A non-invasive geophysical exploration method, ground penetrating radar (GPR), was used to detect Formosan subterranean termite nests. For the 400 MHz GPR antenna system, the penetration depth of radar pulse was over 100 cm in sand and about 50 cm in clay loam soil. The detectable target size also varied at different depths in different soil types (sand and clay loam). Linear regression models between target size and image size were generated at different depths in sand and clay loam soil by a simulation burial test with two different target types (wood and metal). Two and three dimensional images for a buried carton nest section and 2-D images for an active Formosan subterranean termite nest were also developed. GPR appears to be a useful tool. for detecting Formosan subterranean termite nests.
