  • Patent number: 4807392
    Abstract: A threshold poison bait station having an opening or openings in a threshold frame that are narrow in width and short in length. "V" shaped directing guides are connected to the openings thereby preventing direct, straight line access from interior openings to exterior openings and also thereby creating an enclosed insect access channel which directs insects along the channel to an interior poison bait receiving station. By extending one of the "V" shaped directing guides in length, a deep, dark, interior poison bait receiving station, which is very attractive to insects, is provided. While the device may be "armed" with the poison bait of the user's choice, little fear of contact with the poison bait by children or pets arises because the openings are so small yet so attractive to insects. In another form, a permanent division is placed dividing the threshold poison bait station in two and preventing access from the interior to the exterior, or vice versa, by insects.
