From the first call to the final walk-through, Nex Pest Control clears out roaches, rodents, termites, and stinging insects across Alton so you can stop checking the baseboards and get back to your day.
Skip the guesswork. We'll identify exactly what you're dealing with and hand you a straightforward, written treatment plan before we start.

We built Nex Pest Control around a simple idea: send a technician who actually knows Alton'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 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.
We started Nex Pest Control after seeing how many Alton families were re-paying for the same unresolved infestation every few months. 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.
Any one of these on its own isn't necessarily an emergency, but two or more together usually mean the infestation has moved past the point where a store-bought spray will handle it. 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.
Beyond trapping, we handle exclusion work: hardware-cloth screening on vents, door sweeps, and sealing utility lines so Alton properties stay rodent-free after the initial removal. Larger nuisance wildlife gets the same exclusion-first approach as rodents, since removal alone rarely solves the underlying access problem.
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.
A quick call to +1-844-564-2570 gets a technician on the calendar, usually within 24 hours.
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.
You're never letting an unlicensed contractor into your Alton property — every visit is backed by insurance and proper credentials. Ask to see credentials at the door — every Alton technician carries them as a matter of routine.
Most Alton calls placed before early afternoon get a technician out that same day. Evening and weekend appointments are also available for situations that can't wait until Monday.
We choose the lowest-impact effective product for each Alton 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.
Every Alton estimate is written down and agreed to up front, so the invoice never surprises you. Nothing gets added to the invoice without your sign-off first.
Our Alton guarantee means a callback for recurring activity is free, not an upsell. The guarantee period and terms are spelled out in your service agreement, not buried in fine print.
We track pest activity by Alton neighborhood, so your technician already knows what's typical for your area before they arrive. That local pattern data means fewer guesses and a treatment plan built around what's actually common on your street.
Our guarantee is simple: pay for a result, not just a visit. If activity continues in your Alton property after treatment, follow-up service is included, not billed separately.
The terms are spoken plainly at the time of service so there's never a surprise when you call back about recurring activity.
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.
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.
A yellow jacket nest near the kids' play area got handled within hours of calling. Fast and no drama.
As a small business owner, I needed paperwork ready for surprise inspections. Their commercial plan handles that automatically now.
We finally got our backyard back after Nex Pest Control treated the shrub line and cleared out a couple of spots we didn't even know were holding water.
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.
