A wood destroying insect (WDI) inspection is performed to determine if visible evidence of wood inhabiting insects are present as a condition of certain real estate transfers. In Kansas & Missouri HUD/FHA secured mortgages are the most common transaction to require WDI inspections.

HUD requires that a qualified representative holding a state issued pest management license must perform WDI inspection. All visible areas of the structure which are readily accessible at the time of inspection are covered. If evidence of an infestation is found it is reported on a HUD specified form. A typical WDI home inspection requires less than an hour to complete and is normally ordered by the purchaser.
