Homeowners and property managers across Harlingen 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.

We built Nex Pest Control around a simple idea: send a technician who actually knows Harlingen'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.
Our Harlingen crew carries state pest-control licensing, general liability coverage, and ongoing training on label updates for every product we use, so nothing applied in your home is a guess. That expertise is what lets us diagnose the real problem instead of just masking the symptoms with a spray.
Nex Pest Control exists because Harlingen 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 Harlingen 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 Harlingen homeowners report most often right before they call us.
Seeing several of these signs at once in your Harlingen 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 Harlingen properties actually deal with, from routine ant trails to serious structural termite damage.
We handle the pests that show up in nearly every Harlingen 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.
We inspect the soil line, crawl space, and wood framing of Harlingen homes for active termite activity, then install a liquid or bait-station barrier depending on what the inspection shows. 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 Harlingen properties stay rodent-free after the initial removal. We also handle occasional wildlife calls — squirrels in the attic, raccoons under a deck — with humane trapping and exclusion.
Our Harlingen 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.
Barrier sprays go on foliage, fence lines, and other resting spots around your Harlingen 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 Harlingen business's hours, documentation needs, and industry requirements, with service logs ready for any audit. 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.
We inspect inside and out, confirm the species, and explain exactly what we found.
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 Harlingen property — every visit is backed by insurance and proper credentials. Ask to see credentials at the door — every Harlingen technician carries them as a matter of routine.
We keep same-day slots open specifically for Harlingen emergencies like active wasp nests or a sudden rodent sighting. Evening and weekend appointments are also available for situations that can't wait until Monday.
Our Harlingen 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 Harlingen 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 Harlingen 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 Harlingen 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.
We stand behind every Harlingen 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.

The termite inspection was thorough — they showed me photos of the damage under the porch before recommending anything.
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.
