Female moths will mate and lay up to 400 tiny eggs at a time, ideally near a source of food.
The eggs will incubate for up to eight days and then hatch.
The tiny emerging larvae then begin to eat whatever they find (flour, cereal and animal-based fabrics are particular favorites depending on the species).
After about 14 days of continuous eating, the now-larger larvae spin tiny cocoons for themselves in dark corners or even inside food containers or clothing.
Two weeks later, the adult moths hatch.
At this point, the cycle begins all over again, and can happen up to six times in the average year.
