What environmental factor, besides food presence, defines the moth's location density?
Answer
Lack of disturbance near that food source
While the availability of organic food sources is fundamental to establishing a colony, the success and density of the White-shouldered House Moth population are critically linked to consistent environmental stability. Areas that are regularly cleaned, dusted, or exposed to significant physical movement lead to a sharp drop in population, even if food remains present. Conversely, spots that experience intermittent, light cleaning, such as the back of a utility closet or seldom-used storage areas, become highly prone to infestation. The constant lack of disturbance near accessible food allows larvae to feed, develop, and pupate without interruption, fostering a stable, hidden colony.
