There are several interesting sidelights when you consider TERM's termite barrier system.
The first is that termites are of considerable ecological importance. They mostly feed on dead plant material and cellulose (usually in the form of wood), as well as leaf litter, soil, and dung, termites are major detritivores. This means that termites contribute to decomposition and the nutrient cycle.
Of course, if termites are decomposing wood inside our structures, they are doing ecological damage. So it is best to keep them outside of the structure and cause them to go someplace else.
Termiticides are unsustainable in several ways. They pollute the environment, disrupt the cycle of nature, hurt people, and reduce the quality of living inside the structure.
Another sustainability consideration has been pointed out by Dr. John Wargo, Professor of Environmental Policy, Risk Analysis, and Political Science at the Yale School of Forestry & Environmental Studies. Dr. Wargo, makes a good point about indoor air quality:
