Important differences in termite control in South-East Asia and the use of non-repellent termiticides under such conditions

Abstract:
Termite control practices in South-East Asia differ in some important respects to those typically undertaken in USA, Japan and Australia. Whilst the basic principles are similar, differences in construction practices, type of building, termite species, and environmental conditions each contribute to the necessity to modify the termite control solution. Higher density housing is also common in South-East Asia with large numbers of multi-storey apartment complexes, and terrace-type (linked) houses requiring protection. In such situations it is common for termites to gain access from an adjoining structure rather than from the soil. Another important feature of buildings is that they have a concrete-apron and drain surrounding the external perimeter of the building. The most common and damaging termite species are Coptotermes sp. In addition, buildings can be infested with Nasutitermes sp., Macrotermes sp., and Microcerotermes sp., amongst others. The environmental conditions are favourable to termite activity all year round. This means it is typical for termites to infest buildings within three years of being built. Termite control in South-East Asia represents a great challenge. It is critical that a thorough termite inspection is conducted prior to treatment to identify all the termite sources and entry points. With the introduction of non-repellent termiticides, a more reliable termiticide solution can be applied to eradicate and protect the structure incorporating both soil and above-ground treatments. Whilst 100% success cannot always be guaranteed, risks can be substantially reduced to very low and acceptable levels.
