Holzwurm, also known as woodworm or timber beetle, refers to a group of wood-boring insects that target both hardwood and softwood structures. These pests are a concern for homeowners because they can silently damage wooden components, leading to structural issues in buildings. The larvae of these insects create tiny exit holes in the wood as they mature, and their tunneling activity weakens the wood. If left untreated, Holzwurm infestations can compromise the integrity of wooden structures, posing a significant risk to property value and safety.
