He Smelled Something Strange in His House, Then Opened the Wall and Found This

After more than two decades in the pest-control business, Nick Castro had learned that houses can hide some remarkable surprises.

As the owner of Nick’s Extreme Pest Control in California, Castro had spent years investigating the kinds of problems most homeowners would rather never encounter. Animals could squeeze into spaces that seemed impossibly small. Insects could establish colonies behind walls without being noticed. Strange noises coming from an attic could turn out to have an explanation very different from what a homeowner initially imagined.

After more than 20 years on the job, there wasn’t much that Castro believed could genuinely surprise him.

Then he received a call involving a woodpecker.

At first, the problem sounded relatively ordinary. A homeowner had noticed that a woodpecker was repeatedly drilling holes into the exterior  siding of the house.

The visible damage was frustrating, but nothing about it suggested what was happening on the other side of those walls.

The  bird wasn’t simply pecking at the house.

It was using the structure for storage.

And by the time the wall was opened, the scale of what had accumulated inside was enough to astonish even an experienced pest-control professional.

It Began With Some Suspicious Holes

From outside, the first signs of the problem didn’t look particularly dramatic.

There were holes in the home’s siding, apparently created by a woodpecker that had taken an interest in the property.

Woodpeckers peck at wooden surfaces for several reasons. Depending on the species and situation, they may be searching for insects, communicating, creating nesting cavities, or storing  food.

In this case, food storage was the key.

The bird had been collecting acorns and pushing them into holes in the home’s exterior.

An acorn here or there would hardly have been remarkable. Even several dozen might have seemed like little more than an unusual inconvenience.

But the design of the house created an unexpected problem.

The holes didn’t function like shallow storage spaces.

Instead, they provided access to the hollow cavities behind the siding and inside the walls.

When the woodpecker inserted an acorn, gravity could pull it farther down into the structure.

The bird could then return with another acorn.

And another.

And another.

From the outside, all anyone could see were relatively small openings.

Inside the walls, however, a hidden collection had quietly been growing.
