Pantry Moth Reproduction

The pantry moth life cycle consists of four stages of development: egg, larva, pupa and adult. Depending on temperature and environmental conditions, the life cycle of a pantry month can range anywhere from a few weeks to nearly a year.

Adult female moths deposit about 300 eggs in or near the food source that will be consumed by the larvae. Eggs are extremely small — about one- to two-hundredths of an inch and are off-white in color. It takes about a week for an egg to hatch into a wormlike larva that is about a half inch long with five pairs of legs. The larvae feed and develop over six weeks, leaving behind a trail of silk and waste as they crawl away from the food source to pupate. Pupae pantry moths build a cocoon in cracks or crevices of the cabinet for two to three weeks until they emerge as winged adult moths.

Adult pantry moths have only one mission — to mate. Since they do not feed, they only live for a week or two. But in that time, hundreds of eggs will be dropped and the cycle continues.
