What identification feature is associated with the old house borer?

The identification feature associated with the old house borer is long antennae with two black marks on the thorax. This distinctive characteristic helps differentiate the old house borer from other wood-boring beetles. The long antennae are particularly notable, as they give the insect a unique appearance that can be easily recognized in the field.

The two black marks on the thorax serve as a visual cue for identification, making it easier for pest control professionals to determine the presence of this specific borer. Knowing this feature is essential for effective pest management and ensuring appropriate methods for treatment and prevention are applied. The old house borer's recognition is crucial as it can cause significant structural damage, particularly in older wooden structures, thus emphasizing the importance of accurate identification in termite and pest control practices.
