Warehouse moth infestation

Warehouse moth treatment and control London for businesses and residents

The Warehouse moth is very close to the Meal moth but it infests foods like cocoa beans, nuts and dried fruit. It can also infest various flours, cereals, cocoa powder, as well as tobacco. This makes them a very challenging pest for the businesses dealing with these products. The Warehouse moth is considered as serious pest in the tobacco industry, as the Tobacco beetle. When they enter a warehouse, they most often than not go to the raw materials store. If they spread around the factory, they can find food sources in the machinery where there are leftovers from grains and cocoa beans. The infested products are not only rendered unfit for purpose but also can be seats for infection.

Once entered a factory, there is always the risk for the Warehouse moth to lay eggs in the finished product, it will result in it having ‘worms’ (the caterpillar-like larvae of the pest) and will have to be disposed of. The adult moths are not capable of penetrating through packaging, however, they can sense the smell of a product through a very tiny opening, which would lead to the moth laying eggs close to this opening and the larvae will then crawl inside and infest the product.

The signs of Warehouse moth infestation are silk webs over the infested products, as well as damaged nuts and grains and solid lumps within the flours. The presence of the adult moths, which can usually be spotted at night around the roof of the building, as well as the larvae that feed on the products, which can be spotted inside or crawling around the stored products.

Warehouse moth treatment and control

The Warehouse moth is similar to the Indian Meal moth and the Mill moth, as well as to all other stored product insects, when it comes to infestation prevention and control. The best way to prevent the development of such infestation is to conduct regular pest control inspections, which would detect the early signs of a potential infestation and the necessary precautions will be taken, so that it does not develop and spread. Good housekeeping and sanitisation of all areas in the factory or warehouse is also very important when it comes to limiting the conditions for the Warehouse moth infestation development.

Where a Warehouse moth infestation is already present and cannot be controlled, fumigation can be carried out of all affected areas, followed by an insecticide treatment of all associated cracks and crevices, which might serve as a hiding spot for the pest. This will eradicate all life stages of the infestation and will help to completely exterminate it.

About Warehouse moths

The Warehouse moth (Ephestia Elutella) is a popular industrial pest, which infests both food products (flours, cereals, cocoa, etc…) and tobacco. It is grey-brown in colour and is banded with lighter and darker colours on its wings. The length of this moth is 7mm to 9mm at rest and 10mm to 16mm with spread wings. The larvae may be slightly different in colour, depending on their diet – off-white, yellowish or reddish colour.

The adult female Warehouse moth can lay up to 279 eggs. In temperatures above 20C it takes 3 to 6 days for the eggs to hatch and it them takes 10 to 20 days for the pupae to mature at temperatures between 18C and 26C. Pupation can happen immediately in dark and secluded places and maturation can be very quick, however most pupae remain at this stage for a year time, which extends the presence of the infestation. The total lifespan of the Warehouse moth is between 50 and 90, depending on the conditions available.
