What is the primary method for identifying drywood termites?

The primary method for identifying drywood termites is through the observation of drywood fecal pellets. These pellets, often referred to as frass, are a distinctive sign of drywood termite activity. Unlike subterranean termites, which tend to leave their droppings in mud tubes or debris, drywood termites produce pellets that are small, oval, and have a smooth surface. They can typically be found near infested wood, where the termites have been feeding and excreting waste.

The presence of these pellets is crucial in identifying an infestation, as they indicate not only the activity of the termites but also their location and the severity of the infestation. This method is especially effective because each species of termite can produce fecal pellets that vary slightly in shape, size, and color, allowing for a more precise identification of the species involved.

While live observations, wood damage inspections, and sound tests can provide additional information regarding termite presence, they are not as definitive as finding fecal pellets, which directly indicate drywood termite activity. Observing damage may suggest infestation, but without the confirmation from fecal pellets, it isn't enough to establish the presence of drywood termites conclusively.
