Yes, the pin wheels seem to be working.
Pin wheels, what are they doing on the side of the house?
Keeping the woodpecker away!
You can see my prior attempts to fill in his holes didn't prevent him from returning. The sheet of plastic kelt him away from that section and enticed him to go higher.
The pin wheels went up last weekend. I filled in all the holes and inspection this morning in good light shows no sign of any new holes.
We also haven't heard him but since we're both working, we would only hear him on the weekend. So far so good!
One on the other end of the house seems to be doing the trick there too!
