Not an insect (likely biological debris)

Found on surfaces or fabrics within human dwellings

Non-living matter

Based on the image, these items appear to be non-insect debris such as dried skin, scabs, or remnants of food. They lack the defined anatomical structure (segmented legs, antennae, head) of an insect or bug.

There are no inherent risks or benefits associated with these dead biological fragments, though their presence may indicate a need for routine cleaning of the area.
