- Small reddish stains on sheets
- Blood spots on pillowcases
- Marks on pajamas
These can occur if a bedbug is accidentally crushed after feeding.

3. Dark Specks
Bedbug droppings appear as:
- Tiny black dots
- Ink-like stains
- Small dark smears on mattresses or furniture
These are one of the most reliable signs of an infestation.
4. Shed Skins
As bedbugs grow, they shed their outer shells.
Finding pale, empty skins around mattress seams or furniture is another clue.
5. Live Bedbugs
Adult bedbugs are visible without magnification.
They often hide during the day and become active at night.
How Do Bedbugs Spread?
Bedbugs do not jump or fly.
Instead, they spread by hitchhiking on:
- Luggage
- Clothing
- Backpacks
- Used furniture
- Mattresses
- Boxes
- Bedding
They can also move between apartments through wall openings or utility lines.
Having bedbugs is not a sign of poor hygiene. Even very clean homes and hotels can become infested.
Can Bedbugs Make You Sick?
Current evidence indicates that bedbugs are not known to transmit diseases to humans under normal circumstances.
However, they can still cause problems such as:
- Itching
- Skin irritation
- Allergic reactions
- Sleep disruption
- Anxiety or stress
