Open fields, creek corridors and quickly developing subdivisions make Arlington a place where wildlife and housing sit side by side. When a neighborhood is built on former prairie or farmland, the rodents that lived there do not vanish; they relocate into walls, garages and attics. North Texas adds a twist: sudden cold snaps after warm spells push animals indoors fast.
Who is in your attic
House mice are the most frequent invaders and can squeeze through a gap the width of a pencil. Norway rats burrow along foundations, drainage ditches and creek banks, such as those following Johnson Creek, and enter through ground-level gaps. Roof rats are present in Texas as well and favor attics and tree canopies. Each leaves different clues: mouse droppings resemble grains of rice, while Norway rat droppings are larger and blunt-ended.
Why they are drawn to Arlington properties
- Brick-veneer houses with weep holes and loose garage door seals at the base.
- Older ranch homes where attic vents and soffits have deteriorated.
- Apartment complexes with shared dumpsters, which feed rats and mice close to buildings.
- Fruit and pecan trees that drop food into yards.
- Bird feeders and pet food left outdoors overnight.
Signs to take seriously
Scratching in walls at night, gnaw marks on boxes or wiring, grease smears along baseboards, and droppings in the pantry all indicate activity. In the garage, look for shredded insulation or nests in stored fabric. A car that suddenly acts up can even be a clue, since rodents sometimes chew wiring under the hood. If you smell a stale odor in the attic or hear thumping, call early; breeding is fast and wiring damage is a fire concern.
How the work is done
A technician starts with a full inspection, looking for rub marks, runways and entry holes. Removal generally uses snap traps, enclosed bait stations outdoors, and monitoring over several visits. Then comes exclusion, which is the part that keeps them out: steel wool and caulk for small gaps, metal flashing and mesh for larger ones, and new door sweeps on garages. Cleanup and insulation replacement may follow if contamination is heavy.
What homeowners can do
- Move firewood, lumber and storage boxes away from exterior walls.
- Switch cardboard storage in the garage to lidded plastic tubs.
- Close gaps larger than a quarter inch around pipes and wires.
- Keep trash in lidded bins and clear fallen pecans and fruit promptly.
- Fill burrows near foundations only after a professional confirms they are inactive.

Why do I hear noises mostly at night?
Rats and mice are nocturnal. Quiet evening hours in the attic or walls are when they forage and move.
Are poison baits safe indoors?
They can create problems if animals die in walls or if pets and children find them. Many professionals prefer traps inside homes and bait stations only outdoors.
Can rodents get into a newer home in Arlington?
Yes. Even recently built homes can have construction gaps around plumbing and vents that rodents find quickly.
How can I tell if the problem is solved?
No new droppings, no noises and no fresh gnaw marks over a few weeks suggest success, and a provider will usually check back.
