Spikes causing coating damage are surely unknown. What was really surprising was what Mark found when unscrewing the insulation. Suddenly the holes all made sense.
Boring woodpeckers used the pool as a food supply. Inside, Mark found thousands of acorns that the woodpeckers had hidden.
Mark thinks the woodpeckers were making holes in an attempt to hide the acorns later. However, the birds did not realize that the walls were hollow and so they would lose their food hidden in the insulation.
Apparently the woodpeckers weren’t smart enough to spot flaws in their ways and kept dropping their food on the walls.
The best part of the video is Mark’s amazement because the nuts keep falling. It is truly amazing to see the huge amount of acorns these woodpeckers manage to lose in the walls of the pool house.
