Hi, I found this answer at pioneerthinking.com:
Termites are a menace to North American homes and are often found in older homes. Hopefully, you'll notice an infestation of termites in your home before they reach your furniture.
The termite solution? Professional fumigation is the best remedy.
The wood beetle is a nasty archenemy of European antiques. It's not as common in North America. Nevertheless, you want to be aware of the wood beetle in case you bring an antique from overseas into your home and infest the rest of your furniture.
The wood beetle lays its eggs in the crevices in wood; the larvae hatch and eat their way through the wood creating a series of tunnels. As the beetle ages, it digs its way out of the wood leaving a hole, flies off to lay its eggs and continues its life cycle.
A tell tale sign that you have wood beetle is the pile of frass (wood dust and insect excrement) on the floor. Another sign of a serious infestation is to pick up an item; if it is very light, likely a large portion of the inside has been eaten away.
How to rid your furniture of this pesky insect? Isolate the infested object. Ensure that the infestation has not spread. Hope that this infestation happened during the winter because the easiest way to get rid of this bothersome bug is to place the item outside on a dry sub-zero day.
I hope that this helps,
Bob
