Abstract

The effectiveness of physical barriers against subterranean termites was evaluated in a 34-week field test in coastal Mississippi by installing Obex11, a commercial polyethylene flashing, and Termimesh, a stainless-steel mesh in 3-ply 280mm(width) x 450mm(length) cross laminated timber (CLT) walls. Damage showed that both barriers performed significantly better than the no barrier control with respect to termite damage as evaluated by visual rating and mud tube length.  Obex11, however, like the no barrier control, was more vulnerable to attack by Ambrosiodmus minor (Stebbing), an invasive ambrosia beetle, with both treatments exhibiting significantly longer bore trails than those found in Termimesh.
