formosan subterranean termite |
Coptotermes formosanus |
Damage caused by Formosan subterranean termites to a window sill of the Southern Regional Research Center Library. The colony nest was located two floors below in the soil, but workers entered the building through mud shelter tubes that they constructed through the hollow brick walls. The damage went unnoticed until moisture from foraging galleries by the termites caused the paint to blister. Much of the wood had been consumed by the termites before they were detected. |
