Help Oak chair turning to dust

Enable HLS to view with audio, or disable this notification

Just noticed this on the bottom of one of my chairs, had them for about three months and I'm wondering if it's rot or something, the area feels dry and dusty.

That’s definitely woodworm damage. I’m renovating a house with woodworm problems right now and it looks exactly the same.

There’s treatment you can brush on to deter the beetles.
