Rat Removal in Marietta GA: Roof Rats and Norway Rats

Roof rats are the climbers. They are slender, dark, and comfortable above ground, which is why Marietta homeowners usually find them in attics, rooflines, and upper walls. They travel along tree limbs, power lines, and fences, then slip in through gaps at the eaves, roof vents, and where the roof meets the wall. If you hear scratching overhead at night, especially in the fall, roof rats are the likely culprit.

Norway rats are the burrowers. They are heavier, brownish-gray, and prefer ground level — crawl spaces, basements, garages, and the base of foundations. They dig burrows along foundations and under sheds, and they enter through gaps at ground level, damaged vents, and gaps around pipes and doors. Norway rats are common around older Marietta neighborhoods with mature landscaping, woodpiles, and outbuildings.

Telling the two apart matters because the trapping and exclusion plan is different. Roof rat work concentrates on the roofline, attic, and upper structure. Norway rat work concentrates on the foundation, crawl space, and yard. A good inspection identifies the species first — from droppings, rub marks, runways, and where the activity is heard — and the plan follows from there.

Both species breed fast. A small problem in September can become a large one by November if it is left alone, which is why rat removal in Marietta is usually an urgent job, not a wait-and-see one. Rats also gnaw constantly to keep their teeth worn down, which puts wiring, pipes, and wood framing at risk.

The most reliable signs are sounds and droppings. Scratching, scurrying, or gnawing noises in the attic or walls at night — when rats are most active — are a strong indicator. Droppings are another: roof rat droppings are pointed and curved, about half an inch long, while Norway rat droppings are blunter and larger. Fresh droppings are dark and soft; older ones dry out and turn gray.

Other signs include greasy rub marks along walls, baseboards, and rafters where rats travel the same routes, gnaw marks on wood, wiring, or food packaging, and a musky, stale odor in enclosed spaces. In attics, look for disturbed or compressed insulation, nesting material made from shredded paper or fabric, and burrows or holes along the foundation outside.

• Scratching, scurrying, or gnawing sounds in the attic or walls at night
• Droppings in the attic, garage, pantry, or along baseboards
• Greasy rub marks on rafters, pipes, or wall edges
• Gnaw marks on wood, wiring, food packaging, or plastic bins
• A stale, musky odor in the attic, crawl space, or a closed room
• Burrows or holes along the foundation, under sheds, or near woodpiles
• A rat sighting in the yard, on a fence, or on a power line near the roof

Rats can squeeze through a gap the size of a quarter, and a home has dozens of such gaps: where the roof meets the wall, around vents and chimneys, where pipes and wires enter, and along damaged fascia. Sealing those gaps with materials rats cannot gnaw through is the difference between a one-time job and a recurring problem.

That is why our rat removal programs pair trapping with exclusion. The order matters too: seal too early and you can trap rats inside; trap first, confirm activity has dropped, then seal. A plan that skips either step usually ends with a callback.

After exclusion, prevention is mostly maintenance: keep tree limbs trimmed back from the roof, store firewood away from the house, keep pet food indoors, and check vents and rooflines once or twice a year. Our preventative maintenance programs handle that check for homeowners who would rather not climb into the attic themselves.

Homes near Marietta Square and the historic district have the oldest rooflines and the most gaps for roof rats to exploit, and the mature trees in those neighborhoods give roof rats a highway straight to the attic. East Cobb subdivisions with heavy tree cover see the same pattern, with roof rats traveling from tree to roof without ever touching the ground.

Norway rats show up more around ground-level features: crawl spaces in mid-century ranch homes, garages and sheds in West Cobb, and properties near streams and drainage areas. Wherever rats are active, the same rules apply: inspect first, trap the population, seal the entries, and clean up.
