Yes, woodworms can indeed cause structural damage to buildings over time. The larvae of wood-boring beetles tunnel through the wood, creating a network of tunnels and weakening the structural integrity of wooden components. While the damage may not be immediately apparent, it can accumulate over the years, potentially compromising the stability of wooden beams, joists, and other structural elements. Therefore, it's essential to address woodworm infestations promptly and take preventive measures to protect the structural integrity of buildings, especially in areas prone to these pests.
