Wood-destroying insect control in New Jersey

Humid New Jersey summers and mild winters make the state a welcome home for wood-destroying insects. These pests work silently, creating structural damage that homeowners’ insurance will not cover. We have been handling wood-destroying insect control here in New Jersey since 1952, and the pattern we see is always the same: homeowners find out too late because nobody inspected early enough. 

Wood-destroying insects you’ll find in New Jersey

There are four groups responsible for nearly all wood damage in NJ homes.

Termites do the most damage. Eastern subterranean termites construct underground nests, sometimes hundreds of thousands strong, that reach your home through mud tubes along the foundation. Once inside, they consume the cellulose in wood framing, subflooring, and even wallpaper backing. The national cost of damage runs about $5 billion per year, and individual homeowners spend between $3,000 and $8,000 in repairs before someone realizes what is happening.

Carpenter ants don’t eat wood the way termites do; they excavate and hollow it out to build nesting galleries. They prefer damp, weakened wood around window frames, roof eaves, bathroom walls, and other moisture-prone areas. You might hear a dry scratching in the wall after the house goes quiet at night. A common sign is coarse sawdust collecting near baseboards or door frames, which is the frass they push out of the galleries they have chewed.

Powderpost beetles are harder to detect. Their larvae tunnel through hardwoods and softwoods for months, sometimes years, leaving fine powder inside the wood. You will know they are present when you spot pinhead-sized exit holes, usually 1/16 to 1/8 of an inch across, with powdery residue beneath them, or when a joist feels spongy under pressure.

Carpenter bees drill neat, round half-inch holes into exposed wood. Common targets include deck rails, fascia, porch columns and pergola beams. A single season of nesting holes may seem insignificant, but each subsequent generation reuses and extends the same tunnels, weakening the wood progressively. Woodpeckers compound the problem by digging out larvae from inside.

How to spot wood-destroying insect damage

We check for these signs on every inspection, and they are worth knowing as a homeowner, too:

• Mud tubes along foundation walls, piers, or basement window frames are a reliable termite indicator
• Wood that sounds hollow when you knock on it, even if the paint or finish looks fine
• Frass, small piles of sawdust-like material near baseboards, in basement corners, or around door frames
• Tiny exit holes in wood surfaces, sometimes with fine powder beneath them
• Translucent discarded wings near windows or exterior doors, usually after a warm-weather swarm
• Floorboards that buckle or sag, particularly in rooms with plumbing
• Faint tapping or rustling inside walls at night

If any of that sounds familiar, get it checked. The damage from wood-destroying insects builds quietly, but the repair costs are not quiet for long once a structural element fails.

Our wood-destroying insect control services

Arnold’s handles every stage of wood-destroying insect control: inspection, treatment, and the prevention work that keeps them from returning.

Inspection is the first step. We walk through the entire property, inside and outside, basement to roofline, checking for active infestations, evidence of previous damage, and conditions that promote future problems: moisture issues, wood-to-soil contact, and cracks in the foundation.

Treatment depends on what we find. Subterranean termites generally require liquid termiticide applied to the soil around the structure. Carpenter ant infestations need the colony to be located and treated at the source. Beetle and carpenter bee activity gets addressed with localized treatments matched to the species and severity.

Prevention is where the real long-term value lies. We walk homeowners through the practical steps: keeping crawl spaces ventilated, repairing leaks, storing firewood and mulch away from the foundation, and sealing entry points. Scheduled re-inspections catch new activity before it causes real damage.

Call (908) 276-8062 or contact us online to get an inspection on the books.

Why Arnold’s

We have been family-owned since 1952, more than seventy years based out of Cranford, serving homeowners across New Jersey. It has always been a straightforward business: diagnose accurately, communicate clearly, treat the problem properly, and avoid selling services people do not need. Customer reviews confirm that consistently.

Our technicians know the pest pressures specific to this state: subterranean termites in South Jersey’s sandy soils, carpenter ant colonies in the older wood-frame houses across Union and Essex counties, and powderpost beetles in hardwood flooring. We are a local company, not a national chain. The person who inspects your house has probably already done a few others on your street.

Frequently asked questions

Is a wood-destroying insect inspection worth it?

Definitely. These insects operate out of sight, and by the time you find damage, repairs can run into the thousands. An inspection catches the problem while treatment is still straightforward. If you are buying or selling property in New Jersey, a WDI inspection using the standard NPMA-33 report form is required for most transactions.

How do you get rid of wood-destroying insects?

It depends on the species. Subterranean termites typically need liquid termiticide applied to the soil around the foundation. Carpenter ants require locating and treating the colony directly. Powderpost beetles may need localized wood treatment or, in severe cases, fumigation. Correct identification is the first step, because a treatment that works on termites will not do much for beetles.

What are the signs of wood-destroying insect damage?

Mud tubes on foundations. Hollow-sounding wood. Sawdust piles or frass. Tiny exit holes in wood surfaces. Discarded wings near windows. Sagging or buckled floorboards. Any of those is reason enough to call a professional.

Wood-destroying insects are not going anywhere in New Jersey. The climate suits them too well. But the damage does not have to be something you deal with after the fact. Call Arnold’s Pest Control at (908) 276-8062 or contact us online to schedule an inspection. We have been at this since 1952, and we would rather find a problem early than explain a big repair bill later.
