Excessive pine cone debris—tan and green cones, plus gnawed fragments—is the work of squirrels harvesting seeds. They perch high in the tree, extract seeds, and drop the remains. Like eating muscadine grapes and spitting out skins, squirrels discard the inedible parts.
The “rain” of debris lasts only a few weeks during peak seed maturity. No control needed; it’s a natural seasonal event.
