Eastern subterranean termites · Orange County, NY
The termite that lives here is the eastern subterranean termite. It nests in the soil, travels in mud tubes and eats the wood of your house from the inside out, quietly, for years. Most people find out on a warm spring day when a cloud of winged insects appears in the basement. A local inspection tells you what you are dealing with and what it will take.
Swarmer ID
Every spring, a lot of Orange County homeowners panic over winged insects that turn out to be ants, and a fair number shrug off winged insects that turn out to be termites. Telling them apart is not hard once you know where to look.
Termite swarmers are dark brown to black and about three-eighths of an inch long including the wings. The waist is thick, so the body looks like one straight tube. The antennae are straight and beaded, like a tiny string of pearls. Most telling are the wings: two pairs of the same length, pale and slightly milky, extending well past the end of the body. They break off easily, so a little drift of shed wings on a windowsill is often the first clue.
Winged ants, including carpenter ant swarmers, have a sharply pinched waist, elbowed antennae that bend like a knee, and a front pair of wings that is clearly longer than the back pair. If that is what you have, our carpenter ant control page is the right place.
Termite swarms indoors usually happen in the morning or midday on a warm day following rain, and they are short. Swarmers are drawn to light, so they end up on windows and patio doors, then die within hours because they cannot survive in dry indoor air. A swarm inside means a mature colony has been feeding in or under the house for some time.
Swarms are seasonal. These signs are there year-round if you know where to look.
Subterranean termites are found throughout the county, and in practice the risk follows moisture and wood-to-soil contact more than geography. Still, some housing types come up again and again.
Older homes with wooden porches built right down to grade, sill plates on low fieldstone foundations, and additions with crawlspaces are frequent finds in village centers like Washingtonville, Walden and Port Jervis. A century of grade changes, garden beds raised against the siding and gutters that dump water at the corners create exactly the damp wood termites need.
River towns on the Hudson Riverfront and the Upper Delaware deal with high water tables and wet basements, which keeps soil moist right against the foundation. In the low, damp ground near the Black Dirt farms, the soil stays wet late into the season.
Newer construction is not exempt. Slab-on-grade homes, finished basements and houses with rigid foam insulation below grade give termites hidden paths through cracks and behind the foam, where tubes are almost impossible to see without removing finishes. Wood mulch piled high against a new foundation does not help either.
There is no single right answer. The inspector will suggest an approach based on construction, access, wells and how active the colony is.
A termiticide is applied to the soil around and under the foundation by trenching outside and, where needed, drilling through slabs, porches and garage floors. Modern non-repellent products are picked up by termites passing through and shared with the colony. Properties with a private well need extra care in how and where this is done.
Stations are set in the soil around the house and monitored. When termites find them, the bait inside slows their growth and the colony declines over time. Baits involve less drilling and very little chemical, but they need ongoing monitoring visits.
Foams and borate treatments go directly into infested wood or wall voids. These usually support a full treatment rather than replacing it, and borates are also used on exposed framing during renovations.
Breaking wood-to-soil contact, regrading, fixing gutters and pulling back mulch. Damaged framing gets repaired by a contractor, often after treatment so new wood is protected.
Colonies move deeper in the soil but keep feeding where they can reach heated foundations and wood in contact with warm ground.
Swarm season. Mature colonies send out winged reproductives on warm days after rain. Most indoor swarms happen now.
Peak feeding. Mud tubes are easiest to spot and treatments work well with soil conditions.
Good time for inspections, real estate checks and treatment before the ground freezes.
Buying or selling a house in Orange County?
Many mortgage lenders, especially for FHA and VA loans, ask for a wood-destroying insect inspection, often written on the standard NPMA-33 form. It covers termites, carpenter ants and other wood-boring insects. Local pest control companies do these routinely, and they typically need to be done within a set window before closing, so schedule it early.
Termite work is quoted after an inspection. These are the details that change the number most.
| Factor | Why it matters |
|---|---|
| Linear feet of foundation | Liquid treatments and bait layouts are measured around the perimeter, so a long ranch costs more than a compact colonial. |
| Construction type | Slabs, porches, stoops and finished basements need drilling. Crawlspaces need access. Fieldstone takes more labor than poured concrete. |
| Treatment method | Liquid treatments are a bigger upfront job. Baits spread cost over a monitoring contract. |
| Private well or nearby water | Requires adjusted methods and setbacks, which can add time. |
| Extent of infestation | Active swarming colonies and multiple infested areas take more work than a single tube on a pier. |
| Warranty and renewals | Many companies offer an annual renewal for re-inspection and retreatment if termites return. Ask what is covered. |
Repairs to damaged wood are usually quoted separately by a carpenter or contractor.
Honestly, not well. Hardware store termite stakes and spray cans do not reach the colony in the soil, and effective soil treatments use specialized equipment, a lot of finished solution and drilling through concrete. In New York, applying pesticides for hire requires DEC certification, and the people doing it every week know how to work around wells, drains and heating oil lines without contaminating anything.
What you can do is reduce the risk: keep gutters and downspouts directing water away, keep firewood, lumber and cardboard off the ground and away from the foundation, leave a gap of several inches between mulch or soil and the siding, and fix plumbing leaks quickly. Those steps also make your house less attractive to carpenter ants, millipedes and house centipedes, which all love damp foundations.
Searching "termite inspection near me" or "termite exterminator near me" in April usually turns up a long list of big companies. We point you to independent Orange County pest control operators instead, people who inspect the old porches of Goshen and the slab homes of the Town of Wallkill every season.
If you have swarmers, a closing date or a contractor who just opened a wall and found mud, let us know when you call. Those details help get the right inspector out quickly.
Yes. Eastern subterranean termites are found across New York's Hudson Valley and much of the state. They are slower acting than termites in the South, but damage still adds up over years if a colony goes unnoticed.
No. Swarmers are the reproductive stage and die quickly indoors, but the colony that sent them is still in the soil and likely feeding on the house. Keep a few for identification and schedule an inspection.
That depends on the product and method. Modern liquid termiticides are labeled to protect for a number of years under normal conditions, and bait systems protect as long as they are monitored and maintained. Ask about the warranty and renewal terms.
Generally no. Most soil treatments happen outside and around the foundation, with some drilling inside. Your technician will tell you about any areas to keep kids and pets away from until they dry.
