Controlling termites
Building
codes in the United States and other countries are being modified because
of research by Clemson scientists. The researchers found that termites
use foamboard insulation as a superhighway from their underground chambers
to the wooden framework of homes and other buildings.
The
scientists recommended a six-inch clearance between the insulation and
ground level to deter termite activity. As a result of this research,
the U.S. Southern (Standard) Building Code was modified to require the
six-inch clearance in regions where the probability of termite infestation
is very high. The change has also been adopted for the new International
Building Code.
The researchers are also working with foamboard manufacturers and other groups to develop new products to stop termite movements. In addition, they are evaluating in-ground baiting systems that can reduce or even eliminate termite colonies. And they are studying an above-ground bait system that can be placed inside buildings where there is heavy termite infestation.
