Coptotermes formosanus

Occasionally the foraging tubes may be observed on the wood surface or tree trunk. During the swarming season (April to June), elongated mud tubes that serve as flight exit slits may be seen. The damage by C. formosanus tends to occur in places with high moisture including the bathroom, kitchen sinks and leaky roofs. An acoustic emission device (AED) may be used to locate sites with feeding activity, but most AEDs have a limited detection range (Scheffrahn et al., 1993).
