About Indian meal moths

The Indian Meal moth (Plodia Interpunctella) have a length of their bodies between 8mm and 10mm at rest and between 18mm and 20mm when their wings are spread. The wings are reddish-brown colour at the tips and grey-yellow at the base. The size of the mature larvae is about 12.5mm. The larvae have brown-black heads with elongated off-white, tinged pink or light green bodies. Until reaching pupation, the larvae can moult between four and seven times. The pupae are reddish-brown and are 8mm to 10mm in length. The eggs are between 0.3mm and 0.5mm and usually vary in colour between grey and off-white.

The adult female moths lay between 60 and 300 eggs around or inside stored products. It can take between 2 days and 2 weeks for the eggs to hatch and for the larvae (caterpillar-like) to start spreading around. They start feeding immediately, webbing the food they feed on. It is the larval stage that is considered the ‘pest-stage’. Depending on the conditions available, this stage can last between 2 and 41 weeks. Pupation is done in cracks and crevices and usually away from the food source, often in the area between the ceiling and the wall or on top of the cupboard, where they form a silken cocoon for the pupation. The adult Indian Meal moths come out of these same cocoons when they reach maturity. The whole life cycle of this pest takes between 4 weeks and 43 weeks. Depending on the temperature, there can be up to 5 generations per year. The Indian Meal moth does not like colder climates and if such is present, the larval stage lasts during the whole winter and pupation happens in March with the adult moths appearing in April. In general, colder climate extends the life cycle of the pest.
