There will always be ongoing problems with chemical barriers, natural barriers and most of all, Pre Construction. Home owners are not schooled in the way of subterranean termites and therefore will generally create a void in the barrier by toiling the soil or planting a shrub or allowing a broken down-pipe to go unfixed resulting in its water leaching the chemical out of the soil.

The majority of attacks by the subterranean termite coptotermes SPP can often be attributed to pooling of moisture against the house footings behind down-pipes. American pest controllers have been using boron based products successfully for many years. This is new to Australia and is being met with a lot of resistance from the uninitiated and the uninformed. New Zealand has for many years adopted the use of boron treated timber as a pre-requisite to building. This treatment became optional and not mandatory some 15 years ago, and the result was a huge disaster for the non treated house. The main concern was wood rot and borer in epidemic proportions.
