What does pest control cost?
National research range
$100 to $300 per visit
Quarterly recurring service runs about $100 to $200 per visit; one-time treatments and specialty work like termites cost more. U.S. research ranges, not Duncan quotes.
See the full Pest Control cost guideWhat moves the price
- One-time treatment versus a quarterly plan, which almost always costs less per visit.
- The pest itself: general ants and roaches sit at the low end, termites and bed bugs are their own category.
- Square footage and whether the crawlspace, attic, and yard perimeter are included.
- Follow-up visits: ask whether re-treatment inside the warranty window is free.
Ask companies to confirm these in writing. One request above reaches up to three.
Common pests in Duncan
What companies here get called for. 5 of these 8 usually need a recurring plan.
Formosan termites
Formosan termites often show up first as winged insects gathering around porch lights or window sills in the evening. Look for discarded wings on the floor and mud tubes on foundation walls. If you see swarmers, save a few for identification and call a pro.
What treatment involves. Whole-structure treatment. Spot treatment does not hold against this one.
Subterranean termites
Humid summers keep soil moist, which is just what subterranean termites need to stay active and tunnel toward your wood. Dry winters slow things down, but colonies underground carry on. Moisture near the foundation invites them, so keep gutters and downspouts directing water away.
What treatment involves. Liquid soil barrier or a monitored bait system, plus an annual inspection.
German cockroaches
German cockroaches hide in kitchens and bathrooms, behind appliances, inside cabinet hinges, and under sinks. Seeing them in daylight often means a crowded hiding spot. Small dark specks like pepper are another sign. Cut off crumbs and water first, then ask a pro about baiting.
What treatment involves. Gel baiting with follow-up visits. One spray rarely finishes it.
Mice
Dry winters in Duncan leave mice with little to eat or drink outdoors, so your pantry and garage start looking good. Even a gap the width of a pencil lets them in. Check around pipes and door sweeps before the nights turn cold.
What treatment involves. Exclusion first, sealing entry points, then trapping and monitoring.
Bed bugs
Bed bugs hide in mattress seams, headboards, and behind baseboards, so check there if you wake up with itchy bites in a line. Dark spots on sheets are another clue. Do not move bedding between rooms, and call a pro before trying DIY sprays.
What treatment involves. Heat treatment or a multi-visit chemical program, with follow-up inspection.
Roof rats
Roof rats travel along power lines, tree limbs, and rooflines, then slip into the attic through small gaps. You may hear scratching overhead at night or find gnawed vents. Trim branches back from the house and have a pro inspect the roofline.
What treatment involves. Attic and roofline exclusion plus trapping. Baiting alone leaves the entry open.
Fire ants
Fire ants build raised dirt mounds in sunny lawns, along driveways, and next to foundations. Walk the yard before kids and pets play, since disturbing a mound brings out stinging swarms. Keep your distance and have a pro treat it instead.
What treatment involves. Broadcast bait across the yard plus individual mound treatment.
Mosquitoes
Mosquitoes breed in any standing water, like clogged gutters, plant saucers, bird baths, and old tires. Dump and scrub those weekly, since larvae need only a few days. Shaded corners of the yard are where adults rest between bites.
What treatment involves. Source reduction plus barrier treatment on resting sites, repeated through the season.
Pest control plans and what they cover
Two pest control quotes rarely cover the same thing. Each service below has the one question that makes quotes comparable.
Recurring general pest plans
A technician treats the outside perimeter and entry points, refreshes bait stations, and treats inside only where pests are active. Most plans include free return visits.
Five of the eight pests common around Duncan, including German cockroaches, mice, roof rats, fire ants, and mosquitoes, usually call for repeat visits. A recurring plan fits that pattern better than a single spray. Check which of those pests the plan actually covers.
What moves the price. Home size, which pests are covered, how often visits come, and the heavier first visit.
Ask before booking. Which pests does the plan cover, and which ones, like termites or rodents, cost extra?
The honest part. Most general plans leave out the expensive problems. Termites, bed bugs and rodent exclusion are usually separate contracts, so read the exclusions before comparing prices.
Termite treatment, liquid or bait
A liquid treatment puts termiticide in the soil so termites cannot reach the wood. A bait system uses monitored stations that termites carry back to the colony.
Duncan's pest list includes two termite types, Formosan and subterranean, and the Formosan kind is far more aggressive. Ask each company which species it found and why it recommends liquid, bait, or both. Get the inspection report in writing before you sign.
What moves the price. The perimeter length, slab or crawlspace, any concrete drilling, and the bait monitoring visits after.
Ask before booking. Which method suits this house, and what does the warranty require me to pay each year?
The honest part. University of Florida research found baits eliminate the colonies that feed on them, while liquids mainly keep termites out. Bait stations nobody services protect nothing.
Termite warranties and renewals
An annual renewal keeps the warranty in force with a yearly inspection. Retreatment-only means treating again; repair-and-retreatment also pays for new damage up to a limit.
Ask to see the actual warranty document, not the sales sheet. Find out whether it covers retreatment only or also pays for repairs, and what voids it, such as a missed renewal. Compare renewal fees across quotes before you commit to a multi-year contract.
What moves the price. The warranty type, its repair limit, the size of the structure, and whether it transfers on sale.
Ask before booking. Is this retreatment only, or does it pay to repair new damage, and up to what amount?
The honest part. With retreatment only, every repair bill is yours, and homeowners policies exclude termite damage. Ask for the warranty document itself and what voids it.
Termite inspection for a home sale
A wood destroying insect inspection documents termite evidence, damage and conducive conditions, usually on the NPMA-33 form. VA loans require one in moderate to heavy termite areas.
If you are buying a home near Duncan, order the inspection early so any findings can be negotiated before closing. Ask for the standard form and a written report. If the same company quotes a big treatment, consider a second opinion.
What moves the price. House size, crawlspace and attic access, detached structures, and how fast the report is needed.
Ask before booking. Will the report be on the form my lender accepts, and how long does it stay valid?
The honest part. An inspection covers what is visible that day, not what sits behind finished walls. A company that also sells the treatment has a reason to find something.
Rodent exclusion
Finding and sealing the gaps mice and rats use at the foundation, roof line, vents and utility lines, then trapping what is inside. Sealing ends the problem.
Both mice and roof rats are on the Duncan list, and they enter differently. Mice use low gaps at the foundation, while roof rats come in at the roofline and vents. Ask a pro to inspect both levels and quote the sealing work.
What moves the price. The number of entry points, roof and attic access, sealing materials, and follow-up trap checks.
Ask before booking. Is sealing the entry points in this quote, and is the work guaranteed if they get back in?
The honest part. Bait boxes on a recurring plan manage rodents outside but do not stop them coming in. A quote without sealing work is monitoring, not exclusion.
Mosquito and tick programs
A seasonal program treats the shaded foliage where mosquitoes rest and the yard edges where ticks wait, and clears standing water. Each treatment wears off, so it repeats.
Mosquitoes are the main warm-season pest on the Duncan list, and a seasonal program treats resting spots on repeat since each treatment wears off. Ask how many visits are planned and empty standing water yourself between visits.
What moves the price. Yard size, how much dense planting there is, the number of visits, and whether ticks are included.
Ask before booking. How many visits does the season include, and what do you do about standing water here?
The honest part. Barrier treatments reduce mosquitoes but do not eliminate them, and neighbouring yards keep supplying more. Emptying standing water stops breeding, and you can do it yourself.
One-time treatments
A single visit for one specific problem, such as a wasp nest, a pantry infestation or an isolated ant trail, without signing up for a recurring plan.
A one-time visit suits a wasp nest or a single pantry problem near Duncan, with no contract to sign. Before you book, ask whether a return visit is included if the pests come back, and get the price in writing.
What moves the price. The pest, how established it is, how many rooms or nests are involved, and any follow-up.
Ask before booking. Is a follow-up visit included if the problem comes back within a few weeks?
The honest part. One visit suits some pests and not others. German cockroaches, bed bugs and most ant colonies need follow-ups, so a one-time price there usually means paying again.
What the Duncan climate means for pests
- The climate here is humid in summer and dry in winter, and pressure is seasonal, building through humid summers and pushing indoors as the weather turns.
Climate class from DOE Building America county zones.
Six checks before you sign a pest control contract
Pest control is a licensed trade, so start with the state license. The rest is what the contract commits you to.
Check the applicator license
Applicator certification here is handled by Clemson University's Department of Pesticide Regulation. Ask for the license number and the certified applicator's name, then confirm both.
Find the agency's contact details (NPIC)Get an inspection before a termite or rodent price
Plans can be quoted from house size, but termite and rodent work cannot. A phone price before anyone inspects the house is a guess.
Compare the first visit and the recurring price separately
The first service usually costs more than routine visits, so two equal quarterly prices can mean very different totals in the first year.
Read the contract length and how to cancel
Many plans renew automatically or carry a minimum term. Ask how you cancel and whether a fee applies before you sign, not after.
Ask about free return visits
Most plans send a technician back between services if covered pests return. Ask whether that is included and how soon they come.
Ask what product is being used
Ask for the product name, and follow the technician's directions from its label on when people and pets can go back into treated areas.

Frequently asked questions
How do I switch to a new pest control company in Duncan?
Start by reading your current contract for its term and cancellation clause, since some plans renew on their own. Ask the old company for its treatment records so the new one knows what was already used. If you have a termite warranty, check whether it survives a change of company before you cancel.
How are pest control prices set in Duncan?
Across the U.S., a pest control visit typically runs $100 to $300. A quarterly plan almost always costs less per visit than a one-time treatment. Ants and roaches sit at the low end, while termites and bed bugs are priced separately. Square footage and yard coverage also matter. One free request gets you exact prices from Duncan pros.
What time of year is best to start pest control?
Spring is the best time for a preventive perimeter treatment, because termite swarms and ants start then. Humid summers push mosquitoes, wasps, and roaches to their peak, and fire ants stay active from spring through fall. As nights cool, mice move indoors, so seal gaps before the first cold week.
Is a pest control plan in Duncan worth it?
A recurring plan usually means a technician treats your outside perimeter and entry points about every three months, with return visits if covered pests come back. Five of the eight pests common here, including German cockroaches, mice, and fire ants, usually need that kind of plan. Termites and bed bugs are often excluded, so read the fine print.
How can I tell if an exterminator is legitimate?
Ask the company for its pesticide applicator license number and the name of the certified applicator who holds it. Then confirm both with the state regulator linked further down this page. Also ask for a general liability insurance certificate. A reputable company will send proof without any pushback.
How does the quote request work in Duncan?
You fill out one short request with no account needed. At most three pros see it, and your request is never resold. Each of them can reply with availability and a price. You then compare the replies and choose who to hire, or skip them all. Nothing is required of you.
