Structural Pest Damage
Wood can last for centuries if protected from moisture and insect attack. However, if not sufficiently protected, wood will decompose naturally due to moisture intrusion which causes fungi, rot, and decay. Additional moisture can also create conducive conditions for insects that eat the fungi or the wood itself.
Pests such as subterranean termites, powderpost beetles, carpenter ants, carpenter bees, and drywood termites can cause significant structural damage to a home. For example, termites cause the most destruction with national costs for control and damage exceeding $1.5 billion a year. Beetles are next in line with the amount of damage caused nationally on a yearly basis. Depending on the geographical location, bees, wasps and ants follow third, as do wood-inhabiting fungi.
