Insects that damage wood
Fortunately, relatively few insects actually damage sound wood. Termites (both subterranean and drywood), carpenter ants and certain powderpost beetles are the primary wood destroying insects. The potential for damage from any of these insects varies by region and climate.
Termites, for example, tend to be of more concern in warm climates whereas carpenter ants tend to be more important in cooler climates. Wood-boring powderpost beetles damage structural wood mostly in coastal climates. Powderpost beetles can, however, damage hardwoods, like flooring and furniture, in any climate.
There are also a number of minor wood damaging insects that may do significant cosmetic damage but rarely impact wood's structural integrity. The table below lists all these insects and their potential for damage. Also, see the Related Articles for additional information about specific wood-destroying insects.
