Which life stage of the White-shouldered House Moth is characterized as the destructive one indoors?
Answer
The larval stage
The key to understanding the impact and location of the White-shouldered House Moth within a human dwelling lies in identifying the destructive phase of its lifecycle. The adult moths are primarily seen as a nuisance, often noticed flying near lights after dusk, but they do not cause damage to materials. The actual consumption and destruction of stored products and natural fibers—grains, wool, silk—is carried out exclusively by the larvae. Because the larvae remain active and feeding for several months, their location dictates where material degradation occurs, making larval control the priority for effective management.
