A method to rapidly screen potential bait substrates placed around Coptotermes lacteus mounds is described. A perforated P.V.C. conduit is buried in a shallow trench in a rectangular arrangement around an active mound. Seven P.V.C. holders containing cork baits are inserted vertically into the conduit around the mound. Within three weeks following installation of the baits around five mound colonies of Coptotermes lacteus, all the cork baits were uniformly attacked and eaten. The potential of this test arrangement around termite mounds for assessing the efficacy of wood preservatives and termiticides is briefly discussed.
