OK, I remember reading somewhere on the forum (can't find it again) over the last few days about the 1mm sized holes and little piles of wood-dust being caused by borer beetles.
Well that's exactly what I have in my built-in office cupboard. It's in the end of a 20x38mm strip used to support a melamine shelf.
What's the treatment ?
Do I rip it out and replace the brace and the shelf ?
Do I need to remove all wood from the cupboard ?
A bit concerned as I have 130 square meters of Kiaat parquet flooring and I don't want to lose it - I love the natural wood floor.
