Pest control and termites in the Triangle: a homeowner's guide

This guide covers what termite treatment and pest control cost around Raleigh, Durham, Cary and Chapel Hill, how North Carolina licenses the people who do the work, and the rules a termite contract and a home-sale termite report must follow. It also covers the local pests a homeowner here is most likely to meet: subterranean termites, fire ants, tiger mosquitoes and lone star ticks.

What pest control and termite work costs in the Triangle

These are guide figures from cost sites and NC State Extension, and most of them are national rather than local. Use them to tell whether a quote is in the usual range, then get written quotes from two or three companies for your own house.

Termite treatment

Angi puts the national average for termite treatment at $621, with most homeowners paying $263 to $1,033, based on 7,800 projects (Angi, termites). HomeGuide puts a liquid soil treatment for the whole house at $500 to $2,000, or more for a severe infestation (HomeGuide). It puts a bait system at $1,000 to $2,500, plus $200 to $400 a year for monitoring (HomeGuide).

NC State Extension puts the yearly renewal for a house treated with a liquid termiticide at $85 to $200 (NC State Extension, termites). Some contracts later call for a "booster" retreatment, which NC State says often costs $600 to $1,200, or for a renewal fee that may be 25% to 50% higher instead (NC State Extension, termites).

HomeGuide puts a "termite bond", covering annual inspections and treatment if termites are found, at $500 to $2,000, without saying whether that is per year (HomeGuide). If that is a yearly fee, it is far above NC State's renewal range, so ask exactly what a yearly fee buys: an inspection, retreatment, or repair of damage. Cost sites use "termite bond" loosely for a service plan; in the state rules a bond is a written guarantee from a bonding, surety or insurance company that the contract will be carried out (02 NCAC 34 .0901). A company in North Carolina that says it is bonded must have that bond in force (02 NCAC 34 .0901).

What drives the price

HomeGuide lists the size of the house, the foundation, the treatment method, how bad the infestation is, the inspection, and whether you buy a termite bond (HomeGuide). A house on a slab needs less work than one with a crawl space or basement (HomeGuide). A liquid treatment can take several hundred gallons of diluted insecticide, which is why the EPA lists a per-gallon price as a warning sign (EPA).

General pest control plans

Angi's Raleigh cost page puts pest control at $106 on average, with a range of $77 to $155 (Angi, Raleigh). Its table gives these ranges for Raleigh (Angi, Raleigh):

Mosquito and wildlife work

For mosquito service, Angi's national average is $350 per treatment or season, and most homeowners spend $200 to $550 (Angi, mosquitoes). Its table puts a barrier spray at $70 to $150 per treatment, and a misting system at $1,200 to $2,500 to install plus $400 to $700 a year (Angi, mosquitoes).

Angi's national average for wildlife removal is $402, and most homeowners pay $198 to $636 (Angi, wildlife). Its table lists bats at $230 to $700, squirrels at $200 to $600 and raccoons at $400 to $600 (Angi, wildlife).

Licenses: who may do this work in North Carolina

North Carolina's Structural Pest Control Act splits the work into three license phases: P for household pests, W for wood-destroying organisms such as termites, and F for fumigation (G.S. 106, Art. 4C). A licensee must be licensed in each phase they work in; one license can cover several phases (G.S. 106, Art. 4C). Termite inspections fall under the W phase, and so does the Wood-Destroying Insect Report used when a house is sold (NCDA&CS licensing).

To get a license, a person must already be a certified applicator in that phase, have two years of documented experience in it, and pass the license exam (NCDA&CS licensing). Licenses are issued only to individual people, not to companies (NCDA&CS licensing; G.S. 106, Art. 4C). Technicians, salespeople and estimators carry a state ID card, and they must show it to the person they are working for on request (G.S. 106, Art. 4C).

A licensee must carry general liability insurance of at least $100,000 for property damage and $300,000 for bodily injury per occurrence, or a $300,000 combined single limit (02 NCAC 34 .0902). The license lapses if that policy is cancelled or falls below those limits (02 NCAC 34 .0902).

How to check a license

The NC Department of Agriculture and Consumer Services (NCDA&CS) has a free public license search (NCDA&CS license search). It covers structural licenses (type 021), certified applicators (081) and registered technicians (082), and you search by last name and county (NCDA&CS license search). Mosquito and lawn care companies that hold a pesticide license instead are listed under the "Commercial" type (NCDA&CS license search).

Service trucks must show the license number and phases, or the company name, on both sides in letters at least two inches high (02 NCAC 34 .0320). The letters after the license number show the phases: P for household pests, W for termites and other wood-destroying pests, F for fumigation (02 NCAC 34 .0321). A company licensed in several phases shows several letters, such as PW (02 NCAC 34 .0321).

Wildlife is a separate system

Removing nuisance wildlife runs through depredation permits from the NC Wildlife Resources Commission (NC Wildlife Commission). Wildlife Control Agents, trained and certified by the Commission, can issue those permits to residents who have wildlife damage (NC Wildlife Commission). The permits are free, but the agents are not Commission officials and may charge for their time and removal work (NCWRC depredation). No state ruling turned up for this guide on whether a company that removes animals from an attic also needs a structural pest control license, so ask a wildlife company which credentials it holds.

Permits, contracts and termite reports

The research for this guide found no town permit for pest control or termite treatment in Raleigh, Durham, Cary or Chapel Hill. The rules that protect you come from the state instead: the written contract a termite company must give you, the WDIR-100 report used in home sales, and a free state complaint process. A state permit does apply to moving plants and sod out of the fire ant quarantine (NCDA&CS, January 2026), covered under Triangle conditions below.

A termite contract must be in writing

Before any termite treatment starts, the company must give you a written proposal describing the work, and once you accept it in writing it becomes the contract (02 NCAC 34 .0601). If you have not accepted the proposal in writing, the company must still offer you a written agreement within 14 days of starting the work (02 NCAC 34 .0601).

For an existing home, the agreement must list, among other things (02 NCAC 34 .0605):

• the inspection date and the inspector's full name;
• the license number and phases;
• a diagram of the foundation showing any evidence of termites, whether the infestation is active or inactive, damaged timbers, and the areas treated and not treated;
• the period the agreement covers;
• whether there will be reinspections, how often, and what renewal costs;
• the conditions under which retreatments will be made;
• the total price;
• whether the agreement or warranty transfers to a later owner, and on what terms.

The company must also say in writing whether it will pay to repair or replace damaged wood it saw, and it must list any part of the house it did not inspect, with the reason (02 NCAC 34 .0504). If it will skip any of the state's minimum treatment steps, such as drilling a finished slab, each skipped step must be explained in writing on the state waiver form before work starts (02 NCAC 34 .0603). The form itself tells owners not to sign it if they have questions about the treatment, and never to sign it blank (NCDA&CS waiver form).

Warranties, renewals and bonds

NCDA&CS describes three kinds of termite agreement: retreatment only, retreatment plus repair of damage up to a stated amount, and no warranty at all (NCDA&CS warranty guide). Retreatment only is the most common kind; it does not pay to repair termite damage, and most agreements run for one year after the first treatment (NCDA&CS warranty guide).

An annual contract pays for a yearly inspection, not a yearly treatment (NC State Extension, termites). NC State Extension says treating every year without signs of termites is illegal under most termiticide labels (NC State Extension, termites), and federal law makes it a violation to use a pesticide in a way its label does not allow (EPA, labels). You, or anyone living in the house, can ask for the name, active ingredient, formulation and EPA registration number of any pesticide applied, and the company must tell you (02 NCAC 34 .0404).

Think before switching companies if you have a repair warranty. NC State Extension warns that a new company's repair warranty will again exclude current or old damage, and that a contract on a resale home that had no contract will likely exclude existing damage (NC State Extension, termites).

North Carolina does not require termite bonds (02 NCAC 34 .0901). A company that advertises itself as bonded must actually have the bond, must tell each customer in writing whether their contract is covered by it, and, where it is, must copy the bond's guarantees into the contract word for word (02 NCAC 34 .0901; 02 NCAC 34 .0605).

For a new house treated during construction, any warranty must be a one-year retreatment warranty that transfers to a new owner, and the owner must be offered renewal for four more years in a row (02 NCAC 34 .0605). Missing one year's renewal ends that right (02 NCAC 34 .0605).

The WDIR-100 when you buy or sell

Any written statement about termites or other wood-destroying insects in a house for sale must be on the state's Wood-Destroying Insect Information Report, form WDIR-100, and it may only be issued after an actual inspection (02 NCAC 34 .0602). Only a licensee, or someone who works for one, may issue it, and NCDA&CS says it is required on almost every home sold (NCDA&CS WDIR guide).

The report records what was visible on the day of the inspection; it is not a warranty that the house is free of termites (NCDA&CS WDIR guide). The inspector must report conditions that invite termites, including at least wood touching the soil, cellulose debris under the house, and wood with a moisture content of 20% or more (NCDA&CS WDIR guide). NCDA&CS warns buyers and lenders that most North Carolina homes more than 10 to 15 years old will show some evidence of wood-destroying insects, and that a "clear" report should not be expected (NCDA&CS WDIR guide).

If the inspector finds termite evidence and no sign the house was ever treated, the house must be treated before a WDIR-100 can say it is free of termites or that an old infestation is inactive (02 NCAC 34 .0602). When a treatment is done along with the report, the contract and any warranty must be attached to it (02 NCAC 34 .0602).

Filing a complaint with the state

If you think termite or pest work was done wrong, you can ask the NCDA&CS Structural Pest Control Division for an inspection on its request form, online or by mail (NCDA&CS complaint guide). The form asks for your name, address and phone and the company's name and location, and you should have copies of every contract ready (NCDA&CS complaint guide). The state inspection is free, and the inspector should contact you within one to two business days of receiving your complaint from the Division's Raleigh office (NCDA&CS complaint guide).

Problems found must be corrected within 30 days of the Division notifying the company in writing (NCDA&CS complaint guide). The Structural Pest Control Committee can fine a company up to $2,000 per violation and can suspend or revoke licenses (NCDA&CS complaint guide; G.S. 106, Art. 4C). The state does not pay homeowners for damage; getting money back may take a private lawsuit (NCDA&CS complaint guide). Complaints about home repair scams in general go to the NC Attorney General's office (NCDOJ, repair scams).

Triangle conditions that matter

Termites

Subterranean termites are by far the most common termites in North Carolina (NCDA&CS, termites). The imported Formosan subterranean termite has been found in a few places in the state but is not widespread (NCDA&CS, termites). The newest NC State source found for this guide that names a place, a 2016 training newsletter, puts Formosan termites in Rutherford County in western North Carolina, not the Triangle (NC State, 2016 newsletter).

Native subterranean termites swarm from late winter into September or October, usually on warm days after rain (NC State Extension, termites). Swarmers outdoors near stumps or landscape timbers do not mean your house is infested, but a swarm indoors usually means an infestation somewhere in the house (NC State Extension, termites). If you find termites, you have time to compare two or three inspections: NC State says a few days or even a few weeks will make no real difference to the damage, and NCDA&CS says not to be rushed into a termite control program (NC State Extension, termites; NCDA&CS warranty guide). If you are building, the North Carolina Building Code requires some form of termite protection on every new home (NC State Extension, termites).

Carpenter ants

Carpenter ants tunnel through wood without eating it and prefer wood with a moisture content of 15% or more, so they often point to a moisture problem (NC State Extension, carpenter ants). From early spring, workers foraging for water around sinks, dishwashers and showers are a warning sign (NC State Extension, carpenter ants).

Asian tiger mosquitoes

The common backyard mosquito here is the Asian tiger mosquito, which breeds in containers and flies only 100 to 300 yards, so it can reach your yard from standing water elsewhere in the neighborhood (NC State Entomology). NC health officials advise emptying standing water from flowerpots, gutters, buckets, pool covers, pet water dishes, old tires and birdbaths at least once a week (NCDHHS).

NC State researchers found Wake County tiger mosquitoes developing resistance to pyrethroids, a class of insecticides commonly used in backyard mosquito sprays (NC State, mosquito resistance). By 2023, resistance mutations showed up in 84% of sampled residential blocks (NC State, mosquito resistance). Before you pay for a spray plan, ask which insecticide it uses and what the company does about breeding sites.

Lone star ticks

The lone star tick is the tick most likely to bite people in North Carolina (NC Tick Guide). An NC State entomologist says that in the Piedmont it often makes up about 90% or more of the ticks his team catches in field sampling, and around 65% of the ticks people find on themselves or their pets (NC State News). It is linked to alpha-gal syndrome, an allergy to red meat (NC State News). State public health officials say most tick-borne diseases occur between May and September (NC DPH).

Fire ants and the quarantine permit

All of Wake, Durham, Orange, Chatham and Johnston counties are inside the state's imported fire ant quarantine, according to the 2024 county list (NCDA&CS fire ant list). The quarantine reached 81 counties in January 2026 (NCDA&CS, January 2026). Moving sod, soil, nursery stock, hay or straw from these counties into or through areas without fire ants needs a permit first (NCDA&CS fire ant list; NCDA&CS, January 2026).

Rodents and bed bugs

Mice can get in through gaps of a quarter inch, and adult rats through gaps of half an inch, so sealing gaps is a necessary step in keeping them out (NC State Extension, mice; NC State Extension, rats). The two rats that invade buildings are the Norway rat and the roof rat (NC State Extension, rats). Bed bugs usually arrive as hitchhikers, in luggage from hotels or rentals or in second-hand furniture (NC State Extension, bed bugs).

Hiring: questions to ask and red flags

The EPA says most pest problems can wait a few days while you choose a company, and advises getting several estimates (EPA). If no termites were found, a preventive treatment is your choice: NC State Extension says a company may suggest one but cannot tell you that you need it (NC State Extension, termites).

Questions to ask

• What is your license number, and which phases does it cover? Then look it up in the NCDA&CS license search (NCDA&CS license search).
• May I see the technician's state ID card? It must be shown on request (G.S. 106, Art. 4C).
• Is this agreement retreatment only, or does it also pay for repairs, and up to what amount (NCDA&CS warranty guide)?
• How often will you reinspect, what will renewal cost, and does the agreement transfer if I sell (02 NCAC 34 .0605)?
• Will you skip any of the state's minimum treatment steps? Each one must be explained on the waiver form before work starts (02 NCAC 34 .0603).
• Is this contract covered by a bond? A company that advertises a bond must tell you in writing (02 NCAC 34 .0605).
• What product will you use, and what is its EPA registration number (02 NCAC 34 .0404)?
• Does the plan renew automatically, and how do I cancel?

On that last question: in North Carolina, a contract that renews on its own must say so clearly and explain how to cancel (G.S. 75-41). Where the renewal period is longer than 60 days, the company must send written notice 15 to 45 days before the renewal date, and a renewal clause that breaks these rules is void (G.S. 75-41).

Red flags

• Pressure to sign now because the house is unsound and may collapse (EPA).
• A discount on "leftover material" from a previous job, or a seller going door to door (EPA).
• A claim that a government agency requires or endorses the treatment. Government agencies do not endorse any service company or pesticide product (EPA), and North Carolina bars companies from claiming they do (02 NCAC 34 .0904).
• Being told you have a pest without being shown the evidence. North Carolina bars companies from saying a pest is present unless visible evidence exists (02 NCAC 34 .0904).
• A termite quote priced per gallon (EPA).
• Someone who turns up offering to fix a problem you did not know about, or who wants cash. The NC Attorney General says to use a check or credit card instead (NCDOJ, repair scams).
• A wildlife quote that promises to relocate a raccoon, skunk, fox or groundhog. Relocating these animals is illegal in North Carolina (NCWRC FAQ), even though Angi's national cost guide describes raccoon removal as including relocation (Angi, wildlife).

If you signed at your kitchen table

Under the FTC's Cooling-Off Rule, most sales of $25 or more made at your home can be cancelled until midnight of the third business day after the sale, and the seller must tell you about that right in writing (16 CFR 429). Saturdays count as business days; Sundays and federal holidays do not (16 CFR 429).

North Carolina's own three-day right to cancel a home sale, in G.S. 25A-39, covers sales made on credit (G.S. 25A-38; G.S. 25A-39). The NC Attorney General describes the state right more broadly, as covering contracts signed anywhere other than the seller's normal place of business, including your home (NCDOJ, repair scams). The two sources differ on scope, so act within the three business days either way.
