inner surface. The trap can be placed around an arthropod-infested object such as furniture leg, luggage, food to form a barrier to prevent movement of arthropods between the infested object and its surrounding areas. The trap can also be placed where arthropods live or forage to monitor their numbers and activities such as at corners of a room, along perimeters of a room, inside a cabinet, inside food storage container, etc.

  • Patent number: 7583040
    Abstract: An operating device for an overhead closure which comprises a motor, operatively connected to the closure for opening and closing the closure, and at least one sensor unit mountable either the closure or a support surface bordering the closure. The sensor unit is operable to detect the presence of an obstacle obstructing a travel path of the closure and to generate a signal in response thereto. A control system is in communication with the sensor and with the motor. The control system includes a control unit which receives the signal and provides a sensing feature which stops and/or opens the closure in response to the signal. The control unit deactivates the sensing feature at a selected point prior to an end limit position of the closure. The selected point is determined by the control unit based on a calculated delay characteristic.
