Quick answer
How to read this evidence
Cockroach droppings often look like black pepper, coffee grounds, or dark smears. If they reappear near cabinets, sinks, drawers, food storage, or appliances, hidden roach activity is likely.
Confirm by checking
- Black or brown specks, smears, or small pellets near food and water
- Activity around cabinet hinges, appliance motors, sinks, and drawers
- Egg cases, shed skins, odor, or sticky monitor captures nearby
- Droppings that return after cleaning
Do not confuse with
- Mouse droppings are larger and more rice-shaped
- Termite frass forms dry pellet piles near wood openings
- Coffee grounds or food debris do not keep reappearing in the same hidden paths
