I have a small problem with a woodpecker that wants to build a nest under my yawning at the log house. My management company asked about a woodpecker deterrent additive you can add to a paint or stain? This isn't sold in Japan and I do not think reflective tape and stuff really works.

I know BreakGuard in the US, but that is acrylic and comes in colors which doesn't help me since I need a natural wood stain.

Anyone know of a product or tried and true method to discourage woodpeckers?

I plan to have bird boxes installed on the far corners of the property to encourage nesting there.

This is not looking for insects, this is nest building.
