  • Patent number: 6681518
    Abstract: An insect lure or bait container for attracting insects for treatment with a pesticide has an opening therein for the subterranean ingress and egress of insects and, preferably, contains a cellulose fiber lure of a coherent deformable compressible mass of randomly oriented, entangled, softwood fibers that is held together by entanglement of the fibers. Preferably, for treating termite colonies, the pesticide is a non-repellent termiticide, which is lethal to termites through matrix contact as well as through ingestion and/or transferal.
    Type: Grant

  • Patent number: 6584728
    Abstract: A termite colony is treated with a termiticide by locating a bait station on or beneath ground surface, adjacent a building, to attract termites in the region. The bait station container holds nontoxic cellulose bait. An opening in the bottom permits termites' ingress and egress to feed on the bait within the container. An opening in the top permits termite activity within the container to be monitored without disturbing the bait within the container and permits a termiticide to be introduced directly into the soil and termite tunnel tubes beneath the container by passing a termiticide injection tube through the openings in the container and into the soil beneath the container. Preferably, the termiticide is a non-repellent termiticide, which is lethal to termites through ingestion, contact and/or transferal.

  • Patent number: 6493987
    Abstract: A pesticide delivery system includes a service box and a plurality of tubular delivery and dispensing lines for carrying a pesticide from the service box to locations in a building structure and dispensing the pesticide in those locations to control and exterminate pests. The service box includes a plate with holes through which elastic end portions of the tubular delivery and dispensing lines pass. Each of the holes has a conical frustum shaped portion and an annular edge portion that has the smallest diameter of the hole and is less in diameter than an outside diameter, in an unstressed or unstretched state, of the elastic end portion of the tubular delivery and dispensing line passing through the hole whereby the annular edge portion of the hole grips and locks the tubular delivery and dispensing line in place.

  • Publication number: 20020116866
    Abstract: A termite colony is treated with a termiticide by locating a bait station on or beneath ground surface, adjacent a building, to attract termites in the region. The bait station container holds nontoxic cellulose bait and has openings in a bottom wall and an upper wall. The opening in the bottom wall permits termites' ingress and egress to feed on the nontoxic bait within the container. The opening in the upper wall permits any termite activity within the container to be monitored without disturbing the nontoxic cellulose bait within the container and permits a termiticide to be introduced directly into the soil beneath and one or more termite tunnel tubes, beneath the container and leading into the container through the opening in the bottom wall, by passing a termiticide injection tube through the openings in the upper and bottom walls and into the soil beneath the container. Preferably, the termiticide is a non-repellent termiticide, which is lethal to termites through ingestion, contact and/or transferal.

  • Patent number: 4893434
    Abstract: A gas or liquid distribution system in a building for pest control in the building has a plurality of flexible tubes in the walls of the building. Each tube has a plurality of openings unevenly spaced along the side thereof along one end portion of the tube. Each tube passes through a predetermined zone in the building and has a portion without any openings extending back to a control distribution box attached to the side of the building. A panel inside the control distribution box has a plurality of openings passing therethrough and has the open end of each flexible tube attached through an opening in the panel using a special pipe end connector for connecting the tube to the panel. The pipe end connectors are color coded to indicate the amount of pesticide liquid needed to be distributed to the building zone for the particular tube. In addition, the panel has a coding system to indicate which pipe inlet is for which building zone.
