What Are These Strange Black Dots in Your Kitchen?
If you start noticing strange black dots in your kitchen or around your home, it's important to understand what they might mean.
A mom recently asked this exact question in a Facebook cleaning group after noticing mysterious black marks appearing around her house. Unsure of what they were, she posted photos and asked other members for advice.
“Does anyone know what this is?” she wrote. “It recently showed up on the baseboard in my dining room, and I've also seen small spots on the wallpaper and the floor—even though I mop every day! It's not raised, and it looks like paint splatter, but it isn't.”
The response from group members was almost unanimous: spider droppings .
Experts who study household pests explain that spiders don't produce solid waste like many other animals. Instead, their droppings are thick and liquid, often resembling tiny dark ink stains. These marks may appear on walls, ceilings, baseboards, or other nearby surfaces.
Unlike pellet-shaped droppings, spider waste usually appears as small stains, spots, or drips. Different spider species can leave droppings that vary slightly in color and texture, which can make them difficult for non-experts to identify.
Spider droppings often collect beneath their webs, especially in corners where cobwebs form. Because spiders prefer dark, quiet areas, their droppings may show up in unexpected places. The spots are usually about the size of a pinhead and can appear black, white, gray, or brown.
