Roof Rats Reach Felton Roofs Through the Branches, Not Across the Yard

Roof rats are arboreal, and Felton hands them a highway. Henry Cowell Redwoods State Park wraps the town, and second-growth redwood and Douglas fir close over most streets. A rat that never touches the ground can move from park canopy to a bay laurel in your yard to a limb over the roof to the gap where the eave meets the fascia.

That is why ground-level bait on its own disappoints people here. The source population lives in the forest and it is not leaving, so the pressure is permanent. What you control is whether the structure is open. Down in Felton Grove, where the houses sit low on the river terrace and second growth crowds the lots, we find entry at roof-to-wall junctions, unscreened attic vents, and the gap behind chimney flashing far more often than at the foundation.

Cabin-era construction adds to it. Board-and-batten walls, add-on rooms with mismatched rooflines, and crawl-space vent screens rusted through after decades of San Lorenzo Valley rain each give a rat a quarter-inch start, which is all the opening it needs. Once they are in the attic, the insulation shows it first — flattened runways through the fill and nest chambers hollowed out near the eaves. That is usually what a homeowner finds when they finally go up to look for the noise.
