Daytime scampering overhead usually means squirrels, and their chewing near wiring is a fire risk you do not want to leave in the attic.
Hearing scampering in the attic during the day? That is usually squirrels, not rats, since squirrels are active in daylight. We get them out, check for babies in nesting season, and seal the vents and gaps they used. Their constant chewing on wiring is a real fire risk, so it is worth handling quickly.
Squirrels are rodents, so their teeth never stop growing and they gnaw constantly, including on wood framing and electrical wiring. A nest in the attic is not just noise; chewed insulation on wiring is a documented fire hazard, which is why a squirrel in the attic is worth handling promptly.
You hear squirrels during the day because, unlike rats, they are active in daylight. We remove them, check for young in nesting season, then seal gable vents, soffit gaps and roof returns with heavy-gauge mesh and trim back the branches giving them a bridge to the roof.
