Meal Moths are also known as weevil moth, pantry moth or grain moth. The species was named after being noted for feeding on Indian meal or cornmeal and it does not occur natively in India. The larvae of this species have the ability to bite through cardboards, plastic so even sealed containers might be affected. Moths are difficult to eradicate. The species can reproduce on clothing and any source of clothing must be inspected to prevent second infestation. Adult Indian Meal Moth can reach up to 10mm in length with 15-20mm wingspans. Their wing colour is generally reddish-brown, but they also could be dark grey.
The Indian Meal Moth eggs are very small and white and it is very difficult to see them. The newly hatched eggs are also hard to notice. They can feed on different plants based food like grains, dry pet food, birdseed, cereal, soup mix, pasta, bread, dried fruit, nuts, pasta, rice and flour. Indian meal moth is also known to cannibalize larvae.
Usually, the lifecycle of the Indian Meal Moth colony starts in a place where grain is present. Their eggs are greyish white. The eggs are laid directly on the food source in groups between 10 and 30. A female moth can lay between 200-300 eggs at a time.
Larvae begin to hatch after two to fourteen days. Newly hatched larvae feed on grain while the mature larvae are feeding on grain germ. The adult moths can be seen on the walls of grain bins. Their entire lifecycle ranges between 30 to 300 days. As a matter of fact, seven to nine generations of moths can live in a year.
