Termites are the pest New Jersey homeowners worry about most, and the one where quotes vary the most. The good news is that the termites found here are the kind that can be treated without tenting the house. The less good news is that a full treatment still costs real money, and some of the quote depends on things like your well and your basement floor that you may not have thought about.
According to Rutgers Cooperative Extension fact sheet FS338, all naturally occurring termites in the northeastern U.S. are subterranean termites in the genus Reticulitermes. They nest in the soil, build mud tubes up foundations and feed on moist wood. Drywood termites, the ones that get whole houses tented in Florida and California, “usually do not cause damage to structures outside their natural distribution areas,” Rutgers says.
That matters for price. If a company proposes whole-house fumigation for a typical NJ infestation, ask why. Treatment here normally means a soil barrier, bait stations or both.
Rutgers also notes that swarmers usually appear on warm days between April and June, which is when most homeowners first notice a problem. Winged ants are often mistaken for termites; termites have wings of equal length, straight waists and beaded antennae.
Liquid soil treatment. A trench is dug around the foundation and filled with termiticide, and holes are drilled through slabs, patios or garage floors so the product can be injected underneath. Rutgers says a properly done soil treatment can be effective for more than five years and can eliminate a colony within one or two months when a non-repellent product such as fipronil or imidacloprid is used.
Baiting. Plastic stations are set in the ground about every 10 feet around the house. Termites find the bait, carry it back and the colony declines over a few months. Stations must be checked on a schedule and kept stocked.
Rutgers’ comparison is fair to both:
| Liquid | Bait | |
|---|---|---|
| Speed | Immediate protection | Months before termites find stations |
| Disruption | Drilling, trenching | Minimal |
| Product in soil | Large volume | Contained in stations |
| Upkeep | Little after treatment | Regular monitoring |
| Cost | “Often cheaper,” per Rutgers | Higher, plus yearly fee |

HomeGuide’s termite treatment cost guide (November 2025), based on national project data, gives these ranges:
| Item | Typical cost |
|---|---|
| Liquid soil treatment | $3 to $20 per linear foot; $500 to $2,000+ whole home |
| Bait system installed | $7 to $12 per linear foot; $1,000 to $2,500 whole home |
| Bait monitoring | $200 to $400 per year |
| Termite inspection | $0 to $250 |
| Termite bond or warranty | $500 to $2,000 |
| Tenting (rarely relevant in NJ) | $2,000 to $8,000 |
Sources disagree at the edges. One national termite company’s 2026 price page puts a liquid barrier at $1,000 to $3,200, higher than HomeGuide’s range. We have not found published NJ-only termite price data, so take these as national figures. NJ labour costs mean the middle to upper part of each range is the sensible expectation.
Linear footage is the main driver. A 30 by 40 foot house has about 140 feet of perimeter, so at $3 to $20 a foot a liquid treatment lands somewhere between roughly $420 and $2,800 before slab drilling and extras. That arithmetic is ours, not a quote.
New Jersey has its own termiticide restrictions in N.J.A.C. 7:30-10.4. The parts most likely to affect a homeowner:
The five-year retreatment rule is worth knowing. If a company wants to re-treat a house that was treated two years ago, ask for the evidence of new activity.
If you are buying or selling, the lender may want a wood destroying insect report on the NPMA-33 form. It records visible evidence of insects, damage and prior treatment. It is not a treatment and, as New Jersey Pest Authority notes, it does not estimate treatment or repair costs. Order the inspection; treat only if it finds active infestation.

Most NJ homes are treated for subterranean termites with a liquid soil barrier or a bait system. National cost data puts a whole-home liquid treatment at about $500 to $2,000 and a bait system at about $1,000 to $2,500 to install, plus roughly $200 to $400 a year for monitoring. Severe cases and large or complicated foundations cost more.
Almost never. Tenting with fumigant gas is mainly used for drywood termites. Rutgers notes that all naturally occurring termites in the northeastern U.S. are subterranean termites, which nest in soil, so treatment in New Jersey targets the soil and foundation instead.
Neither wins everywhere. Rutgers says liquid treatment is often cheaper and protects immediately but involves drilling and trenching and cannot be used near some wells. Baits are low-impact and leave nothing behind but can take months to work and need regular checks.
Sometimes, with restrictions. New Jersey rules change how liquid termiticide may be applied when a well or other water source is within 20 feet of the treatment site in sandy soil or 100 feet in other soils, and generally bar treating a structure with a well inside the foundation. Bait systems are the usual answer in those cases.
Many lenders, including FHA and VA loans, ask for a wood destroying insect inspection report on the NPMA-33 form. It records evidence of insects and damage. It is not a treatment, and it does not price repairs.
