Figures cover the St. Louis metro area. Most companies price by home size and pest, so a larger house pays more for the same treatment.
Pest control prices across St. Louis
Home size moves the price more than the address. Apartments and row houses in Downtown, Grand Center & the Grove usually cost less per visit; bigger homes and yards in areas like St. Charles, Clayton & the suburbs cost a little more.
Downtown, Grand Center & the Grove
- One-time visit
- $250–$500 per visit
- Plan visit
- $95–$300 / quarterly plan visit
Dense blocks with older buildings. Smaller homes keep one-time visits near the low end, but roach and rodent jobs here often need two or three trips.
North St. Louis
- One-time visit
- $260–$510 per visit
- Plan visit
- $95–$300 / quarterly plan visit
Lots of remodels and older homes. If walls are open, it's a cheap time to treat for termites or seal mouse gaps.
South City & Dutchtown
- One-time visit
- $260–$530 per visit
- Plan visit
- $100–$300 / quarterly plan visit
Close to the city typical. Mid-century homes on crawlspaces are worth a termite check every year or two.
St. Charles, Clayton & the suburbs
- One-time visit
- $290–$590 per visit
- Plan visit
- $100–$330 / quarterly plan visit
Newer homes on slabs still get termites, and lawns bring ants and fleas. Quarterly plans are the usual buy here.
Real-world pest control costs in St. Louis
Here's what common pest control jobs cost in St. Louis in 2026, labor and products included.
Ants in the kitchen: one visit
A tech finds where they come in, treats inside and sprays a barrier outside. Most ant jobs in St. Louis run $100–$410; a full inside-and-out visit for every common bug is $150–$570.
German roaches in an apartment
German roaches are hard to wipe out, and most roach jobs take two to eight weeks to fully work. Budget $100–$610 for the program. If the building has them too, ask the landlord to treat the units next door.
Mice in the garage: trap, then seal
Trapping or baiting with follow-ups runs $150–$660, and sealing the gaps they use another $210–$1,500. Skip the sealing and you'll likely pay for trapping again next fall.
Termites found during a home sale
The termite (WDI) report costs $50–$230. If it finds live subterranean termites, a liquid barrier around the house runs $820–$3,050. Ask who pays: buyers often negotiate it into the sale.
Year-round plan: first visit plus quarterly
A $150–$300 first visit, then three quarterly visits at $100–$300 each, comes to $450–$1,200 for the first year. Most plans include free return visits if bugs come back between services.
How much does pest control cost in St. Louis?

What moves a pest control quote in St. Louis:
- The pest: ants and spiders are cheap; bed bugs run $310–$810 a room and termites $820–$3,050 for a barrier.
- Home size: most companies price by square footage; a 3,000 sq ft home runs about $200–$780 for one visit.
- How bad it is: heavy roach or rodent problems need follow-up visits, and each one adds to the bill.
- One visit or a plan: plan visits run $100–$300 quarterly or $40–$75 monthly, against $310 for a one-off.
- Sealing and repairs: closing mouse gaps adds $210–$1,500; termite damage is a separate repair bill.

Pest control cost in St. Louis by home size
A one-time visit is about $120–$470 for a 1,000 sq ft home, $150–$570 for 1,500–2,000 sq ft, and $200–$780 for 3,000 sq ft in St. Louis.
Worked example: a 2,000 sq ft St. Louis home on a quarterly plan pays $210 for the first visit and $150 for each of three more visits, about $660 for the first year. Adding a mosquito season of five yard visits at $140 adds $700.
Bigger homes take longer to treat, so most companies step the price up with square footage. Termite work is priced by the length of the foundation instead: a liquid barrier around a typical house runs $820–$3,050.
St. Louis pest control prices by pest
| Pest | Cost | Best for |
|---|---|---|
| Ants | $100–$410 per job | Kitchen trails and nests near the house; carpenter ants may cost more |
| Cockroaches | $100–$610 per job | German roaches indoors are the hardest to clear; bigger outdoor roaches need a barrier |
| Spiders | $100–$300 per job | Webs around eaves, garages and basements |
| Fleas | $100–$410 per job | Pet homes; treat the pets with your vet at the same time |
| Bed bugs | $310–$810 a room; $1,550–$6,100 whole home | Heat takes about 6–9 hours for a home; chemical jobs need 2–4 visits |
| Mice and rats | $150–$660 plus $210–$1,500 to seal | Trapping or bait first, then sealing the gaps they use |
| Raccoons, squirrels and opossums | $210–$610 per job | Animals in attics, crawlspaces and chimneys |
| Wasps, hornets and yellow jackets | $130–$810 per nest | Nests near doors, eaves or inside walls |
| Termites (subterranean) | $820–$3,050 liquid; $1,000–$2,550 bait | Mud tubes on the foundation, soft wood near the ground |
| Termites (drywood) | $260–$1,200 spot; $1,550–$5,050 tenting | Small pellets near windows and wood trim, common in warm coastal areas |
One visit vs a year of service in St. Louis
A one-time visit at $310 sounds cheaper than a plan, but if bugs come back you pay it again. A quarterly plan in St. Louis costs about $660 for the first year ($210 to start, then three visits at $150), and after that about $600 a year, with free return visits between services.
Monthly service runs $40–$75 a visit, or $480–$900 a year. It makes sense for heavy roach problems or apartments; for most houses, quarterly is enough.
What's included in a St. Louis pest control quote (and what costs extra)
A general pest visit covers an inspection, treatment inside and out for common bugs like ants, roaches and spiders, and usually free return visits if they come back before the next service. It usually leaves out:
- Termites: a separate inspection ($75–$300 where it isn't free) and treatment from $260
- Bed bugs: $310–$810 for one room, $1,550–$6,100 for a whole-home heat job
- Sealing and wildlife: $210–$1,500 to seal mouse gaps, $210–$610 for a raccoon or squirrel
- Mosquitoes: $75–$200 a yard visit, often sold as a season of visits
Ask for the products used, the re-service promise and the cancel terms in writing.
The pest
Ants, spiders and roaches are quick general treatments ($100–$410 for ants). Bed bugs ($310–$810 a room) and termites ($820–$3,050 for a barrier) take special products, more time and often more visits.
Home size
Most companies price by square footage. One visit runs about $120–$470 for a 1,000 sq ft home and $200–$780 for 3,000 sq ft in St. Louis.
How bad it is
A few ants is one visit. A heavy roach, flea or rodent problem needs follow-ups, and companies price the whole program up front or charge per extra visit.
One visit or a plan
Plans cost less per visit: $100–$300 each quarter or $40–$75 a month, after a $150–$300 first visit, against $150–$570 for a one-off.
Termite type
Subterranean termites live in the soil and are treated with a liquid barrier or bait stations. Drywood termites live in the wood itself and often need tent fumigation ($1,550–$5,050) or spot work. Formosan termites, found across Florida and the Gulf Coast, Hawaii and Southern California, build colonies of several million.
Sealing and wildlife
Rodents and wildlife come back unless their way in is closed. Sealing gaps runs $210–$1,500, and removing a raccoon, squirrel or opossum $210–$610.
Local labor
Pest control workers in the St. Louis metro earn a median of about $21.75 an hour (BLS, May 2025), against $21.75 nationally. A typical one-time visit here is $310, above the $300 national typical.
- Get a free inspection first.Most big companies inspect for free when it isn't for a home sale. Get the pest named and the plan in writing before you pay for anything.
- Fix what lets them in.Seal gaps, fix leaks and move firewood and mulch away from the house. Sealing mouse gaps ($210–$1,500) costs less than trapping every fall.
- Skip the plan if it's a one-off.A single wasp nest ($130–$810) or ant trail ($100–$410) doesn't need a year contract. Plans pay off when the same bugs come back every season.
- Read the cancel terms.Some plans run a full year. Ask how to cancel and whether you must pay back the first-visit discount if you stop early.
- Bundle termite and general pest.Many companies price a combined plan below two separate ones. A termite renewal alone runs $210–$1,000 a year.
- Get two quotes for big jobs.For bed bugs ($1,550–$6,100 whole home) or termites ($820–$3,050 and up), ask two companies for the same scope and warranty. The spread is often hundreds.
Get these in writing from any St. Louis company before you pay or sign a plan:
- The company's state license number and proof of insurance
- Which pests are covered, and which cost extra (termites, bed bugs, rodents, wildlife)
- Inside, outside or both, and the home size the price is based on
- The products to be used, and any prep or time away from home
- How many visits, and the price of each one
- Free return visits between services: yes or no
- The warranty, and for termites, whether it covers retreatment only or repairs too
- Contract length, auto-renewal and how to cancel

$210–$610 to trap and remove the animal, more if it's in the attic or chimney. Closing the way in is extra and is what stops the next one.
Is pest control treatment safe for kids and pets?
Licensed companies use products approved for home use and tell you how long to stay off treated areas, often until sprays dry. Tell them about pets, fish tanks and anyone with asthma before the visit.
