ANSWER

The bottom line is insects just don’t feed on steel. The EPS portion of the panel is of a modified type, which offers no food value for insects. Certain species of termites will find ways to pass through minute cracks in concrete to get to their favorite food - wood. Likewise they have been known to bore their way through EPS to get to wood and ants have been known to nest in certain types of EPS. The problem has been corrected by soil treatment, by creating barriers between the panels and the slab and by treatment of the panels. TAMBOR™ is an approved insecticide that can be applied into the bottom track to provide a barrier.
