Houston's mild winters, green bayou corridors, sprawling neighborhoods and plentiful food sources add up to year-round rodent activity. There is no cold season to slow them down, and homeowners from the Heights to Clear Lake to Sugar Land-area subdivisions report scratching in attics and droppings in garages in every month.
The rodents you will meet
Roof rats are the typical attic invaders. They climb well, travel along fences and power lines, and nest in dense vegetation and tall trees, particularly in neighborhoods with mature canopy. Norway rats burrow in the ground near foundations, drainage ditches and bayou banks. House mice live inside the home and can breed constantly in the warm climate. Cotton rats and other native rodents sometimes show up near undeveloped tracts.
Houston conditions that help them
- Bayou and ditch systems provide water, cover and travel routes.
- Heavy rain and flooding push rodents out of burrows and into buildings.
- Fruit trees, pecan trees and bird feeders provide steady food.
- Attic vents, soffits and gaps around roof penetrations in tract homes offer easy access.
- Garages and sheds filled with stored goods become nesting sites.
Spotting the signs
Roof rats are noisiest around dusk and again before dawn, creating thumps and scratches overhead. Look for droppings along attic beams and near HVAC equipment, rub marks along pipes, chewed wires or insulation, gnawed pecans and fruit under trees, and trails through insulation. Dogs may bark at the wall or the ceiling. Burrows with smooth edges appear along fences, foundations and under slabs when Norway rats are active.
How a licensed provider handles the job
An experienced technician starts by tracing travel routes: branches that touch the roof, utility lines, fence tops, and gaps where plumbing or AC lines pass through walls. In the attic they look for nests and contamination. Exclusion with metal flashing, hardware cloth and sealant is the foundation of any lasting solution. Traps and tamper-resistant bait stations help remove the existing population. Where droppings and urine have soaked insulation, providers may recommend cleanup and replacement.
After heavy storms or floods, a repeat inspection is useful; displaced rodents often settle in homes that seemed secure before.
What homeowners can do
- Cut back tree limbs touching the roof and keep shrubs trimmed off walls.
- Harvest fruit and pecans promptly and rake what falls.
- Seal pet food and bird seed in metal bins.
- Close gaps at the garage door seal and around pipe penetrations.
- Store firewood and debris away from the house.

Rodent questions in Houston
Why do I hear noises in the attic at night?
Roof rats are nocturnal and active after dusk. Nighttime scratching or running overhead is a typical sign.
Can rodents come in after a storm?
Yes, flooding and heavy rain can push them out of burrows and toward dry buildings.
Is DIY trapping enough?
It may catch a few, but without sealing entry points new rodents will keep coming.
Should I replace attic insulation?
If it is contaminated with droppings or urine, cleanup or replacement is often recommended. A provider can assess it.
