Evaluation of Lahar barrier to protect wood structures from Philippine subterranean termites

Issue Date

Abstract

Volcanic debris consisting of a sandy aggregate (lahar) from Mt. Pinatubo Central Luzon, Philippines was used as physical barrier to prevent tunneling and penetration of Philippine subterranean termites into a small wooden structure. The protective barrier consisting of mixed lahar particles was installed beneath floor and concrete foundation walls. Regular inspections were made over a five year period to determine signs of termite damage inside and outside of the structure. Results showed that Philippine subterranean termites were unable to penetrate the 5.0 cm thick layer of 1.18 to 2.40 mm lahar particles from the underground soil. The structure remained in good condition with no sign of termite damage to the wooden interior. The study indicated that lahar barrier could be used to protect wooden structures from entry of subterranean termites and offer a non-chemical alternative to commercially available termiticides.
