A first embodiment fills a chamber with a food and places it adjacent to an arthropod population such as termites, so that live termites can then enter the entrance/exit of the tube to reach the food. Once termites are inside the tube, a non-edible foraging matrix, such as a disc of loose soil, sand, rocks, shale, and gravel that is treated with a slow acting and non-repellant toxicant, is placed between the food in the chamber and the termite entrance/exit. Termites are forced to pass through and disperse the slow-acting and non-repellent toxicant through their tunnels and living space in order to kill termites over time.

  • Publication number: 20020189491
    Abstract: The invention relates to the impregnation of wood by a solvent-free melt of modified natural resin which is solid at ambient temperature. Besides the modified natural resin, melts according to the invention may comprise wax and further additives. The melting point of the wax is preferably above 80° C. The addition of wax elevates the softening point and reduces the viscosity of the melt. Melts according to the invention do not tend to discolor even at the given temperatures of the loading treatment so that the wood treated with a melt of modified natural resin mainly retains its natural appearance.
