What is the best evidence of dry wood termites?

The best evidence of dry wood termites is their six-sided fecal pellets. These pellets, also known as frass, are a clear indicator of termite activity because dry wood termites consume wood as their primary food source and excrete these distinctive pellets as waste. The shape and size of these pellets are characteristic, and they typically accumulate near areas where termites are infesting wood.

In contrast, wood shavings may indicate other types of wood-destroying insects or even normal wear and tear in wooden structures. Discolored wood could suggest a variety of issues, including moisture damage or decay unrelated to termites specifically. Crumbling wood may also result from structural damage or other pests and does not provide the distinctive evidence that the unique fecal pellets of dry wood termites do. Therefore, the presence of these six-sided fecal pellets serves as a definitive sign of dry wood termite infestation.
