Abstract: The invention provides a method and apparatus for controlling termites. The invention provides a tamper resistant bait station, which uses a cellulose bait impregnated with a slow acting toxicant and readily allows entry of termite.

Abstract: The invention provides a method and apparatus for detecting and controlling termites. The invention uses a tubular body with a triangular cross section to hold a cellulose bait impregnated with a slow acting toxicant. The tubular body is placed partly in the ground so that the length of the tubular body is along the surface of the ground. The top of the tubular body is transparent so that one can easily view the bait through the top of the tubular body.

Abstract: The invention provides a method and apparatus dispensing a liquid bait in a refillable manner. The invention provides a transparent bait station in which is mounted to a structure. A liquid bait is injected into the bait station to initially fill and then refill the bait station. The bait is a slow acting toxicant and attractant. The bait station is formed to allow access by bugs, but not by larger animals. The bait station is also able to protect the bait from wind and rain. The bait station prevents leakage of the toxicant if the bait station is tumbled or placed in an incorrect position. The bait station is able to hold two different liquid baits, which may be two different poisons, or a poison and an attractant. An embodiment of the bait station provides a series of inner walls to minimize the leakage of liquid bait, if the liquid bait station is tumbled.

Abstract: This invention describes a method for preparing benzyluracils using methyl benzylcarbamates as intermediates. The method comprises the steps of contacting an alkali metal salt of an ester of 3-amino-4,4,4-trifluoro-2-butenoic acid with a methyl benzylcarbamate I to provide a benzyluracil II. ##STR1## where R, W, V, X and Y are as described in the specification.
