Scratching or scurrying in the ceiling at night in East Texas is most often roof rats — agile climbers that enter along trees, wires and roof lines through gaps as small as a quarter. Trapping removes them; sealing entry points (exclusion) keeps them out.
What animal is in my attic?
In East Texas, the usual culprit is the roof rat — a slender, agile climber that travels power lines and pine branches and slips into attics through gaps around eaves, soffits, vent stacks and roof returns. Its heavier cousin, the Norway rat, prefers ground level — crawl spaces, garages and foundation gaps — so where you hear the noise is a clue to which species you have. The sound profile: light scratching, scurrying or gnawing in the ceiling or walls, mostly at night (rats are nocturnal). Heavier daytime thumping suggests squirrels; slow dragging sounds can be raccoons or opossums — species matters because removal methods differ.
What are the warning signs?
- Droppings — spindle-shaped, along attic beams, in the garage or under the kitchen sink.
- Gnaw marks — on wood, stored boxes, and critically, on electrical wiring.
- Rub marks — greasy smudges along rafters and entry holes from oily fur.
- Nests — shredded insulation and paper packed into corners.
- Pets staring at the ceiling. They hear what you sleep through.
Why is this urgent rather than annoying?
Three reasons. Rats gnaw constantly to wear down their teeth, and gnawed wiring is a genuine fire hazard. They contaminate insulation and any space they occupy with droppings and urine. And they multiply fast — a pair in the fall becomes a population by spring. Cooler East Texas months push rodents indoors, so fall and winter are peak invasion season across the Piney Woods.
What are the failure modes?
- Poison in the attic. A poisoned rat dying in a wall void creates an odor problem you cannot reach — and secondary-poisoning risk for owls and pets.
- Traps without exclusion. Catch six rats and the entry holes invite the next family in. This is the single biggest reason DIY rodent control fails.
- Sealing rats in. Exclusion done before removal traps animals inside — order of operations matters.
How does professional rodent control end it?
Spot On's rodent control program runs the full sequence: a complete interior and exterior inspection to find every entry point, trapping and removal of the current population, exclusion work — sealing gaps, vents, garage seals and roof-line entries so the next rats can't get in — plus sanitation guidance and follow-up monitoring. That order (inspect → remove → seal → monitor) is what makes results stick, whether you're in Lufkin, Nacogdoches or Livingston.

Quick questions
How small a gap can a rat fit through?
Roof rats can squeeze through openings about the size of a quarter — and can gnaw smaller gaps larger. That's why professional exclusion targets every gap, not just the obvious holes.
Why do I only hear them at night?
Rats are nocturnal — activity typically starts shortly after the house quiets down. Regular daytime noise points to squirrels or a large, food-stressed rat population.
Does one rat mean an infestation?
Treat one rat as a warning shot: rats are social and breed quickly, and the entry point that admitted one will admit others. An inspection tells you whether you're early or late to the problem.
