Bed bugs leave behind many visible signs on the mattress, sheets, or even the bed frame. Whether it's characteristic marks and stains, droppings, or blood residues, each mark is a sign of infestation. Discover how to identify these traces, clean effectively, and prevent their reappearance.
1. Identifying bed bug marks and stains on the mattress and sheets

The different types of marks

- Bed bug mark on wood and bed frame: Dark stains embedded in the cracks of the bed frame.
- Blood stain left by a bed bug: Result of these pests' feeding or an accidental crushing during sleep.
2. Droppings and signs of bed bug presence
Bed bug droppings are another revealing sign of an infestation. They form small black or brownish dots, often mistaken for mold or dust marks.
