Termites in New York City — Where They Actually Turn Up

People are often surprised that New York City has termites at all. It does: the Eastern subterranean termite (Reticulitermes flavipes) is found across the city wherever wood meets damp soil. Formosan termites are not established here, and drywood termites are not a New York problem.

Honestly assessed, risk varies enormously by building. Wood-frame detached and semi-attached houses — common in Staten Island, Queens, much of Brooklyn and parts of the Bronx — carry real risk. Brownstones and masonry row houses have timber joists, cellar stairs and posts inside the masonry shell, and that is where we find damage. Masonry high-rises are low risk, though not zero where wood meets a damp cellar floor; a swarm in a high-rise lobby is far more often ants.

Swarmer or flying ant? Three features settle it:

• Wings. A termite swarmer has two pairs of wings of equal length, extending well beyond the body and shed within hours. A winged ant's front wings are clearly longer than its hind wings.
• Waist. Termites are broad-waisted, almost tubular. Ants are pinched sharply between thorax and abdomen.
• Antennae. Termite antennae are straight and beaded. Ant antennae are elbowed.

The evidence left behind is usually more useful than the insects. Shed wings in piles on sills and basement floors. Mud tubes, pencil-width earthen runways up a foundation wall, a pier or a pipe, which workers build because they dry out in open air. And damaged wood: termites eat the softer springwood and leave the harder bands, so the galleries follow the grain and are packed with soil and faecal material. Hollow-sounding wood or blistered paint on a sill is worth probing.

The common look-alike is the carpenter ant (Camponotus pennsylvanicus). It nests in wood rather than eating it, so its galleries are clean and smooth, with coarse frass of shavings and insect parts pushed out. Soil in the galleries means termites; clean galleries and a sawdust pile mean ants and, nearly always, a moisture problem.

Where Termites Get Into City Buildings

Subterranean termites enter from the soil, so the work is at and below grade — usually in the cellar and the yard, not the rooms where people notice wings.

• Cellar floors and wood on concrete. Old cellars often have wooden posts, stair stringers, partitions and shelving resting directly on a cracked slab or a dirt floor. Cracks and the joint where the floor meets the wall are the route up.
• Joist ends in masonry walls. In brownstones and older row houses the joists sit in pockets in damp foundation and party walls. A persistent leak there makes the joist ends attractive and hard to see.
• Stoops, areaways and rear extensions. Fill under stoops, wooden areaway steps, and rear additions on slabs joined to an older foundation.
• Yards and planting beds. Soil and mulch piled against a frame house, wooden fences and decks against the building, and old stumps or buried wood in the yard.
• Water. Leaking leaders, backed-up yard drains and plumbing leaks in the cellar keep the soil and wood damp. Warm boiler rooms extend the season.

In attached rows one colony forages under several buildings.

Treatment Options in a City Building

City buildings rarely offer a clean run of open soil around the foundation, so treatment is usually a combination: drilling the cellar slab along the foundation and around penetrations, treating whatever soil is accessible in yards and planting strips, and baiting where drilling is impractical.

Liquid soil treatment puts a continuous treated zone where termites travel to reach the building: a narrow trench along open foundation, with rodding below it toward the footing, and drilling at close intervals through slabs, porches and cellar floors, which are then patched. Volume is the whole game, applied to the product label.

Non-repellent or repellent. Non-repellents — fipronil, imidacloprid, chlorantraniliprole — cannot be detected, so workers pass through, pick up a dose and carry it back. Repellent pyrethroids such as bifenthrin form a barrier the insects avoid, which only holds if it has no gaps.

Baiting systems work the other way round. Monitoring stations go into the soil around the building and are checked on a schedule; once termites are feeding, a cellulose bait with a chitin synthesis inhibitor (noviflumuron, hexaflumuron) goes in, which stops workers moulting. The colony declines over months. Slower, but it targets the colony and needs no drilling.

Spot treatments and borates. Foam injected into an active gallery kills the termites in that wood, not the colony in the soil. Borate (disodium octaborate tetrahydrate) on bare, unfinished wood protects that timber — ideal when joists and sills are exposed during renovation — but does nothing to the soil.

Why do-it-yourself products fail. Spraying a visible tube kills a handful of workers while the colony, foraging over tens of metres of soil, builds another. Consumer products cannot reach the depth and volume a foundation needs. Breaking a tube and watching whether it is rebuilt is useful diagnosis, not treatment.

Treatment stops termites; it does not restore a weakened joist. Damaged load-bearing members need a contractor or engineer, and the report gives them the locations.

Responsibility, Records and Selling in New York City

If you rent, termite damage to floors, stairs, joists and other structure is a building condition, and the Housing Maintenance Code places the duty to keep a multiple dwelling in good repair on the owner. Report it to the owner in writing with photos and keep a copy. If it is not addressed, a 311 complaint to HPD is the route for conditions in the building. Termites are not among the pests named in the indoor allergen hazard law, so do not expect that law to be the lever here — the repair obligation is.

For co-op and condo boards, cellars, foundations and structure are common elements. A dated written report naming locations, damage and conducive conditions turns a complaint into a budgeted decision, and it is what an engineer or buyer will ask for later.

The NPMA-33 report. The Wood Destroying Insect Inspection Report is the standard form used in real estate transactions here, routinely requested by buyers and lenders. It records whether visible evidence of termites and other wood-destroying insects was found, where, and whether there is visible damage. Two things it is not: it is not a warranty that the building is free of termites, and it is not a structural assessment. It is a visual snapshot of the accessible areas on the day. Finished walls, stored contents and floor coverings hide evidence; read the section listing what could not be inspected.

Ask for the applicator's New York State certification before any treatment is carried out.
