Scratching in the ceiling at night on the Gulf Coast is almost always roof rats. They climb in along the roofline, so that is where the fix has to happen.
Nighttime scratching in a Missouri City ceiling is usually the roof rat, the climbing rat that dominates the Texas Gulf Coast and nests high in attics. Yellow Rose removes them, then seals the roof returns, soffit gaps, vent screens and any branches touching the house, so the roofline they travel is closed off for good.
Roof rats are agile climbers that travel fences, power lines, branches and the roofline, then slip in at the roof returns and soffit gaps to nest high. That is why you hear them in the ceiling at night. Sealing the ground floor does nothing; the fix is up at the roofline.
We read the actual travel routes in the attic, remove the colony, then close the roofline entry points with materials a rat cannot chew and trim back the branches giving them a bridge to the roof.
