Yes, woodworms can indeed cause structural damage to your home if left untreated. They often target wooden beams, flooring, and other load-bearing structures. Over time, the larvae create tunnels within the wood, weakening its structural integrity. This can result in sagging floors, creaking beams, and, in severe cases, the risk of structural failure. To prevent such damage, it's crucial to address woodworm infestations promptly, especially in areas where the structural stability of your home relies on wooden components.
