Wasp nest, bed bugs, or a swarm right now?
- 1Do not spray a wasp or hornet nest yourself in daylight; agitated colonies sting in numbers and the nest usually survives.
- 2For bed bugs, stop moving mattresses and luggage between rooms right now: that is how one room becomes the whole house.
- 3For a termite swarm indoors, collect a few insects in a bag for identification and do not disturb the rest.
- 4Then call the companies above and ask specifically for same-day or next-day treatment availability.

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. These are typical U.S. ranges from our research, not Duncan-specific quotes; local prices vary with the job.
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 each company to confirm these in writing before work starts. One free request above reaches up to three of them at once.
Pests Duncan, SC companies actually treat
What a pest control company here gets called for, when it shows up, and which ones take an ongoing plan rather than a single visit. 5 of these 8 normally need recurring service.
Formosan termite control in Duncan, SC
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.
A far more aggressive subterranean termite with colonies in the millions.
What treatment involves. Whole-structure treatment. Spot treatment does not hold against this one.
Subterranean termite control in Duncan, SC
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.
The most destructive structural pest in the country, working out of sight from the soil.
What treatment involves. Liquid soil barrier or a monitored bait system, plus an annual inspection.
German cockroach control in Duncan, SC
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.
Breeds indoors fast and spreads between units, so a few become an infestation in weeks.
What treatment involves. Gel baiting with follow-up visits. One spray rarely finishes it.
Mice control in Duncan, SC
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.
Comes indoors as it cools, and chews wiring and insulation once established.
What treatment involves. Exclusion first, sealing entry points, then trapping and monitoring.
Bed bug treatment in Duncan, SC
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.
Arrives on luggage and furniture, not from poor housekeeping, and spreads room to room.
What treatment involves. Heat treatment or a multi-visit chemical program, with follow-up inspection.
Roof rat control in Duncan, SC
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.
Travels along roof lines and gets into attics, palms and citrus.
What treatment involves. Attic and roofline exclusion plus trapping. Baiting alone leaves the entry open.
Fire ant control in Duncan, SC
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.
Aggressive stinging mounds in lawns and near foundations, a real risk with kids and pets.
What treatment involves. Broadcast bait across the yard plus individual mound treatment.
Mosquito control in Duncan, SC
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.
Breeds in standing water within a few feet of where people are bitten.
What treatment involves. Source reduction plus barrier treatment on resting sites, repeated through the season.
Pest control plans in Duncan, SC, and what each one leaves out
Two quotes for pest control are rarely quoting the same thing. One covers ants and spiders four times a year, another includes rodents and free return visits, a third is a termite contract with a yearly renewal. Each service below has the one question that makes quotes comparable.
Recurring general pest plans
A technician treats the outside perimeter and the places pests get in, checks and refreshes bait stations where they are used, and treats inside only where there is activity. Most plans include return visits between scheduled services if covered pests come back.
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 and lot size, how many pests the plan covers, how often the visits are, and the first visit, which is usually heavier and priced higher than the routine ones that follow.
Ask before booking. Which pests does the plan cover, and which ones, such as termites, bed bugs, rodents or mosquitoes, cost extra?
The honest part. Most general plans leave out the expensive problems. Termites, bed bugs and rodent exclusion are usually separate contracts, so a low recurring price can be a plan for ants and spiders only. Read the exclusions before you compare prices.
Termite treatment, liquid or bait
A liquid treatment puts termiticide into the soil around and under the structure so termites cannot reach the wood. A bait system places monitored stations around the house that termites feed on and carry back to the colony. Many companies offer both, and some combine them.
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 structure's perimeter length, slab or crawlspace foundation, whether concrete has to be drilled, and for baits, the monitoring visits that continue after installation.
Ask before booking. Which method do you recommend for this house and why, and what does the warranty require me to keep paying each year?
The honest part. University of Florida research found baits eliminate the colonies that feed on them, while liquid barriers mainly keep termites out of the treated zone. A bait system only works while someone services it, so stations nobody checks protect nothing.
Termite warranties and renewals
After treatment most companies sell an annual renewal that keeps the warranty in force, with a yearly inspection. There are two kinds. Retreatment only means the company treats again if termites come back. Repair and retreatment also pays to fix new damage, up to a stated 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. Which kind of warranty it is, the repair limit, the size of the structure, and whether it transfers to a buyer if you sell.
Ask before booking. Is this retreatment only, or does it pay to repair new damage, and up to what amount?
The honest part. A retreatment-only warranty leaves every repair bill with you, and standard homeowners policies exclude damage from insects, termites included. Ask for the warranty document itself rather than the sales sheet, and check what voids it, such as missed renewals or new construction against the house.
Termite inspection for a home sale
A wood destroying insect inspection documents evidence of termites and other wood-destroying insects, existing damage, and conditions that invite them, usually on the standard NPMA-33 form. VA loans require one where termite infestation probability is moderate to heavy, and many buyers order one either way.
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 quickly the report is needed before closing.
Ask before booking. Will the report be on the form my lender accepts, and how long is it valid before closing?
The honest part. An inspection reports what is visible and reachable that day. It does not promise there are no termites behind finished walls, and a company that inspects and also sells the treatment has a reason to find something, so a second opinion on a large treatment quote is reasonable.
Rodent exclusion
Finding and sealing the gaps mice and rats use to get in, at the foundation, roof line, vents, garage doors and utility lines, then trapping what is already inside. Sealing is what ends the problem. Trapping alone only thins it out.
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. How many entry points there are, roof and attic access, the sealing materials, and the number of follow-up visits to check traps.
Ask before booking. Is sealing the entry points part of 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. If a quote has no sealing work in it, it is a monitoring service, not exclusion.
Mosquito and tick programs
A seasonal program that treats the shaded foliage where mosquitoes rest and the yard edges where ticks wait, and deals with standing water where mosquitoes breed. It is repeated through the season because each treatment wears off.
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 treatments in the season, and whether ticks are included.
Ask before booking. How many visits does the season include, and what do you do about standing water on my property?
The honest part. Barrier treatments reduce mosquitoes in the yard, they do not eliminate them, and mosquitoes from neighbouring yards keep arriving. Emptying standing water is the part that stops breeding, and you can do it yourself between visits.
One-time treatments
A single visit for a specific problem, such as a wasp nest, a pantry infestation or an isolated ant problem, without signing up for a 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 whether a follow-up visit is included.
Ask before booking. Is a follow-up visit included if the problem comes back within a few weeks?
The honest part. One visit fits some pests and not others. German cockroaches, bed bugs and most ant colonies take follow-up visits to finish, so a one-time price for those 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.

Six checks before you sign a pest control contract
Pest control is a licensed trade, so the first check is a real one with the state. The rest are about what the contract commits you to, which matters more than the price on the first page.
Check the applicator license
Commercial pesticide application is regulated in every state, and in this state applicator certification is handled by Clemson University's Department of Pesticide Regulation. Ask the company for its license number and the name of the certified applicator, then confirm both with the state.
Find the agency's contact details (NPIC)Get an inspection before a termite or rodent price
A recurring plan can be quoted from the size of the house, but termite and rodent work cannot. A price given on the phone before anyone has looked at the foundation, attic and entry points is a guess.
Compare the first visit and the recurring price separately
The first service is usually heavier and priced higher than the routine visits that follow. Two plans with the same quarterly price can cost very different amounts 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 any fee applies before you sign, not after the second visit.
Ask about free return visits
Most recurring plans send a technician back between scheduled services if covered pests return. Ask whether that is included and how soon they come out once you call.
Ask what product is being used
Ask for the product name, and follow the directions the technician gives you, which come from the product label, on when people and pets can go back into treated areas. The label, not a sales line, governs how a pesticide is used.

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.
