Mill moth infestation
The Mill moth originates from India and was first introduced in Europe in about 1877. Since then, it has been a popular pest in flour and both homes and business premises have suffered the presence of the Mill moth infestation. Nowadays, however, it is mostly considered an industrial or commercial pest as it is not often found in households.
This moth is most often found in flour, corn and gout mills, bakeries, and other businesses dealing with these products. Also nuts, cocoa, seeds, dried fruit, cereals and grains.
Signs of Mill moth Infestation are solid lumps of food particles in the stored products as a result of the larvae entwining everything that they feed on, grey or brown colouring of the product, due to the Mill moth faeces and webbing covering the food particles.
The Mill moth is not considered dangerous to people or pets, however the damage it does to the stored products renders them unfit for purpose and they should be disposed of.
Mill moth treatment and control
As with all other stored product insect, the general best practice for Mill moth infestation prevention is good housekeeping and regular checks of the stored products. This way any early signs of the infestation can be spotted and it may be controlled and eradicated quickly. However, if a Mill moth infestation has developed then the best treatment would be fumigation of the infested area combined with an insecticide treatment of all associated cracks and crevices, where the moths can settle or hide.

About mill moths
The Mill moth (Ephestia Kuehniella) is similar in size to the Indian Meal moth – 7mm to 9mm in length at rest and 15mm to 20mm with spread wings. The visible difference between the two pests is that the Mill moth has a zig-zag-shaped black pattern across its grey-coloured wings. This pest is found worldwide and prefers countries with average temperatures 20C to 25C.
The adult female Mill moth can lay up to 562 eggs in or around its food source. Once the eggs hatch, the larvae (caterpillar-like, grey to ochre-yellow colour) start feeding around and producing silk and webbing the food around. The silk can create significant nuisance in wheat mills as it can obstruct the machinery and become an undercover for various insects, pests in different grain products. The pupation of the larvae happens in the same product that they have been hatched in. Once they reach maturity and turn into adult moths they live for only about 14 days, mainly flying around roofs and being active in the early hours of the day and the late afternoons. In optimal conditions the life cycle of the Mill moth is between 43 to 72 days.
