What is a wood destroying insect (WDI)?

A thorough WDI Termite Inspection can often determine whether or not a building or structure has an active infestation.

Wood Destroying Insects like Termites, Carpenter Ants, Wood Boring Beetles and other Wood Destroying Insects or Organisms (WDI/WDO), cause significant damage to homes and buildings here in Massachusetts and across the U.S.

Wood Destroying Insects WDI and Wood Destroying Organism WDO, essentially mean the same thing. Some organizations refer to wood destroying pests as insects while others call them organisms.

Most wood destroying pests are both insects and organisms so both terms are appropriate and often used synonymous.

However, there are some organisms that are a wood destroying fungus and not actually an insect.
