Noises overhead, droppings on rafters, and gnaw marks in the attic point to roof rats. These agile climbers enter along branches, utility lines, and roofline gaps, then nest in attics and soffits — a fire risk from gnawed wiring and a contamination problem in your insulation.
What’s most likely going on
Roof rats prefer upper levels and reach the attic by climbing overhanging branches, wires, and gaps at the roofline and soffits. Pointed droppings and overhead nighttime noise are the giveaways.
What it means for your home
Gnawed wiring in the attic is a genuine fire hazard, and droppings and urine contaminate insulation and stored items. Roof rats reproduce rapidly and are hard to exclude without sealing elevated entry points.
What to do next
We identify the elevated entry points, remove the rats, seal roofline and soffit gaps, trim access routes, and restore fouled insulation where needed. You can read more in our Pest Library entry on roof rats, or head straight to our Rodent Control service.

Frequently asked questions
How are rats getting all the way up in my attic?
They climb — overhanging branches, utility lines, and roofline gaps. Cutting that access and sealing the gaps is essential.
Is the noise at night rats or something else?
Persistent overhead noise usually means roof rats. An inspection confirms the species and the entry points.
