What Are These Strange Black Dots In Your Kitchen

Editoron

What’s accurate

  • Spiders do produce droppings. Unlike mammals, spiders excrete nitrogenous waste in a semi-liquid form, so their droppings often look like small dark splatters, drips, or ink-like spots rather than solid pellets.
  • The stains are often found beneath webs or resting places. If you notice repeated spots directly below a spider’s web or favorite hiding place, spider droppings are a reasonable explanation.
  • Cleaning doesn’t solve the underlying problem. Removing the stains won’t stop new ones from appearing if spiders remain in the area.

What’s less certain

The Facebook group’s conclusion that the spots were definitely spider poop is too confident.

Similar black spots can also come from:

  • Fly specks
  • Cockroach droppings
  • Small beetles or other insects
  • Mold or mildew
  • Paint splatter or other household stains

Without examining the stains, it’s impossible to identify them with certainty from a photo alone.
