They can use palm trees and other elevated vegetation, and nearby branches can make roof access easier for climbing rats.
Roof rats are strong climbers. In Los Angeles, trees, fences, utility lines, and other elevated routes can bring them close to roofs. Once they gain access to your attic, rats can then stay a while, which is part of what makes them so frustrating, especially when you hear them scratching around up there at night.
Dense palm foliage can certainly give roof rats an easy way into the attic. But that doesn't mean every rat in a palm tree is going to target your attic, nor does it mean palm trees are the only way in. Roof rats are capable of climbing stucco, brick, vines, and all manner of textured surfaces to get where they want to go.
One thing that’s for sure is that to have a roof rat problem indoors, rats must have an entry point. Gaps around rooflines, vents, eaves, damaged screening, and utility penetrations can provide access once a rat reaches the building. It’s a good idea to first start by caulking gaps and replacing worn screens or vents to reduce entry points.
After doing that, it can then help to trim trees or branches so they’re not touching the side of the house or hanging over the roof. There is no reason to make it easier for rats to get inside, after all.
Keep an eye out for signs of rodent infestations. That includes droppings and gnaw marks, a musty odor, piles of shredded material like cardboard or insulation, and the sound of scratching in walls or the attic at night. Any can indicate a problem, and would justify a call to a professional.
