Pests like pantry moths are of no use to the household, however, the fact that they are not harmful to humans is a relief. Neither the phylum Lepidoptera, to which the pantry moths belong, nor any of its insects, larvae or eggs are carriers of human diseases or producers of toxic substances. The intake of the pantry moth larvae or the pantry moth eggs is generally safe when it is accidental, although it is not at all attractive. The major danger lies in food contamination- pantry moths and their leftovers (webs, feces, exoskeletons) can spoil food, causing it to wasted and possibly with bacterial contamination if the infested food goes unnoticed.

Getting to know the life cycle of pantry moths is very important because it is the first step to end this unwanted cycle. Here is its step-by-step process:

  1. Pantry Moth Eggs: The female moths spread their 100-300 barely visible microscopic eggs through food like wheat, flour, and cereal. These eggs are very small in size, so we can’t easily detect them, and due to which leads to the infestation.
  2. Pantry Moth Larvae: After a few days, pantry moth lay their eggs and covert themselves into larvae stage, and they are small in size and called the white caterpillar. The pantry moth larvae are the biggest source of problems as they consume what you store, cast cobwebs, and become a source of pollution for your food.
  3. Pupa Stage: Once the pantry moth larvae are fully fed, they get out of the food source and seal themselves in cocoons in the cracks or gaps where they pupate. The larval stage usually stretches for several weeks.
  4. Adult Moths: Adult kitchen moths fly out from their pupa cases, start mating, and the life cycle repeats. Adults usually survive three weeks or one week only from the emergence time, but the total life cycle can be as short as 30 days in tropical areas and up to 10 months in cooler places.
