Instead, opening the wall set off a flood of acorns that seemed to have no end, revealing a problem far bigger than a simple repair job.
Behind the Wall: An Unbelievable Stockpile
By the time the cleanup finished, Castro and his team had removed approximately 700 pounds of acorns, enough to fill roughly eight large trash bags. A woodpecker had been using the small openings in the siding to store food, slowly turning the entire wall cavity into a hidden pantry.
From the outside, the damage had given almost no indication of the volume concealed within. Castro, whose pest-control career spans more than two decades, called it one of the strangest assignments he’d ever handled.
Resolving the Mystery
Despite the staggering discovery, the woodpecker responsible was left unharmed. The openings in the siding were patched, and new siding was installed to make the home less appealing as a future storage site.
The episode offers a practical lesson for homeowners: recurring holes in exterior walls deserve real investigation rather than a quick patch job. Wildlife may be seeking food storage, nesting space, or shelter, and professional guidance can address the cause without harming the animal.
One detail remains unknown—exactly how long it took for the woodpecker to build such a remarkable stockpile, one small delivery at a time.
