Homeowners and property managers across Alton call Nex Pest Control when store-bought sprays stop working, because we treat the source of the infestation, not just the bugs you can see.
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.

Technicians at Nex Pest Control have crawled more Alton attics and inspected more Alton slabs than we can count, and that hands-on time is exactly why our treatment plans hold up. 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 Alton 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 Alton 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 Alton 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 Alton homeowners report most often right before they call us.
Seeing several of these signs at once in your Alton 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.
Whatever's moved into your Alton property, our technicians have a specific protocol for it — not a one-size-fits-all spray.
A general service visit targets entry points around your Alton home's foundation, utility lines, and vents, then follows up quarterly so pressure never has a chance to build back up. We also treat interior hot spots like under-sink cabinets and utility closets, not just the outside perimeter.
Termite damage in Alton 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. Bait stations are monitored on a set schedule after installation, so activity is caught early instead of at the next annual visit.
Rodent calls in Alton almost always trace back to a gap smaller than a quarter, so our technicians don't just set traps, they find and close the entry point too. 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 Alton 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.
Barrier sprays go on foliage, fence lines, and other resting spots around your Alton yard, so you can get evenings back on the patio without getting eaten alive. 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.
From loading-dock rodent stations to kitchen-area cockroach monitoring, our commercial Alton clients get a discreet, documented program instead of a single reactive spray. Technicians can service before or after operating hours so treatment never disrupts customers or staff.
Call +1-844-564-2570 and describe what you're seeing — we'll often schedule same-day.
A technician walks your Alton property, identifies the pest, and points out entry points.
You get a flat-rate quote before treatment starts — no surprise line items afterward.
If activity continues after treatment, we come back at no extra charge under our guarantee.
Every technician we send into a Alton home carries state licensing and our company's liability coverage. Ask to see credentials at the door — every Alton technician carries them as a matter of routine.
We keep same-day slots open specifically for Alton 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 Alton job, and walk you through re-entry timing before we leave. We're happy to answer product questions in detail if anyone in the home has sensitivities.
Every Alton estimate is written down and agreed to up front, so the invoice never surprises you. 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.
If pests come back between scheduled Alton visits, we come back too, at no additional cost. Ask your technician for the specific guarantee window that applies to your treatment.
We track pest activity by Alton neighborhood, so your technician already knows what's typical for your area before they arrive. It's the difference between a generic spray and a plan built around what's actually happening nearby.
We stand behind every Alton treatment plan in writing. If the pest we treated for is still active after the recommended window, we return and re-treat at no charge — that's not a marketing line, it's in your service agreement.
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."
Had a roach problem that three store-bought traps couldn't touch. One visit from Nex Pest Control and they haven't been back in two months.
The termite inspection was thorough — they showed me photos of the damage under the porch before recommending anything.
Rodent noise in the attic kept us up for a week. Nex Pest Control's guy traced it to a roofline gap and closed it before setting a single trap.
They inspected every seam of the mattress and baseboard, explained exactly what they found, and the follow-up check came back clean.
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.
