Wood-Boring Beetles

Introduction

Many insect species are able to use wood as a food source or as a home. In doing so they can cause serious damage to timber by tunnelling into standing trees, freshly felled logs or wet, decaying timber. A small number, mostly beetles, are able to attack timber in the more or less dry conditions found in buildings. These beetles are often called "woodworm" because it is the larval or "worm" stage that bores into and eats the wood.
