A Brief Guide to Woodworm
By far the most common of Britain's four kinds of woodworm is the grub (or larva) of the furniture beetle.
It bores through wood and can damage furniture, floorboards and rafters. Severe cases can cause structural damage, and make floorboards too weak to walk on.
But this is rare. Furniture beetle is a pest, but it is easy enough to bring under control and eradicate, so should not be cause for alarm. There are far worse things that can happen to a house!
