Wood Destroying Insects Inspection

The Wood-Destroying Insect (WDI) Inspection license is part of Ohio Pesticide Law and therefore requires the inspectors to obtain an Ohio Commercial Pesticide Applicator License.

What is wood destroying insect inspection?

This inspection represents all the wood destroying insect infestation and/or damage which may exist as of the date of the inspection. For purposes of this inspection, wood destroying insects include termites, carpenter ants, carpenter bees, and re infesting wood boring beetles.



A WDI Inspection is a thorough examination of a property to determine if there are visible signs of wood-destroying insects. During the WDI Inspection, a pest control technician will also look for signs that a property has previously been treated and whether the treatment is ongoing.

Although the most common wood-destroying insects lurk inside the wood, there are a few noticeable signs that can alert you to an issue such as softwood that emits a hollow sound when tapped and blistering or darkening wood. For termites, look for discarded wings near doors or

windowsills, small piles of feces that look like sawdust, or dry, brown mud tubes on the exterior of a structure that resemble pencil-thin tunnels.

If your home is less than three years old, you may not find any visible evidence of termites since it could take three to eight years before signs of an infestation can be seen with the naked eye.  

Since prevention is best, you can take steps to keep wood-destroying insects from devouring your home, regardless of its age. The National Pest Management Association (NPMA) recommends:

  • Eliminating or reducing moisture in and around a property
  • Repairing leaky faucets, water pipes, and air conditioning units
  • Repairing worn or rotted fascia, soffits, and shingles
  • Replacing weather stripping or loose mortar around foundations and windows
  • Installing downspouts, gutters, and splash blocks to divert water.
  • Maintaining an 18-inch space between the soil and any wooden part of a structure
  • Storing firewood, a minimum of 20 feet from a structure
  • Consider scheduling an annual WDI Inspection.

If you are working with the Department of Veterans Affairs, Federal Housing Administration, or the Department of Housing and Urban Development to purchase a property, you will be required to have a WDI Inspection. In addition, most banks require, or at least recommend, that a WDI
Inspection is completed prior to authorizing a mortgage.

Whether or not a WDI Inspection is required, be sure to look for visible signs of wood-destroying insect infestations as mentioned above anytime
you are touring a property. You could save thousands of dollars on costly repairs or treatments that are not covered by insurance.

"We want to let you know how thoroughly please we are with the service you provided us as we were building our home. Your expertise was apparent and your customer attentiveness was exemplary. One of the things I liked about your service, among many others, is how you were always on time when we were scheduled to meet at the site. Another is how you acted as an advocate for us. It almost seemed as if you are taking meticulous care of your own home and not someone else's. I appreciate how you got the city to put in a drain at the end of our street and how you contacted people in authoritative positions to be sure that certain things were accomplished and how you attended the drywall walk through on my behalf while I was out of town on business."
