They poured from the wall cavity in a steady stream.
Imagine cutting into a section of drywall expecting to find perhaps a handful of nuts, only to discover that the space behind it has effectively become a reservoir.
The more material Castro removed, the more acorns appeared.
At first, the sight was amusing and unusual.
Then the scale of the accumulation became apparent.
This wasn't a bird's small emergency food supply.
There were enormous quantities of acorns hidden inside the structure.
The wall itself had essentially become a giant container.
The Acorns Had Spread Through the Wall Cavities
Finding a concentrated pile in one small area would have been remarkable enough.
As additional sections were examined, Castro discovered that the acorns had accumulated through the cavities and reportedly reached toward the attic.
That detail transformed the story.
This wasn't something that had happened during a handful of visits.
The woodpecker had apparently returned again and again, repeatedly depositing food into the house.
Each individual trip probably seemed insignificant.
One bird carrying one acorn doesn't look capable of creating a major structural headache.
But repetition changes everything.
A single acorn becomes ten.
Ten become a hundred.
Hundreds become thousands.
And when the food continues dropping into spaces where it can't easily be seen—or retrieved—the accumulation can continue without anyone realizing what is happening.
For the homeowner, the evidence outside the house offered only a small clue.
Behind the siding was the real story.
Nearly 700 Pounds of Acorns Were Removed
Eventually, the amount removed from the property was estimated at roughly 700 pounds of acorns.
That number is what turned an already strange pest-control story into something almost difficult to imagine.
Seven hundred pounds is far beyond the amount most people would associate with a single bird's food-storage behavior.
According to accounts of the discovery, the enormous collection was enough to fill around eight large trash bags.
For Castro, it was unlike anything he had encountered during more than two decades in pest control.
That experience mattered.
Professionals in his field routinely see things hidden from ordinary homeowners: nests in attics, insects inside walls, rodents using crawl spaces, animals finding their way into chimneys, and all sorts of unexpected activity around buildings.
Yet a wall filled with hundreds of pounds of acorns was something different.
