Where might *Endrosis sarcitrella* larvae develop within hidden void spaces inside a structure?

Answer

Wall cavities, under floorboards, behind loose baseboards

The larval stage, being the destructive phase, seeks out dark, sheltered crevices that accumulate dust, lint, and detritus. Inside structures, these conditions are perfectly met within wall cavities, the spaces found underneath floorboards, and areas behind loose baseboards where materials accumulate undisturbed. These locations mimic the sheltered, dark recesses found in nature that the species prefers for development. Finding the larvae in these void spaces indicates a long-established, hidden colony, as these areas are rarely subjected to cleaning or disturbance, providing the necessary stability for their multi-month lifecycle.
