Wasp nest, bed bugs, or a swarm right now?

- 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 Irmo-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 Irmo, 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 Irmo, SC
Watch for discarded wings on windowsills and near lights after an evening swarm, and for mud tubes along foundation walls. If you see either, bag a few insects for identification, leave the rest alone, and ask the company for a whole-structure inspection.
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 Irmo, SC
Irmo's humid summers keep soil moist, which is exactly what subterranean termites want, and they feed quietly through the warm months. Dry winters slow them down but do not remove them, so the yearly inspection matters even when nothing looks wrong.
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 Irmo, SC
Check kitchens and bathrooms first, especially behind the fridge, under sinks and inside appliance motors. Small dark specks like pepper flakes and sightings after lights go on are common giveaways. Clean up crumbs and fix drips while you wait for a visit.
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 Irmo, SC
Irmo's dry winters and cool nights send mice looking for warm, sheltered spots inside, so they head for garages, pantries and wall voids. Droppings, gnawed packaging and scratching at night usually show up first once the temperature drops.
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 Irmo, SC
Look for tiny rust-colored spots on sheets, shed skins along mattress seams and bites in a line on skin. Check headboards and luggage after trips. Do not move bedding between rooms, since that spreads them, and call a pro quickly.
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 Irmo, SC
Listen for scratching in the attic after dark and look for greasy rub marks along rafters, gnawed wiring or droppings near vents. Trim tree limbs that touch the roof, since roof rats use branches as a bridge into your home.
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 Irmo, SC
Look for dome-shaped mounds in sunny lawn spots, along driveways and beside foundations. Never poke a mound, since the colony swarms up the leg fast. Keep kids and pets away from any mound you spot and point it out to the technician.
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 Irmo, SC
Walk your yard and tip out anything holding water, such as plant saucers, buckets, gutters and old tires, since mosquitoes breed within a few feet of where you get bitten. Shady spots by the patio and dense shrubs are where they rest.
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 Irmo, 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 in Irmo, German cockroaches, mice, roof rats, fire ants and mosquitoes, usually need repeat visits. That makes a recurring plan the better fit than one-off sprays. Read the exclusions closely, because termites and rodent sealing are often separate.
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.
Irmo's list includes both Formosan and subterranean termites, and Formosan colonies do not respond to spot treatment. Ask each company which method it recommends for your house and why, and whether the bait stations will actually be checked on a schedule.
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 for the warranty document itself, not the sales sheet, and compare quotes on what the renewal covers, not just the fee. Check what voids it, such as a missed renewal or new construction against the house, and whether repairs are included.
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 or selling in Irmo, book the inspection early enough to leave time for treatment before closing. Ask for the written report on the standard form, and consider a second opinion if the same company is also quoting a large treatment.
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.
Irmo's list covers both mice and roof rats, and they get in differently. Mice use foundation gaps and garage doors, while roof rats come in along the roofline. A good quote names every entry point it plans to seal, not just trapping.
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 one warm-season pest on Irmo's list that a seasonal program is built around. Expect repeat visits, since each treatment wears off, and plan to dump standing water yourself between visits because that is what stops breeding.
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.
If you are in Irmo with a wasp nest or a single ant trail, a one-time visit may be all you need. Ask what the price includes and whether a callback is free, so a small problem does not turn into a second bill.
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 Irmo 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 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
Which pests show up first in spring here?
Termite swarms and ant activity kick off in spring, so those are the first pests you will notice. Fire ants start building mounds in the same stretch, and mosquitoes follow once Irmo's humid summer settles in. Spring is also the best month for a preventive perimeter treatment, before the summer rush.
Is one pest control treatment enough?
It depends on the pest. Five of the eight pests common here, including German cockroaches, mice, roof rats, fire ants and mosquitoes, usually need a recurring plan. A one-time treatment fits a wasp nest or an isolated ant problem, but cockroaches and bed bugs take follow-up visits, so a single price often means paying twice.
Can I hear back the same day in Irmo?
Sometimes, but it depends on the company. Of the 10 companies listed, 3 publish weekend hours on Google, so most keep weekday schedules. One free quote request reaches up to 3 of them at once. Mention the pest and ask for same-day or next-day availability, especially for wasps, bed bugs or a termite swarm.
What does a termite warranty actually cover?
It depends on which kind you get. A retreatment-only warranty means the company treats again if termites return, but you pay for repairs. A repair and retreatment warranty also covers new damage up to a stated limit. Standard homeowners policies exclude insect damage, so ask for the actual warranty document.
How can I tell if an exterminator is legitimate?
Ask for the company's license number and the name of the certified applicator, then confirm both with the state pesticide regulator linked further down this page. Also ask whether the technicians who visit your home are certified, not just the owner, and request a certificate of general liability insurance.
Is pest control expensive in Irmo?
Typical U.S. pricing runs about $100 to $300 per visit. A quarterly plan almost always costs less per visit than a one-time treatment, and termites and bed bugs are priced separately from ants and roaches. Square footage and crawlspace or attic coverage also move the number. One free request gets you exact Irmo prices.
