The Philippines supports 54 known species of termites encompassing 18 genera. Within these genera, three families are of economic importance and associated with damage to wood products and timber structures, viz, Rhinotermitidae, Termitidae and Kalotermitidae. Four subterranean termite species are considered serious structural pests, viz., Coptotermes vastator Light, Nasutitermes luzonicus Oshima, Macrotermes gilvus Hagen and Microcerotermes losbanosensis. These species are widely distributed and can cause significant structural damages. Current methods to control these wood-boring insects ranged from chemical barrier to termite baits. The present paper discusses the benefits of termite baiting vis-a-vis the conventional chemical barrier treatments. Current research of the author on the search for potential bait toxicant against Philippine subterranean termites showed that thiamethoxam and chlorfluazuron are effective against C. vastator, N. luzonicus, M. gilvus and M. losbanosensis. Foraging populations and territories of these species are also discussed, as well as future trend in control methods against higher species (Termitidae) of subterranean termites.
