Can someone help? I have been researching this myself and cannot seem to come upon a definitive conclusion. I have been finding small piles of brown "beads" that look like coffee that has been ground VERY FINE. These pile have been at the base of the frontdoor sidelight (interior and exterior -- on porch). There is a small hole in the ceiling above and they are sprinkled above the transom, which means the "droppings" came from above.

They are also "sprinkled" on a piece of furniture upstairs -- again meaning that they came from above. Our house was built in 1895, Balloon Construction, 1 1/2 story house. Tented about 11 years ago by previous owner (bond has expired). At first, exterminator said Powder Post Beetles, but after taking the "evidence" to the entamologist, they say Dry Wood Termites and the we need to TENT. Advice? Opinions? Thanks!
