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!

Dear 1895Florida,

Howdy,Coach Dave here and I work for The Home Depot and I think I can help answer your "coffee grounds" question.

Unfortunately it sounds like you have Dry-wood termites. The "coffee grounds are fecal pellets are kicked out of the colony by workers.

Your need to take action now to minimize damage caused by the termites. If the infestation is in the early stages various sprays can be used. However if this is has been going on for a long time it may be time to call in an exterminator.

I would remove some of the wood from the area where you notice the most pellets to hopefully get an idea how extensive the damage may be.

If you have anymore questions let me know, I'm here to help.

Yours Respectfully,

Coach Dave

I've been noticing these "coffee ground" looking piles on the floor around my apartment (which is in an old building) too. I am wondering if you ever figured out what insect is responsible for these piles? I went out of town for about a week and a half and just got back and realized these piles are now in four spots around my apartment instead of one. Any advice would be wonderful.

Thank you,

I agree with the reply from Home Depot. You've got termites. You need to call a professional for advice.

What kind of insect lives in the ground and makes a grater about 1 inch wide and 1 inch deep small hole in the center? They are not bees.
only about 1/8 inch in size. And how do I get rid of them????

Thank you

I am having a similar problem. I have tired everything. Clorox, RAID, Baking Soda/Water. It seems this black pile is alive with these litttle bugs (see photo) that keep coming back. I will clean this black pile and literally withing hours its back. I have never seen anything in my life grow so quickly. It seems like waste from these bugs, but how is even possible that these bugs can live and survive the constant cleaning. I am at a loss right now. Its like these things are some sort of alien species living in the silicone sealant. Please help. I dont know what to do. the bugs move very slow but are back every night. No wood this is all on granite and tile counter tops.
Black powder waste

I found about six clumps of these outside today, I accidentally put my hand on a clump and resulted in hundreds of them running all over my hand and arm. Does anyone know what they are? The photo is magnified.

what I have is larger than coffee grounds. It first appears on the ground as orange beads as small scattered piles.The next morning it will be brown. I soil is dry,when touched they will just puff out a little puff of dust and is flattened. What is this?

Sounds like you have a kind of mold. tThe "dust" is most likely,
the spores looking to spread, and proliferate.

I have a similar problem on the ceramic floor next to the baseboard. I clean it and it reappears in a couple of hours. I have seen some small regular looking ants in that area. Picture below. Ideas please!!

That sounds a little like carpenter ants. They start at the bottom then make a hole 90 degrees to the ceiling. The holes come out in the wall, there, not the ceiling. They come out eventually and swarm.

I have a very similar problem but my "black dust and a "burn mark" are only found in storage boxes that have been in a room for a LONG time and under the rug in an outdoor screen room that has windows in place of screens. They are only in two rooms so would a termite only target them? I do not have the problem any where else in the house. I take the tiny piles of black course dust and when removed it leaves what looks like a burn mark that is difficult to clean and take out of a nice box. Thanks for any further help.
