What Are Stored Product Insects ?

Stored product insects are a group of pests that infest and feed on stored food products. They can cause significant damage to food supplies and contaminate them with their bodies, faeces, and larvae. These insects are commonly found in homes, food processing facilities, and storage warehouses throughout the UK.

These pests are a common problem in North London homes and businesses, including grocery stores, restaurants, food storage facilities, and anywhere else that people handle or store food. These pests tend to breed rapidly, allowing for a few to quickly turn into a large infestation that is difficult to control. Businesses that handle any kind of cereal, grain or dried food products are at high risk of infestation from stored product insects.

Stored Product Insects are considered the world’s most expensive pest because they cost businesses billions annually in additional operating costs and loss of product.

Businesses Susceptible to Stored Product Insects

Stored Product Insects are a common problem for businesses that handle or store food, grains, or other dried goods. Here are some of the main types of businesses affected:

Food Industry

  • Food manufacturing and processing plants: These include bakeries, mills, cereal manufacturers, chocolate factories, and other facilities that process raw materials into food products.
  • Food storage and distribution warehouses: Businesses involved in storing and distributing food products, such as wholesalers, importers, and exporters.
  • Retail food stores: Supermarkets, grocery stores, and convenience stores are at risk, especially if they have inadequate storage conditions.
  • Restaurants and catering establishments: These businesses handle large quantities of food, making them potential breeding grounds for Stored Product Insects.

Other Industries

  • Pet food manufacturers and distributors: Similar to human food, pet food can be infested with Stored Product Insects.
  • Agricultural businesses: Grain stores, feed mills, and farms that store large quantities of grain or other crops are susceptible.
  • Pharmaceutical industry: Some insects can infest medicinal herbs and spices used in pharmaceutical products.

Essentially, any business that handles or stores dried goods is at risk of a Stored Product infestation. They can cause the recall of products and the expense involved in issuing a recall, plus discarding infested or damaged products, is very high.

Signs of Stored Product Insects

  • Damage to packaging and products is a red flag, for example, weevils leave visible exit holes in grains and moth larvae have chewing mouthparts, which they will use to cause damage to food and packaging.
  • Moth larvae will also leave webbing, which they will spin as they feed and move through products. The webbing not only contaminates products but can also cause considerable damage to machinery and equipment.
  • Stored Product Insects will cause food to ‘taint’, which is visible as discolouration.
  • Grain that is infected tends to become warmer which can lead to damp, mould and even grain germination
  • Track marks in dust or flour from adult insects is also a giveaway.
  • Frass is the excrement of insect larvae and is another common sign of an infestation.
