Rodent Control in Texas
Mice and rats often move indoors in Texas seeking shelter from extreme summer heat or after storm events disrupt their outdoor habitat.
Signs of a rodent problem
- Droppings near food storage, in cabinets, or along baseboards
- Gnaw marks on wiring, wood, or packaging
- Scratching sounds in walls or attics, especially at night
- A distinct musky odor in enclosed spaces
Field mice moving in from surrounding farmland are a recurring problem on the South Plains — see pest control in Lubbock for how that plays out locally.
Why entry point sealing matters
Traps alone rarely solve an ongoing rodent problem — if there’s an entry point, more will keep coming in. Professional rodent control typically combines removal with identifying and sealing how they’re getting in.
Which rodents get into Texas homes
Two species account for most residential calls, and they behave differently enough to change the response:
- House mice — small enough to pass through a gap the width of a pencil. They nest close to a food source, so activity tends to concentrate in kitchens, pantries and garages.
- Roof rats — climbers, common in the eastern and coastal parts of the state. They enter high: roof lines, soffit gaps, tree limbs touching the structure, and vent openings.
- Norway rats — ground-level burrowers, associated with crawl spaces, foundation gaps and utility trenches.
Knowing which one you have changes where the exclusion work happens. Droppings, gnaw marks and the height at which you hear movement are the usual indicators, and a technician will identify the species before proposing a plan.
Signs worth acting on
- Scratching or scurrying overhead at night, or inside a wall cavity
- Droppings along walls, behind appliances or in cupboards
- Gnaw marks on packaging, cabling or timber
- A persistent musky odour in an enclosed space
- Shredded insulation, paper or fabric used as nesting material
- Grease marks along a skirting board — rodents follow the same route repeatedly
Why exclusion comes before trapping
Removing the rodents currently inside without closing the way in produces a temporary result: the population replaces itself from outside. A structured approach seals the entry points first, then addresses the animals already present.
The entry points that matter most in Texas homes are the garage door seal, gaps where gas, water and cable lines pass through the wall, soffit and roof-line junctions, weep holes without guards, and crawl space vents with damaged screening.
What a professional visit typically covers
- Identifying the species and mapping the routes in use
- Sealing entry points with material rodents cannot chew through
- Placing traps or bait stations according to the routes identified, not at random
- Checking for contaminated insulation or nesting material that needs removal
- A follow-up visit to confirm the activity has stopped
Preventive steps that hold
- Fit or replace the garage door bottom seal — the most common entry route in Texas homes
- Trim tree limbs back from the roof line, which removes the access route for roof rats
- Store pet food, birdseed and grain in sealed containers rather than bags
- Screen crawl space vents and check them after storms
- Keep firewood off the ground and away from the structure
Common questions
Will traps alone solve it?
They address the animals present but not the access. Without exclusion the problem tends to return, which is why most providers treat sealing as the substantive part of the job.
How small a gap can a mouse use?
Smaller than most homeowners expect — roughly the diameter of a pencil is enough for a house mouse. That is why inspections concentrate on utility penetrations and door seals rather than obvious holes.
Is rodent damage covered by insurance?
Generally not. Damage caused by rodents and insects is a common exclusion in homeowners policies — our page on whether pest control is covered by insurance sets out what the Texas Department of Insurance says.
How should I prepare for the visit?
Note where you hear activity and at what time, clear access to the garage perimeter, under-sink cabinets and any crawl space hatch, and mention any recent storm damage to soffits or screening.
