The AhTown Guide to Pest Control in New Jersey

Which pests need a pro?

Is a monthly or quarterly plan worth it?

North Carolina State Extension says the need for monthly, quarterly or yearly service “is a matter of your personal preference.” The University of Nevada Extension warns against companies that apply pesticides on a fixed schedule whether or not you have a problem.

The New Jersey Department of Health recommends Integrated Pest Management (IPM): treat when pests pass a set threshold, and choose a company that offers both chemical and non-chemical options.

A plan can make sense if you have a recurring problem, like ants every spring or mice every fall, or if you'd rather not deal with it.

General pest control plans

Angi reports city averages ranging from $105 (Phoenix) to $255 (New York City).

What do New Jersey companies charge?

• A Moorestown pest control company publishes monthly plans of $45 to $55 for homes up to 2,000 sq ft, $50 to $60 for 2,000 to 3,000 sq ft, and $70 to $80 for 3,000 to 4,000 sq ft (February 2026).
• A cost site's Jersey City figures: initial visit $150 to $190, monthly $40 to $45, quarterly $100 to $300 (September 2026).

What do specific pests cost?

What makes the price go up?

• Square footage and how bad the problem is
• Rodent exclusion work (sealing entry points), which adds to the total
• After-hours or emergency visits, often $100 to $200 extra
• Long contracts with automatic renewal. Read the renewal terms before you sign

Quarterly vs. monthly vs. as needed

What is Integrated Pest Management (IPM)?

The EPA defines IPM as “an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices.” It has four steps:

1. Set a threshold for when action is needed.
2. Monitor and identify the pest.
3. Prevent it: seal gaps, fix moisture, remove food and shelter.
4. Control it, starting with the least risky methods.

New Jersey requires every indoor treatment notice to include a statement about IPM.

What should you ask about a plan?

• What triggers a treatment on each visit?
• Do you spray every visit, or only when you find activity?
• What happens if pests come back between visits?
• How does the plan renew, and how do I cancel?

How long after pest control can you go back inside?

Follow the product label. It's a violation of federal law to use a pesticide in a way that doesn't match its label. When the label gives no time, the National Pesticide Information Center (NPIC) says:

• Wait until the pesticide is totally dry, or longer.
• Open windows to air the space out before normal activity.
• For outdoor spraying, close windows and turn off the AC first.
• Put a blanket or play mat down where a baby crawls.

What does NJ require the company to tell you?

Before any indoor application, New Jersey requires the company to give you a Consumer Information Notice (N.J.A.C. 7:30-9.12) with:

• The brand and common names of the pesticides
• The safety precautions from the labels
• The company's contact information
• Phone numbers for NPIC, the NJ Poison Center and the NJ DEP pesticide complaint line
• A statement that full labels are available on request

For lawn applications, the company must post “Pesticide Treated Area” signs visible from the street for 72 hours. You can also ask in writing for a copy of the application record, which companies must keep for 3 years (5 for termite work).

Is pest control safe for cats and dogs?

NPIC says cats are more sensitive to permethrin than dogs or people. High-strength dog flea products with 45 to 65% permethrin can cause tremors, seizures and death in cats. Ask the technician which active ingredients they're using, and keep pets away until everything is dry.

What if you're pregnant?

NPIC's advice: have someone else do the application, leave the area, and give the home time to air out and dry before returning. Consider IPM methods that use fewer pesticides.

Who can you call with a question?

• National Pesticide Information Center: 1-800-858-7378
• Poison Help (reaches the NJ Poison Center): 1-800-222-1222

Season by season

Why does fall matter most for NJ homes?

Three pests try to get inside at once. Rutgers advises sealing windows and doors and taking out window air conditioners by mid-September to keep stink bugs out. Penn State says lady beetles gather on south and southwest walls around the beginning of October. Mice come in as temperatures drop.

How do you know you have mice?

• Droppings about 1/4 inch long
• A musky smell
• Greasy rub marks along walls
• Fresh gnaw marks and shredded insulation or paper

Rat signs are bigger: droppings about 3/4 inch long with blunt ends, burrows 2 to 3 inches wide outside, and gnaw marks you can see.

How do you keep mice out?

Check where pipes, wires and dryer vents enter the house, under doors, and around the garage door.

Traps or poison?

Traps have clear advantages: no poison in the house, you know when you've caught one, and you avoid the smell of a mouse dying inside a wall. Glue boards aren't recommended anywhere kids, pets or wildlife can reach them.

Since 2011, the EPA has required rodent poison sold to homeowners to come in a tamper-resistant bait station. Loose pellets are no longer allowed. The strongest poisons, second-generation anticoagulants like brodifacoum, can only be used by professionals.

How do you clean up after mice safely?

The CDC's guidance, to avoid breathing in viruses like hantavirus:

1. Open doors and windows for 30 minutes and leave the area.
2. Wear gloves. Don't sweep or vacuum droppings.
3. Spray droppings with 1.5 cups of bleach in a gallon of water. Let it soak 5 minutes.
4. Wipe up with paper towels and throw them out.

When should you call a pro?

• You're still catching mice after sealing the obvious gaps
• You see signs of rats
• You can't find how they're getting in

Mouse control averages about $350 nationally.

What are the signs of termites?

• Pencil-width mud tubes on foundation walls, piers or sill plates
• Swarms of winged insects indoors in spring, or piles of shed wings on windowsills
• Wood that sounds hollow or is packed with soil

A colony can hold 60,000 to 1 million termites, eating about 5 grams of wood a day.

Termite or carpenter ant?

Carpenter ants don't eat wood. They nest in wood that's wet or rotting, so finding them usually means a leak.

How are termites treated?

• Liquid soil treatment: a termiticide applied in a trench around the foundation. Non-repellent products like fipronil and imidacloprid are preferred for active infestations and last 5 or more years.
• Bait stations: placed about every 10 feet around the house and monitored for years.

Rutgers notes that repellent products don't reduce termite populations in the soil. Costs run $225 to $2,500.

NC State Extension offers a useful reminder: with termites, “a delay of even several weeks is really of no real consequence.” Don't sign under pressure. Get more than one inspection.

Do you need a termite inspection to buy a house in NJ?

For VA loans, yes: the VA requires wood-destroying insect information for the entire state of New Jersey. The standard report is the NPMA-33 form. Two NJ inspectors publish prices of $100 to $200 for it.

How do you prevent termites?

• Keep wood at least 6 inches above soil.
• Keep mulch and firewood away from the foundation.
• Fix leaks and drainage so soil by the house stays dry.

How common is Lyme disease in NJ?

New Jersey reported 6,258 Lyme disease cases in 2024. The state moved to lab-based reporting in 2022, so recent years aren't directly comparable to older ones.

Ticks you'll find in New Jersey:

• Blacklegged (deer) tick: spreads Lyme disease
• Lone star tick: an aggressive biter, linked to alpha-gal meat allergy
• American dog tick: widespread
• Asian longhorned tick: first identified in Hunterdon County in 2017

How do you make your yard less tick-friendly?

From the CDC:

• Remove leaf litter and clear tall grass and brush.
• Put a 3-foot barrier of wood chips or gravel between lawn and woods.
• Mow often.
• Keep swing sets and decks away from the yard's edges and trees.
• Stack wood neatly in a dry spot.
• Discourage deer with fencing.

Do tick yard sprays work?

They can reduce ticks. Guidance based on Rutgers research says a single, well-timed application in late May to early June can cut nymphs by more than 90%. The CDC still says you “should not rely on spraying” to reduce your risk. Keep doing tick checks. Yard spraying runs about $80 to $150 a visit.

How do you stop mosquitoes?

• Dump standing water weekly. NJ DEP says even a bottle cap of water can breed mosquitoes. An egg becomes an adult in 7 to 10 days.
• Empty flowerpot saucers and birdbaths, and clean gutters.
• Call your county. New Jersey has 21 county mosquito control agencies. Monmouth County, for example, takes requests for a courtesy inspection at 732-542-3630.

New Jersey averages about 22 human West Nile virus cases a year.

Is spotted lanternfly dangerous?

Not to people or pets. The NJ Department of Agriculture says it “does not harm humans or animals” and will not sting or bite. Penn State says it doesn't damage buildings. It feeds on more than 70 plant species, and its sticky waste (honeydew) grows black sooty mold on decks, cars and plants.

When do you see each stage?

What should you do?

1. Stomp adults and nymphs. NJ's campaign is “Stomp It Out.”
2. Destroy egg masses you can reach. Scrape them into a bag, or into rubbing alcohol or hand sanitizer.
3. Use circle traps. Rutgers calls them very effective. If you use sticky bands, cover them with chicken wire to protect birds.
4. Remove tree of heaven, its favorite host, if you can.

Do you need a pro?

Usually not. For valued trees under heavy attack, Rutgers suggests systemic insecticides when there are more than 500 lanternflies per tree. Licensed applicators typically apply those July to September. For light infestations, insecticidal soap or neem can work.

Are stink bugs harmful?

No. Rutgers says they won't bite people or pets. They release a bad smell when crushed or disturbed. The brown marmorated stink bug was first found in New Jersey in 1999, in Hunterdon County.

How do you keep them out?

• Caulk gaps around windows, doors, siding and utility lines. Penn State recommends silicone caulk.
• Cover attic and soffit vents with fine (#20) mesh.
• Repair or replace torn screens.
• Take out window AC units by mid-September.

What do you do with the ones inside?

Vacuum them up and throw out the bag. For lady beetles, Penn State suggests putting a nylon stocking inside the vacuum hose so you can empty them outside. Crushed lady beetles leave a yellow stain.

Do perimeter sprays work?

Somewhat. Rutgers says outdoor perimeter sprays “may reduce” numbers if applied when the bugs first show up on the house. Penn State notes sunlight breaks those sprays down in days to a couple of weeks, so timing in late September to early October matters. Sealing gaps does more.

What are the signs of bed bugs?

From the EPA:

• Rusty or reddish stains on sheets and mattresses
• Dark spots that bleed into fabric like a marker
• Eggs about 1 mm long, and pale yellow shed skins
• They hide in any crack as thin as a credit card

“Bites on the skin are a poor indicator,” the EPA says, because bites look like other insect bites.

Do bug bombs work on bed bugs?

No. Rutgers calls foggers “completely ineffective against bed bugs.” Most bed bugs in the field are also resistant to pyrethroids, the most common household insecticides.

Can you treat bed bugs yourself?

For small cases, the EPA suggests:

• Dry clothes and bedding on high heat.
• Steam seams and cracks at 130°F or more.
• Never try to heat your home with the thermostat, propane heaters or a fireplace.
• Monitor for at least a week and keep checking for a year.

Call a pro if that doesn't work or if the infestation is spread out.

How does heat treatment work?

Adult bed bugs die at 118°F and eggs at 122°F. Professionals heat rooms to about 135°F for 4 to 5 hours so hidden spots reach lethal temperatures (Virginia Tech Extension). Whole-home treatment averages about $2,500.

Is pest control the landlord's responsibility in NJ?

In buildings with three or more units, New Jersey rules (N.J.A.C. 5:10-10.2) make the owner responsible for getting rid of insects, rats or other pests when the infestation is in two or more units or in common areas. Owners must also arrange preventive pest control by qualified people at least once a year. Tenants are responsible for problems they have the power to prevent.

One- and two-unit rentals that the owner doesn't live in follow local ordinances. New Jersey has no specific bed bug law as of September 2026. Bills have been introduced but not passed. Complaints about multifamily buildings go to your local health department or the NJ DCA Bureau of Housing Inspection at 609-633-6219.

What licenses does a NJ pest control company need?

• Business license: no one may run a pesticide application business in NJ without a DEP license (N.J.A.C. 7:30-7.1). The license number must be on service vehicles, at least 3 inches high, on at least two sides.
• Certified applicator: each location must employ at least one certified commercial applicator in each type of work it does. Technicians without certification (registered operators) must work under a certified applicator's direct supervision.

To check a license or file a complaint, call the NJ DEP Pesticide Control Program at 609-984-6601.

What paperwork should you get?

• A Consumer Information Notice before any indoor treatment, listing the pesticides, label precautions and who to call with questions (N.J.A.C. 7:30-9.12).
• The application record, on written request. Companies must keep records for 3 years, or 5 for termite work.
• A written contract that states the price, what's covered, the warranty, and how it renews and cancels.

Red flags

The EPA warns about companies that:

• Knock on your door, especially targeting older homeowners
• Show you bugs they say came from a neighbor's house
• Quote a price per gallon or claim a “secret formula”
• Push you to sign right now because of “structural damage”
• Offer a discount on leftover materials
• Claim government endorsement
• Have no working phone number

If you buy from a door-to-door salesperson, the FTC's Cooling-Off Rule gives you 3 business days to cancel sales of $25 or more. Also watch for auto-renewing plans. Ask how renewal works and how to cancel before you sign.

Questions to ask before you hire

1. What's your NJ DEP business license number?
2. Who will do the work, and are they certified?
3. What exactly is the pest? How did you identify it?
4. Which products will you use? Can I see the labels?
5. How should I prepare, and how long should people and pets stay away?
6. Will you seal entry points, or only treat?
7. How many visits will it take?
8. What does the guarantee cover, and for how long?
9. How does the contract renew, and how do I cancel?
10. Do you carry liability insurance?
