? Furniture Bugs?

[descodave]

We bought some rattan furniture at Island Collections in Kona about 3 years ago, & just recently we're seeing some small slightly oblong tan colored wood shavings or maybe droppings on the floor under the arm area of the sofa bed. We flipped the couch over & can't see anything; I clean up the area, but then the little pile comes back! Anyone know what this could be & how to stop it? Thanks for any help.
