From the first call to the final walk-through, Nex Pest Control clears out roaches, rodents, termites, and stinging insects across St. Louis so you can stop checking the baseboards and get back to your day.
Not sure what's living in your walls? A technician will confirm the pest, show you the entry points, and quote a flat price on the spot.

We built Nex Pest Control around a simple idea: send a technician who actually knows St. Louis's housing stock, soil type, and pest pressure, instead of reading from a national script. We're not a call center dispatching a stranger — the person who inspects your property is the same person who treats it and comes back if anything returns.
We hire slowly and train constantly, which is why our St. Louis technicians can tell you the difference between carpenter ant frass and termite droppings before they've even opened their toolbox. That expertise is what lets us diagnose the real problem instead of just masking the symptoms with a spray.
Nex Pest Control exists because St. Louis residents got tired of big-box pest brands that show up late, spray on autopilot, and vanish until the next quarterly visit. That's the standard we hold every job to, whether it's a single-family home, a rental property, or a small business storefront.
Every St. Louis job we complete gets logged against the season, the property type, and the pest, which is how our technicians walk in already knowing what's likely and what isn't. That local data shortens the inspection and sharpens the treatment plan from the very first visit.

Pests are good at staying hidden. These are the warning signs St. Louis homeowners report most often right before they call us.
Seeing several of these signs at once in your St. Louis property is a good indicator that the colony or nest is already established somewhere you can't easily reach. A same-day inspection will tell you exactly what you're dealing with instead of leaving you to guess.
Nex Pest Control covers the full range of pest issues St. Louis properties actually deal with, from routine ant trails to serious structural termite damage.
We handle the pests that show up in nearly every St. Louis home — ants trailing across the counter, roaches in the kitchen, spiders in the garage — with a barrier treatment reapplied on a schedule that fits your property. Interior baseboards, cabinets, and the garage get the same attention as the exterior perimeter, since that's usually where activity is first noticed.
Termite damage in St. Louis properties is often underway for years before it's visible, which is why our inspection checks the sill plate, foundation cracks, and any wood-to-soil contact points first. Liquid barrier treatments are mapped along the full foundation line, not just the section where swarmers were spotted.
We trap and remove mice and rats from St. Louis attics and crawl spaces, then seal the gaps they used to get in — usually around utility penetrations, garage door corners, and roofline gaps. We also handle occasional wildlife calls — squirrels in the attic, raccoons under a deck — with humane trapping and exclusion.
Bed bugs don't respond to a single spray, so St. Louis clients get a multi-visit plan: initial treatment, a follow-up inspection at two weeks, and a final clearance check. We'll also walk you through simple prep steps before the visit so the treatment is as effective as possible on the first pass.
We treat standing water sources, dense shrub lines, and shaded yard areas around St. Louis properties on a monthly cycle through peak season to knock down mosquito and tick populations. We can also flag standing-water sources on your property, like clogged gutters or unused planters, that keep re-seeding the mosquito population between visits.
St. Louis restaurants, retail stores, warehouses, and offices rely on us for scheduled service plans that keep them ready for a health inspection any day of the year. Technicians can service before or after operating hours so treatment never disrupts customers or staff.
Call +1-866-315-0243 and describe what you're seeing — we'll often schedule same-day.
A technician walks your St. Louis property, identifies the pest, and points out entry points.
We apply the agreed treatment the same visit, using the least invasive method that works.
Follow-up visits are scheduled automatically if the treatment calls for one.
Every technician we send into a St. Louis home carries state licensing and our company's liability coverage. Ask to see credentials at the door — every St. Louis technician carries them as a matter of routine.
We keep same-day slots open specifically for St. Louis emergencies like active wasp nests or a sudden rodent sighting. A dispatcher can usually tell you an arrival window within minutes of your call.
We choose the lowest-impact effective product for each St. Louis job, and walk you through re-entry timing before we leave. If you keep fish, reptiles, or birds, mention it before the visit so we can plan around them specifically.
You approve a flat quote before any St. Louis technician touches a single product — no hourly surprises. If the scope changes once we're inside — say, a second nest is found — we'll quote that separately before proceeding, not add it silently.
Our St. Louis guarantee means a callback for recurring activity is free, not an upsell. Ask your technician for the specific guarantee window that applies to your treatment.
Our technicians work St. Louis daily and know which neighborhoods see termite swarms first each spring. It's the difference between a generic spray and a plan built around what's actually happening nearby.
Our guarantee is simple: pay for a result, not just a visit. If activity continues in your St. Louis property after treatment, follow-up service is included, not billed separately.
This isn't a lifetime promise on every pest forever, but within the stated window it's unconditional — no forms to fill out, no argument about whether it "counts."
We'd tried everything on the shelf for roaches before calling Nex Pest Control. The technician found where they were nesting behind the dishwasher and that was that.
Found termite damage during a home inspection and Nex Pest Control had someone out the next morning with a real treatment plan, not just a scare tactic.
Mice got into our garage and the technician found the gap under the door we'd never have noticed ourselves. Sealed it and set traps same visit.
Bed bugs after a trip and I panicked, but the technician walked me through the whole process calmly and it was handled in two visits.
Wasps had built a nest right by our back door and the tech removed it same day without us even having to leave the house.
As a small business owner, I needed paperwork ready for surprise inspections. Their commercial plan handles that automatically now.
Mosquitoes made our patio unusable every evening until Nex Pest Control's monthly yard treatment brought that under control within a couple weeks.
Ant trails kept coming back every summer no matter what we sprayed ourselves, until a Nex Pest Control technician found and sealed the actual entry point along the foundation.
No matter which part of St. Louis you're in, Nex Pest Control can get a licensed technician to your door, usually the same day you call. We route technicians daily across St. Louis, so distance within our coverage zone rarely adds to your wait time.
We keep daily slots open for St. Louis emergencies, so most callers are seen within 24 hours.
Yes — we select products with re-entry times we'll walk you through, and we'll always tell you when it's safe to bring pets and kids back into treated rooms.
If the treated pest is still active after the guarantee period, the next visit is on us.
We quote a flat price on-site after inspecting, so there's no hourly rate or surprise add-ons on the invoice.
Only a small number of treatments require you to leave, and we'll tell you in advance if yours does.
