Many Ohio homeowners assume that cold winters keep termites out. In reality, subterranean termites live deep in the soil, below the frost line, and simply wait for spring warmth to push foraging back toward your foundation. Across Franklin County they are the most economically damaging wood-destroying insect.

The termite in your Columbus yard
The eastern subterranean termite is the species you are likely to encounter in central Ohio. Colonies nest underground, and workers build mud tubes to reach wood above ground while staying shielded from air. Mature colonies send out winged swarmers in spring, typically on a warm day following rain, and finding discarded wings near a window or door is a classic clue. Unlike carpenter ants, termites actually consume wood, which means damage accumulates quietly in hidden spots.
Why older Columbus houses are vulnerable
Century homes in German Village, Victorian Village, Olde Towne East and Clintonville often have fieldstone, brick or block foundations with mortar joints that have crumbled over decades. Wood sills may rest close to the soil, and basement beams can sit against damp masonry. Porches built on piers, wooden steps against the foundation and stacked firewood all add contact points. Newer homes are not immune: slab construction can hide plumbing penetrations, and soil that has been graded for new construction can retain moisture along the footing.
Early warning signs
- Mud tubes on basement walls, piers, or the inside of the garage.
- Wings in spider webs or on window sills in spring.
- Wood that breaks apart easily or appears honeycombed beneath thin paint.
- Sagging floors or doors that suddenly stick.
- Soft wood where it meets masonry in the basement.
How treatment works
A licensed inspector will examine the basement, sill plates, rim joists, porches and exterior wood, probing questionable areas with a screwdriver. Findings are usually summarized in writing. Treatment options typically include:
- Liquid soil treatment applied in a trench around the foundation and drilled through concrete slabs, porches and basement floors where needed.
- Baiting systems that use in-ground stations to deliver slow-acting material to the colony.
- Targeted wood treatments for localized spots, accompanied by moisture correction.
Cold weather can affect scheduling but rarely makes treatment impossible, since technicians can drill and treat through basement slabs in winter. Ask each provider to explain its method, what monitoring follows, and what the terms say.
Reducing the odds
- Fix the grade so the soil slopes away from the foundation.
- Keep gutters working and extend downspouts several feet.
- Remove old wooden forms, stumps and scrap lumber near the house.
- Run a dehumidifier and repair leaks in basements.
- Have an inspector check any home before you buy it, particularly an older one.
Columbus termite FAQs
Can termites infest a home with a finished basement?
Yes. Wall coverings can hide activity for years, so inspectors look at utility chases, rim joists and any exposed wood.
Is spring the only time I need to worry?
No. Swarming is seasonal, but workers feed continuously below ground, and heated basements keep them active.
Are carpenter ants the same thing?
Not at all. They excavate damp wood for nests rather than eating it. Treatment differs, so identification matters.
Does homeowner insurance cover termite damage?
Policies commonly exclude it, so check yours with your insurer and consider preventive inspections.
Termite control in Columbus is about catching small problems early. A short inspection costs far less time and trouble than rebuilding a rotted sill plate, so reach out when you notice anything suspicious.
