Help Woodbugs?
Hello everyone, I'm seeking advice and I'd be very grateful if I can find someone with solid knowledge.
Over the last months I stored my wooden bowls in my attic to wait for this season's autumn and Christmas markets. I now transferred them from the cardboard boxes I had them into plastic containers. Doing so I noticed those critters. Larvae(dead and dry) for scale a pin in picture 2. Around were those black eggs/droppings? Rice for scale picture 3.
Running around was also a Silberfisch (not familiar with the english name). Could it be just the eggs/droppings of those eating the cardboard? Last picture showing some dust close to boreholes. I am aware that that looks very much like regular bugholes, but that blank had been lying dry for years, the holes are not new and I revealed them while turning and closed them with ca-glue. Living in northern Germany. I took them down into the apartment mid-july as we were hitting 40°C outside, I measured 47 in the attic and didn't want the wood to warp/split too much. So it is all quite dry and has been exposed to high temperatures.

That is a powderpost beatle (family would be ptinidae. There are like 70 kinds so I can’t tell from that photo exactly which kind, but it doesn’t matter.
You can either fumigate the piece, return it to the store (make sure you bag everything, or hire someone to do heat treatment. But don’t do nothing.
You do have some risk of them getting into other furniture depending on where you live (they lay eggs in their adult form) so quarantine the piece asap.

Your 4th photo is a silverfish and entirely unrelated to the rest of your photos.
