Real wood furniture infested with pests - what to do?

Such an infestation should not happen, but it can occur occasionally. If the other furniture shows no signs of infestation, they are fine as well. Stick to the manufacturer and the line, after all, you didn't choose them without reason and assume that you just had bad luck with a single case. Don't let it drive you crazy.

Do you mean that it skips? I don't think we have an extreme infestation now. Within 2-3 months, a few small piles of flour have accumulated on the glass bottom. Other parts of the cabinet seem fine. The other two cabinets from the line also seem unaffected. We have seen/found exactly one adult beetle. Yesterday it was sitting inside the cabinet, today to my horror outside. My husband photographed it, then we eliminated it.

Actually, there are indications on the internet that something like this can happen when buying furniture. I would have assumed that antiques are more likely to be affected, since appropriate precautions should be taken when manufacturing furniture. If something like this goes undetected, it can end badly. With (very) extreme infestation, you can even hear the bugs "smacking" at rest (at night). No joke. But we are probably far from that here ... :)

I sure hope so o_O

Do you mean that it skips? I believe we don't have an extreme infestation right now. Within 2-3 months, a few small piles of flour have accumulated on the bottom of the glass.

The probability is not high, but the impact in case it happens. I also don't think I will have a car accident, and yet I buckle up. (Statistically, after 30+ years of accident-free driving as a frequent driver, it would be my turn sometime)

Apart from the warranty claim: We have continuous frost here until Monday morning down to minus 10 degrees. If you put the thing outside under such conditions now for 24 hours, the little creature should have caught quite a bit without any chemicals. Then you should be able to place the "post mortem" back inside the apartment with a clear conscience. However, when purchasing a new one, the way of exchange is of course your right - and in the end probably the best solution.

My nightmare with the timber frame house. I also get nervous about every beetle here. But I have also often asked myself whether I am bringing pests into the house with solid wood furniture. How do you prevent that?

With us, there are only solid wood furniture - my whole life long (and that’s been quite a while) ... we don’t take any precautions. If I notice something somewhere (loose, fresh wood dust), I would work with heat, unless the piece fits in the freezer (which unfortunately is already full).

In my opinion, attention should be enough as a "precaution" ...
