The Real Explanation
- Carpet beetles
- Termites (especially drywood termites)
- Cockroaches
For example, termite droppings—also called frass—often appear as tiny, hard pellets that can resemble grains of sand or pepper. They’re typically found in small piles near wood or hidden crevices.
Carpet beetle larvae, on the other hand, can leave behind small debris that looks similar and tends to collect in bedding, fabrics, or upholstered furniture.
Why They End Up in Your Bed
- Nearby furniture or wooden structures may be infested
- Bedding can trap debris from the surrounding environment
- Open windows or poor sealing can allow insects to enter
Your bed isn’t necessarily the source—it’s just where the evidence ended up.
