Wood-Destroying Insects

Wood-Destroying Insect Inspection: what it covers

Quick answer

A wood-destroying insect inspection in Columbus checks the structure for termites and other insects that damage wood. OSU’s training listing places termite and wood-destroying insect control in Ohio Department of Agriculture category 10b, separate from general pest control. The report states what was checked and what was found.

Wood-Destroying Insect Inspection illustration for Columbus, OH

Wood-destroying insects are a separate kind of inspection from a general pest visit. The concern is the structure: the sill, the joists, the posts and the framing that hold the house up. A general visit may look at the kitchen and the attic; a wood-destroying insect inspection looks at the wood that carries the load, and at the soil and moisture that reach it.

The Ohio training listing from OSU describes structural pest control as a set of categories. Category 10 covers domestic, institutional, structural and health-related pest control, and it is split into 10a general pest control, 10b termite and wood-destroying insect control, 10c fumigation and 10d vector control. Those categories are why this inspection is named on its own.

Warning signs

Signs you need wood-destroying insect inspection

Work in a crawl space with a dust mask or respirator and gloves, and do not enter a space with a damaged or unstable floor above.

Keep children and pets out of the inspection area, and do not remove wood that is part of the structure without a contractor’s advice.

  • A floor that sags or gives in one area, or a door that sticks in its frame
  • Wood that sounds hollow or crumbles when probed near the soil line
  • Mud tubes or galleries in wood that has been opened during a renovation
  • Frass or fine sawdust below a timber or in a crawl space
  • Cracks in plaster or drywall above a sill, with no other cause visible
  • A crawl space with standing water and wood showing staining or softness
Our process

How our wood-destroying insect inspection visit works

  1. Scope the building

    The inspector confirms the type of foundation, the framing, the crawl space or basement, and any area that is not accessible, and writes the scope at the start of the report.

  2. Inspect the structure from the outside in

    The outside walk checks the grade, the soil line, the wood contacts and the foundation cracks. Each is recorded by location.

  3. Inspect the interior and the framing

    Accessible interior areas are checked with a light and a probe. Where a wall is closed, the report says so and the limit is stated.

  4. Take readings where the wood looks suspect

    A moisture meter reading is taken at each suspect point, and the readings are written next to the location, so the report can be read by someone else.

  5. Write the report by category

    The report lists what was found, where, and what it means for the structure. Where the finding involves a licensed category of work, the report names the category in plain words.

How is a wood-destroying insect inspection different from a general visit?

A general visit looks for pests across the building. A wood-destroying insect inspection looks at the wood that carries the structure and the conditions that reach it, and it reports on that wood by location.

The difference is in the questions asked. A general visit asks where the pest is and how to remove it. A structural inspection asks whether the wood is sound, whether the moisture is reaching it and whether the insects are active in it. The answers are reported in terms a builder or a lender can read.

A homeowner who needs a report for a sale, a loan or a renovation should say so at the start. The report is then written to show the scope, the findings and the limits in a form that the requester can use.

What do the Ohio categories mean for this work?

OSU’s training listing places termite and wood-destroying insect control in Ohio Department of Agriculture category 10b, separate from general pest control in 10a. A business doing this work should be able to say which category its applicator holds.

The categories exist because the work is different. A general treatment uses products for household pests, and a structural treatment uses methods and products suited to wood and soil. The applicator’s licence in the right category is the credential that matters for that work.

The OSU listing is a 2019 training page, so the category detail should be confirmed with the Ohio Department of Agriculture before it is quoted in any contract. This page states the category as the training listing gives it, and no more.

What should the report say about the wood?

The report should say which wood was checked, what its condition was, what readings were taken, where any activity was found and what could not be reached. Vague wording is not a finding.

A line such as the sill was sound at the points probed, with readings at the north and east corners, is the kind of statement that can be checked later. A line such as the house is clean is not, and a report should avoid it.

Where the inspector cannot reach a joist, the report says so and gives the reason, such as insulation or a finished ceiling. That line protects the requester and tells the next inspector what to open.

When is a structural repair needed, and who should do it?

A structural repair is needed when wood has lost the strength it needs to carry the load. The inspector recommends the repair and its urgency, and a qualified contractor carries it out to the standard the structure requires.

A soft sill or a damaged joist is a repair that affects the structure, and the inspector does not make it a pest task. The report marks it as a structural item, recommends a qualified contractor and explains why the repair is needed.

The pest work and the structural work can run side by side. The report separates them, so the homeowner knows which items are for the applicator and which are for the contractor.

What about a house with a moisture problem?

Moisture is the condition that most often lets wood-destroying insects and decay into the structure. The inspector records the moisture, its source and the recommended change, and the change is part of the report.

A damp crawl space, a downspout that empties at the wall or a grade that slopes toward the house is recorded as a condition. The report recommends the change, such as extending a downspout or regrading, and it notes that the change should be made before any treatment.

A recurring damp reading in the same place is a sign that the water path has not been fixed. The report says so and recommends a drainage check by someone able to carry out the work.

What should a buyer or lender receive from this inspection?

A buyer or lender should receive the scope, the findings by location, the readings taken, the limits of the check and the recommendations, in a single written report that can be read without the inspector present.

The scope section tells the reader what was looked at and what was not. A reader who sees that a crawl space was entered on one side only knows to ask about the other side. The findings are then listed with their positions, so a contractor can find each one on the day of the repair.

The recommendations are kept apart from the findings. A finding is what the inspector saw; a recommendation is what the inspector advises. Keeping them apart lets a buyer or lender judge the report on its own terms and decide what needs a second opinion.

Franklin County

Why wood-destroying insect inspection is different in Central Ohio

Older Columbus houses with stone or brick foundations and timber framing are the usual subject of a structural inspection, because the wood and the masonry meet at points that need reading by hand.

Homes across Franklin County that were renovated over several decades can have joints where old and new framing meet, and the inspection records those joints as a separate item.

The sources give no local rate of wood damage for Columbus, so the report describes what it finds in the building and does not compare it with the neighbourhood.

FAQ

Wood-Destroying Insect Inspection FAQs

Do I need this inspection for a home sale?

A homeowner selling a house may be asked for one by a buyer or a lender. This site does not set that requirement; the buyer or lender states what they need, and the report is written to that scope.

Is a structural repair part of the inspection?

The inspection recommends it and states its urgency. The repair itself is carried out by a qualified contractor, not as a pest service.

Is the licence category important here?

Yes. The OSU listing places termite and wood-destroying insect control in category 10b. Ask the business which category its applicator holds.

Does the report guarantee the wood is sound?

No. It records what was checked and what was found, and states what was not reached. It is not a guarantee of the structure.

How long does the report take to arrive?

The report is written after the visit and sent in writing. The timing is agreed when the inspection is booked, and a rush request is discussed with the inspector before it is accepted.
