Nex Pest Control sends licensed, background-checked technicians to homes and businesses across Alton the same day you call, with a written plan and a price you agree to before anyone touches a chemical.
Skip the guesswork. We'll identify exactly what you're dealing with and hand you a straightforward, written treatment plan before we start.

Nex Pest Control has spent years working Alton's neighborhoods block by block, learning which pests show up first when a season turns and which older homes tend to have gaps around the sill plate. 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.
Every technician on our Alton team is licensed, insured, and trained on the specific pests that thrive in this climate, from subterranean termites working the soil line to German cockroaches riding in on grocery boxes. That expertise is what lets us diagnose the real problem instead of just masking the symptoms with a spray.
Nex Pest Control was built on flat-rate pricing, real inspections, and a guarantee that means something — because that's what Alton homeowners actually asked for. 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.
Nex Pest Control covers the full range of pest issues Alton properties actually deal with, from routine ant trails to serious structural termite damage.
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. Liquid barrier treatments are mapped along the full foundation line, not just the section where swarmers were spotted.
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.
We treat mattresses, box springs, baseboards, and outlet covers — the actual hiding spots — rather than fogging a room and hoping for the best. 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.
We build commercial service schedules around your Alton business's hours, documentation needs, and industry requirements, with service logs ready for any audit. Every commercial visit ends with a signed service report you can file for your own compliance records.
Call +1-866-315-0243 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.
We apply the agreed treatment the same visit, using the least invasive method that works.
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. We can provide proof of both on request, before a technician ever steps inside.
Most Alton calls placed before early afternoon get a technician out that same day. A dispatcher can usually tell you an arrival window within minutes of your call.
Our Alton product selections follow EPA labeling closely, and we'll tell you exactly when it's safe to let kids and pets back into treated areas. We're happy to answer product questions in detail if anyone in the home has sensitivities.
You approve a flat quote before any Alton technician touches a single product — no hourly surprises. 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.
Our technicians work Alton daily and know which neighborhoods see termite swarms first each spring. That local pattern data means fewer guesses and a treatment plan built around what's actually common on your street.
Alton clients don't have to negotiate for a re-treat. If our records show the pest is still present after the guarantee period, the next visit is already covered.
The terms are spoken plainly at the time of service so there's never a surprise when you call back about recurring activity.
