Termite Management and the U.S. Experience: A Case for Wood Treatment & Integrated Control

IRG/WP 15-30678

J D Lloyd, K van den Meiracker

A brief overview of termite control is given using specific experiences from the U.S.A. Five major types of termite treatment now prevail: soil applied chemical barriers, in-structure chemical barriers (in-situ applied wood and foundation treatments), physical barriers, treated wood and termite baits. In general, ‘stand-alone’ pretreatments or ‘primary’ treatments are often discussed and even required, although in actuality control typically relies on a number of interacting factors. The different termite control systems are discussed as well as some important building code and construction aspects which can help or hinder long-term protection against termites. The control strategies in current use are explained and performance of primary control strategies for various pests and construction types, and possible supplemental treatments are suggested. It was found that no single treatment can perform in all areas and on all construction types and a summary table developed should help specifiers select appropriate protection.
