Final answer:
The presence of Old House Borers can be detected using acoustic emission detectors that pick up the sounds of larvae chewing through wood, as well as visual inspection for exit holes and frass. Pheromone traps can also be used by professionals for monitoring and control.
Step-by-step explanation:
The Old House Borer, which is a type of beetle known scientifically as Hylotrupes bajulus, can be detected using various tools and methods.
Specifically, acoustic emission detectors are often used to detect the presence of these wood-boring beetles. The larvae of the Old House Borer beetle produce distinctive sounds as they chew through wood, which these detectors can pick up.
Additionally, visual inspection for telltale signs of infestation, such as exit holes in wood or the presence of frass (fine, powdery sawdust), can indicate the presence of these beetles. In some cases, pest control professionals may also use pheromone traps to monitor or control Old House Borers.
