In heavy infestation the surface of the entire stock can be covered by silken webs left behind by the wandering larvae.
The tropical warehouse moth feeds on a range of stored foods, notably cereals and cereal products. Although the amount of sperm produced by males decreases across subsequent copulations, this appears to have no effect on the number of eggs laid and offspring hatched by the female.

Up to eggs are laid in the first days of their short day lives. Low temperatures delay oviposition, and low humidity or lack of access to water seems to reduce the number of eggs oviposited by any given female.
Incubation period is days only. Like the raisin moth, the almond moth has achieved an essentially cosmopolitan distribution due to inadvertent transport with ephrstia products in its larval form.

Larval growth and rate of development depends on temperature.
