Woodworm in your house? Be extra vigilant.

When purchasing a new home, the last thing you want to discover is an infestation of longhorn beetles lurking within the wooden structures, potentially causing extensive hidden damage. Understanding how to identify and address such issues before closing the deal can save you from costly repairs and legal disputes, ensuring your dream home doesn't become a nightmare.
When viewing your potential new home, it's probably not the first thing you think of: the longhorn beetle. Yet, this small rodent can cause considerable problems, especially if you only notice its presence after signing the purchase contract.

House longhorn beetle

There are many species of beetles called longhorn beetles, but homeowners are likely to experience problems only from the so-called house longhorn beetle. This house longhorn beetle hatches from an egg and lives as a larva for a very long time, up to 12 years, before finally becoming a beetle. The longhorn beetle larvae live in wood: by gnawing, they create tunnels that can cause serious damage to the wood.

Long-term hidden defect

Sometimes this damage is visible through drill holes in the wood or through visible drill dust. In many cases, however, the damage is invisible, making it a hidden defect. This defect can be expensive: the longhorn beetle must be removed, and wooden structures will need to be replaced. Longhorn beetles can damage support beams and roof structures, among other things.

Liability

Whether a home buyer can recover hidden woodworm damage from the seller depends on several factors. A buyer must be able to assume they can use the property normally. If this is not the case, in many cases the seller is liable and must repair the defect. While the presence of woodworm doesn't necessarily impede normal use, it can if there is serious damage to roof structures , floor joists, and supporting beams.

Construction technical inspection

If the buyer was aware of the damage caused by woodworms, the seller is obviously not liable. The sale price will likely have been reduced due to the presence of the defect. Even if the damage was clearly visible to the buyer, the seller's liability is waived. The buyer is expected to thoroughly investigate any defects themselves.
