What characteristic enables *Endrosis sarcitrella* to maintain its status as a common household insect worldwide?
Answer
Capability to develop well on low-grade accumulated dust
The widespread success of *Endrosis sarcitrella* stems directly from its remarkable adaptability, particularly the larval ability to survive and develop on very low-quality sustenance. The capacity to subsist on common household waste, such as accumulated dust, lint, and dead insect remains, means the insect requires very little in terms of easily accessible, specific resources to maintain a viable population. This low nutritional threshold makes complete eradication difficult without thorough sanitation of all hidden areas.
