  • Termites: Termites are among the most well-known of the wood-eating insects and when they come into contact with wooden buildings or wood in buildings, they can cause a lot of damage, and even weaken the supports of a house.
  • Wood-Boring Beetles: While termites eat decaying or refined wood products, wood-boring beetles eat living trees as well as timber. However, this does not prevent them from boring into and damaging buildings. It is the larval form of the beetle that bores into and eats wood. They spend most of their larval life cycle chewing small tunnels through wood, only lasting long enough as adult beetles to mate and lay eggs.
  • Horntail Wasps: Horntail wasps larva may lie dormant in the wood long enough for it to be made into lumber, causing minor damage when they emerge as adults. Just like beetles, they eat wood as larvae and this is where they do most of their damage.
