It looks like you might have forgotten to include or attach a photo! Could you please describe what the piles look like (e.g., color, texture, shape, where exactly in the room you found them, or whether they look like dirt, dust, insect droppings, or toys/craft supplies)? Alternatively, if you are able to upload or share a picture, that would make it much easier to tell you what it is!

Yes—please upload the photo if you have it. I can examine it and help identify what the piles appear to be.

If you can’t upload a picture, tell me:

• Color: brown, black, white, tan, etc.

• Texture: powdery, sandy, pellet-like, sticky, fibrous, etc.

• Shape/size: tiny dots, pellets, clumps, flakes, or larger pieces.

• Location: floor, wall, windowsill, under furniture, near food, etc.

• Anything nearby: insects, holes, damaged wood, spilled materials, toys, or craft supplies.

With those details, I can narrow down the possibilities.
