Rodent Control for Texas Homes
Updated June 14, 2026
When rodents get into a Texas home, it's most often one of two: the house mouse, small and quick to set up in garages, pantries, and wall voids, or the roof rat, an agile climber that travels power lines and tree limbs into attics and upper walls. (The larger, ground-burrowing Norway rat shows up too, more around sewers and outbuildings.) Rodents aren't just unsettling — they breed fast, contaminate food and surfaces, spread disease, and gnaw constantly, including on electrical wiring, which is a genuine house-fire risk. And because a mouse fits through a dime-sized gap and a rat through a quarter-sized one, trapping alone never finishes the job — sealing them out does.
Which rodent you likely have
House mice are small (a couple inches of body), curious, and stay close to their nest in garages, pantries, appliances, and wall voids; they breed year-round and a few become many quickly. Roof rats are sleek climbers that prefer the upper parts of a structure — attics, soffits, upper walls — and travel along fences, wires, and tree limbs; they're very common in Texas. Norway rats are bigger and burrow at ground level around foundations, woodpiles, and sewers.
How they get in
The numbers surprise people: a mouse needs only a dime-sized hole, a rat a quarter-sized one. Common entries are gaps where utility lines and pipes penetrate walls, weep holes, garage-door corners, gaps under doors, roofline and soffit gaps (roof rats' favorite), attic and gable vents, and the chase around the chimney. Overhanging tree limbs are a highway straight to the roof.
The signs
Droppings along walls and in cabinets or the attic; gnaw marks on food packaging, wood, and wiring; greasy rub marks along travel routes; scratching or scurrying sounds in walls and ceilings (especially at night for roof rats); a musky odor; and shredded nesting material. Roof rats announce themselves overhead; mice down low.
Why they're a real risk, not just a nuisance
Rodents contaminate food and surfaces with droppings and urine and can spread disease; their constant gnawing damages structures and, critically, chews through electrical insulation — a documented cause of house fires. A small problem also doesn't stay small: rodents reproduce fast, so early action matters.
DIY vs. a pro — honestly
Snap traps can knock down a light mouse problem if you place enough of them correctly and stay on it. Where DIY falls short: finding and sealing every entry point (especially roof-rat access high on the structure), handling an established or recurring infestation, and doing it safely (rodent droppings and nesting are a health hazard to clean up). Without exclusion, you're just thinning a population that keeps refilling from outside.
How Root handles rodents
We combine trapping to remove the active population with exclusion — finding and sealing the entry points so they can't keep coming back — plus sanitation guidance to remove what's attracting them. We pay particular attention to the roofline and attic access that roof rats exploit here, and to the ground-level gaps mice use. Because our techs work these neighborhoods, they know the local construction and tree-cover patterns that drive rodent pressure. Same-day service is available when capacity allows.
