Termites in central Ohio: the species and the risk rating

There is effectively one termite that matters here. Reticulitermes flavipes, the eastern subterranean termite, is the most common and widely distributed termite species in the continental United States, and it is what Ohio structures contend with. Ohio’s risk of subterranean termite infestation has been rated moderate to heavy in United States Department of Agriculture work on the subject, cited by Ohio State University’s diagnostic programme.

They colonise differently from what most people picture. A subterranean termite colony has no single defined nest territory. It occupies multiple food sources linked by underground tunnels, each one a satellite nest that may contain its own reproductive. The colony is not territorial and shifts with food availability. That structure is why treating the spot where you saw damage rarely ends anything.

Reading the evidence yourself before anyone quotes you

Swarms. In Ohio, these termites swarm over spring and early summer. A swarm is the most common way an infestation is first detected, and in an infested house it can put tens of thousands of winged termites indoors at once. They head for windows and artificial light, and the shed wings they leave on sills and floors are themselves a sign of active infestation.

Telling them from flying ants. Termite alates have straight antennae, four wings of roughly equal size, and a waist with parallel sides. Ant alates have elbowed antennae, forewings noticeably larger than the hind wings, and a pinched waist. Termites also shed their wings quickly after landing; carpenter ants do not.

A correction worth having. Homeowners often assume termites came up through a sink or a drain. They cannot. Ohio State’s diagnostic clinic has addressed exactly this scenario: these insects cannot navigate through or survive in water, so a plumbing fixture is not a route of entry. Winged termites appearing in a basement almost always mean the colony is already in the structure and has built an above-ground tube to release the swarm.

Mud tubes. Workers desiccate in open air, so they build shelter tubes out of soil, faeces, saliva and cellulose to cross exposed surfaces. Look on foundation walls and pillars close to soil.

The wood itself. Subterranean termite galleries run with the grain and contain soil and faecal spotting. Heavily damaged timber can be hollow while the outer surface stays intact, so blistered or lumpy paint is worth pressing on.

Dublin’s two building stocks

Dublin was platted in 1810 by John Sells, and named by the surveyor John Shields after Dublin in Ireland. Historic Dublin still carries early nineteenth-century buildings and the dry-laid limestone fences that line its older roads. That is one Dublin.

The other began in 1972, when construction started on the Muirfield golf course and residential community after Jack Nicklaus selected the site; 3,914 acres were annexed into what was then the Village of Dublin. The population was 681 in 1970. By the 1990 census it was 16,366 — a rise of around 350 per cent — and it has since passed 35,000.

For termite work the distinction is practical rather than sentimental. Older structures near the historic core tend to have masonry and stone foundations, crawl spaces, and a century of accumulated wood-to-soil contact, buried stumps, added porches and rebuilt steps. Post-1972 subdivision construction is generally tighter, but concentrates risk in a small number of repeatable places: expansion joints, plumbing and utility penetrations through the slab, porch and stoop voids, and mulch beds run up against the foundation.

The prevention work that is genuinely yours to do

Ohio State’s guidance on subterranean termites is specific and most of it costs nothing but a Saturday. Remove wood-to-soil contact, including buried form boards, old steps and stacked timber against the house. Seal cracks and crevices in the foundation where practical. Manage water properly — a pitched roof, correctly installed downspouts, clean gutters, drain tiles, and soil graded away from the foundation — because good water management reduces the moisture available for termites to transport back to the nest.

Mulch has two numbers attached. Keep the mulch level at least six inches below the foundation, which both reduces access to wood inside the structure and leaves you an inspection strip to look for mud tubes. And keep mulch shallow, under about two inches, so the soil beneath stays drier.

Soil treatment or bait stations

Both are legitimate and a company recommending one should be able to explain the trade-off rather than just naming a brand.

Liquid soil termiticide is applied around the building perimeter, and termites are exposed while tunnelling through treated soil. Non-repellent products are the modern norm precisely because termites do not avoid them, and their slow action lets the toxicant move through the colony. The weakness is physical: soil shuffles naturally from root growth, animal activity and water flow, which opens gaps in the treated zone over time.

Bait stations are installed around the perimeter at roughly ten-foot spacing and use far less chemical with less run-off risk. Their weakness is that termites have to find them, which is why pre-baiting with untoxicated matrix is sometimes used first to establish where termites are actually active.

What an Ohio company should hand over on request

Ohio State University Extension publishes a list of documents a pest management company should be willing to supply if you ask. It is short, specific, and almost nobody asks for it:

• Its Ohio Department of Agriculture business licence and applicator licence
• Its certificate of insurance
• Its workers’ compensation certificate
• The Safety Data Sheets and specimen labels for the products it intends to use

The last item is the one people skip and the one most worth having. A specimen label tells you what is going around your house, and it is the legal document governing how that product may be applied.

Extension also flags behaviour that should end a conversation. Be wary of a company that pressures you to sign on the spot, that will not show you the pest or the evidence of it, that cannot produce Ohio Department of Agriculture licensing or proof of insurance, that disparages competitors’ products as illegal, or that quotes far outside the range of everyone else. And one specific claim is always false: no city, the State of Ohio, Ohio State University, the Ohio Department of Agriculture, the Ohio Department of Health nor the United States EPA endorses pest control companies. None of those bodies does endorsements. A company claiming otherwise is telling you something useful about itself.

Exterminator Dispatch routes the call and nothing further. The licensed company that takes it owns the inspection, the recommendation and its own pricing, and you remain free to keep shopping.
