In Ohio, termite inspections are regulated and part of a Wood Destroying Insect (WDI) inspection. During a WDI inspection, licensed inspectors look for signs of activity of termites, carpenter ants, carpenter bees and powderpost beetles. WDI Inspectors must complete mandatory training, pass two exams and complete continuing education to obtain an Ohio WDI license. Often, a WDI inspection is required by your mortgage company before closing to ensure the property is free from infestation. Whether or not your mortgage company requires it, a WDI inspection is a small investment to provide you with peace of mind.
