Patent number: 5927001Abstract: 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.Type: GrantFiled: February 3, 1997Date of Patent: July 27, 1999Assignee: FMC CorporationInventors: James Bruce Ballard, Elleen Patricia Mc Gorman
