Termite Treatment in Newark, NJ

Is It Termites? Swarmers, Tubes and Damaged Wood

The termite in this part of New Jersey is the Eastern subterranean termite (Reticulitermes flavipes). It nests in the soil, not in the house, and reaches wood through earthen tubes or direct contact. Formosan termites are not established here, and drywood termites are a southern and western problem — if anyone mentions either, ask what they saw.

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 Older Attached Housing

Subterranean termites need soil moisture, so they enter at or below grade. In Newark's older wood-frame two-families and row houses the entry points are predictable.

• Porches and stoops. Wooden porch posts set on or in the soil, and concrete stoops poured over fill against the house, are the most common entry we find. The fill under a stoop stays damp and hides the tubes.
• The sill plate and party wall. Where the timber sill sits close to grade, or where a shared wall runs into a damp cellar, termites can travel along it. In attached rows a colony does not respect the property line.
• Cellar floors and wood in contact with soil. Wooden posts on a dirt or cracked concrete floor, stair stringers resting on the slab, old form boards left in place, and storage timber on the ground.
• Leaks and poor drainage. A downspout discharging against the foundation, a failed gutter, or a rear yard that drains toward the house keeps the soil at the wall wet — exactly what a colony wants.
• Finished basements, where panelling hides tubes for years.

Heated cellars near boilers keep colonies active later into autumn and occasionally produce swarmers indoors in late winter.

Soil Treatment, Baiting and What Order to Do It In

On a narrow attached lot the method is usually decided by access. A side passage of bare soil can be trenched; a front stoop, a paved rear yard and a concrete cellar floor have to be drilled; a building where drilling is impractical may be better served by baiting.

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.

Correct the conditions at the same time. Pull soil and mulch back from the siding, redirect downspouts, get wood off the cellar floor, and fix leaks. Treatment addresses the termites; the conditions decide whether they come back.

Rentals, Shared Walls and Who Is Responsible

Termite damage is a structural condition, so in rented housing it is ordinarily the owner's responsibility, not the tenant's. If you rent and see swarmers or tubes, tell the landlord in writing, with the date and a photo, and keep a copy. Damage to joists, sills and porch structure is a property maintenance matter, and municipal code enforcement is the route if nothing is done. In registered multiple dwellings, the state Bureau of Housing Inspection is a second route.

For owners of attached buildings, the practical issue is the neighbour: a colony under a row ignores the property line, so treating one house while the next has active tubes on the shared foundation leaves a live source metres away. A written report is a better opening to that conversation than a guess.

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.

What a thorough termite estimate includes: where activity was found; the conducive conditions to correct; the method and why it suits this building; the product class; how often bait stations are checked, if baiting; and re-inspection and re-service terms in writing. Ask for the applicator's certification for termite work — in New Jersey termites and wood-destroying insects are their own certification category (7B).
