Property owners across St. Louis County 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 St. Louis County attics and inspected more St. Louis County 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 St. Louis County 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 was built on flat-rate pricing, real inspections, and a guarantee that means something — because that's what St. Louis County property owners 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.

Pests are good at staying hidden. These are the warning signs St. Louis County property owners 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 St. Louis County property, our technicians have a specific protocol for it — not a one-size-fits-all spray.
We handle the pests that show up in nearly every St. Louis County 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. We also treat interior hot spots like under-sink cabinets and utility closets, not just the outside perimeter.
Termite damage in St. Louis County 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.
Rodent calls across St. Louis County 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. Larger nuisance wildlife gets the same exclusion-first approach as rodents.
Our St. Louis County bed bug protocol starts with a room-by-room inspection using a flashlight and interceptor traps, followed by targeted heat or chemical treatment depending on the infestation size. Furniture, luggage, and closets get checked too, since bed bugs travel well beyond the bedroom once established.
We treat standing water sources, dense shrub lines, and shaded yard areas around St. Louis County properties on a monthly cycle through peak season to knock down mosquito and tick populations. One-time treatments are available ahead of an outdoor event if you need the yard clear for a specific date.
From loading-dock rodent stations to kitchen-area cockroach monitoring, our commercial St. Louis County 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.

Our 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 St. Louis County daily and know which towns see termite swarms first each spring. That local pattern data means fewer guesses and a treatment plan built around what's actually common nearby.
We stand behind every St. Louis County 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.
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 rather lose a little margin on a re-treat than lose your trust over a technicality, and that mindset shapes every St. Louis County service agreement we write.
