Although there are a large number of insects found in houses, many of these do not attack timber but are associated with other materials, such as fabrics and foodstuffs.

Insects that attack timber include wood wasps, forest longhorn beetles, ambrosia beetles, bark borer beetle, powder post beetle and house longhorn beetles.
