Technician inspecting a roofline for roof rat entry points in Plano, TX

Almost every home in Plano sits on a slab foundation, not a crawl space, which changes which rat you're actually dealing with. Norway rats still show up along fence lines, in dense mulch beds, and burrowed next to an AC condenser pad or a stacked woodpile, but the rat we get called about most is the roof rat — a lean climber that uses mature trees, power lines, and fence tops to reach a roofline and slip into an attic through a gap in the fascia, a torn soffit panel, or a roof-to-wall seam that's opened up over the years. In neighborhoods with heavy tree canopy near Willow Bend and along the creek corridors north of Legacy West, roof rats are the dominant problem, not the exception, and homeowners there are often surprised to learn the activity they're hearing overhead has nothing to do with their foundation at all.

North Texas's clay soil adds a second wrinkle homeowners rarely think about. That soil expands when it's wet and shrinks hard during a summer drought, and the movement opens and closes small gaps at slab edges, around weep holes, and where utility lines penetrate the foundation — exactly the size gap a young rat can use, even where the same spot looked tight the year before. Combine that with 100-degree stretches that push rats indoors chasing water and the cool air coming off attic ductwork, and you get pressure that doesn't really let up with the seasons the way it does farther north. Plano's winters are mild enough that we don't see the hard die-off some other regions do; activity runs closer to year-round, with a real but softer uptick as it cools off in October and November.

We start every job with an inspection, not a bait drop — walking the roofline with binoculars and a ladder, checking the attic with a flashlight along every joist run, and circling the slab perimeter for droppings, gnaw marks, grease rubs, and burrow sign to confirm whether we're dealing with roof rats working the attic, Norway rats working the ground level, or both. That determines where traps go and where exclusion work needs to focus, and it's the difference between a plan that works and one that just guesses. We trap the active population first; sealing a home with rats still inside just traps them in your attic or wall void instead of outside it, which almost always makes the smell and the noise worse before it gets better.

Once activity is under control, every entry point we found gets sealed with heavy-gauge hardware cloth, galvanized flashing, or mortar patching sized to the gap — materials a rat's teeth won't get through in a season, unlike foam or loose steel wool packed in and left alone. You get a written report of what we found and sealed, backed by a workmanship warranty on the exclusion work.

Roof Rats vs. Norway Rats in Plano

Roof rats are the climbers — slim, long-tailed, with large ears and a pointed nose, built to travel a power line or an overhanging limb straight onto a roof. They're the more common rat we find in Plano's tree-heavy neighborhoods, working fascia gaps, torn soffit screens, and roof-to-wall seams to get into an attic, and once inside they'll travel down through wall voids to reach a kitchen or garage rather than staying put in one spot. Norway rats are heavier, blunt-nosed, and stay lower, denning in mulch beds, under sheds, next to AC pads, or along a fence line where landscaping gives them cover. Because most Plano homes have no crawl space for a Norway rat to move into, ground-level activity here tends to stay outdoors longer, working the yard and perimeter before it ever finds a slab-edge gap into the house — a different pattern than cities with open crawl spaces, where they'd already be underneath the structure and harder to spot from ground level.

Why the Attic Is Ground Zero on a Slab Home

With almost no crawl space to speak of in Plano, the attic does double duty as the main way a rat gets deep into a house. A roof rat doesn't need a foundation gap at all — it needs one weak spot along the roofline, and from there it has the whole attic, and often the wall voids running down from it into the kitchen, garage, and bedroom closets. That's why our inspection always starts at the roofline and attic access, checking for gnaw marks around vent boots, gaps where a satellite dish or solar mount penetrates the roof deck, and daylight showing through a soffit return before we ever look at ground level. Homes with two-story sections or a steep roof pitch often have a blind spot along the upper roofline that a homeowner has never actually seen up close, and that's frequently where the real access point turns out to be, which is exactly why we go up on a ladder rather than inspecting from the driveway.

Signs of a Rat Infestation

Rats are cautious and mostly active after dark, so most homeowners hear activity before they see it — scratching, rolling, or scampering overhead near the roofline once the house is quiet, sometimes moving in a fairly straight line as the rat travels a joist from one end of the attic to the other. Look for dark, capsule-shaped droppings near the garage, pantry, or attic hatch, greasy rub marks along attic joists and fence tops where the same path gets used night after night, and gnaw marks on wood trim, PVC, or wiring insulation. Outside, watch fence lines and mulch beds for smooth two-to-four-inch burrow openings, and check AC condenser pads and utility penetrations for fresh digging or a chewed gap at the slab edge. A pet suddenly fixated on one spot along a wall or the attic hatch is also a reliable early tell most homeowners overlook, along with an unexplained pet-food smell near a garage corner that turns out to be a stash site.

Our Rat Removal Process

We inspect the full roofline, attic, and slab perimeter first to confirm species and map where activity is concentrated before setting a single trap. Snap traps and, where needed, enclosed tamper-resistant bait stations go on attic joists, along fence lines, or next to a confirmed burrow — never scattered around a garage floor on the assumption that more traps means faster results. We check and reset on a schedule until sign of activity stops, adjusting placement each visit based on where fresh droppings or gnaw marks are actually showing up, then move into exclusion, because sealing a house with an active population still inside just relocates the problem into your walls where it's harder and more expensive to reach. Each visit is logged so you can see catch counts and activity trending down rather than relying on our word alone.

Sealing Rats Out for Good

A rat can flatten its body through a gap about the width of a quarter, so exclusion has to be thorough, not a quick patch on the one hole you noticed. We seal roofline and soffit gaps, gable vents, utility penetrations, and slab-edge weep holes with heavy hardware cloth, galvanized flashing, and mortar — materials that hold up against constant gnawing, unlike foam alone, which a determined rat works through in days, sometimes hours if it's motivated to get back to a nest. Every point we seal is documented with a photo and covered under our workmanship warranty, so there's a record if a question ever comes up later, whether that's from you, a future buyer, or an insurance adjuster asking what work was actually performed and when.

Rats Around AC Units, Sheds & Landscaping

Ground-level rat sign in Plano tends to cluster around a handful of predictable spots: the shaded gap under a raised AC condenser pad, a storage shed with a gap under the wall track, dense ornamental grasses or ivy against a fence line, and a woodpile or stacked landscaping material left against the house. These spots offer the same thing a burrow would in the wild — cover, shade, and proximity to a water source like an AC drain line or a leaking hose bib. We check every one of these areas on a residential inspection, since a homeowner who's only looked at the roofline can easily miss a Norway rat burrow that's been active for weeks a few feet from the back patio.
