What type of materials do deathwatch beetles typically infest?

Deathwatch beetles primarily infest hardwoods rather than softwoods, plastic woods, or metals. These beetles are known for their association with damp, decaying wood, which is often found in structures, furniture, and even flooring made of hardwood. The larvae of deathwatch beetles tunnel and feed within the wood, which can lead to significant damage over time. Hardwoods, due to their density and the type of organic material, provide an ideal habitat for these pests, enabling them to thrive. Thus, the correct identification of hardwoods as their primary target reflects an understanding of the ecological preferences of deathwatch beetles and their impact on wooden structures and items. Understanding this relationship is crucial for pest control and prevention strategies in environments where hardwood materials are prevalent.
