These are insect pests which are found in or associated with food products. This group covers a large number of insects. They can infest a variety of stored products including grains, cereals, dried fruit, nuts, seeds and tobacco.

The five major Stored Product Insect (SPI) Pests

  • Drugstore beetle
  • Flour Beetle
  • Saw Toothed Grain Beetle
  • Indian Meal Moth
  • Fruit Flies

Stored product insects are a health hazard in both private homes and in business where the economic losses through damage and contamination of food products can be very significant.

Any contamination of Stored Product Insects or their by-products will make your food unfit for human consumption.

Businesses like food processing or grain storage are strongly advised to employ a pest management program to contain and eradicate infestations, along with high standards of hygiene and sanitation, including stock rotation practices.

In the home, discovering pests in your food stuffs can be distressing. Owing to the risk of contamination they will most likely spoil and damage any food they come into contact with. It is important to be able to identify the earliest signs of a problem to enable a quick solution and a guaranteed control measure which prevents a re-infestation.

  • Stored grain
  • Dried fruits
  • Milled and processed cereal products
  • Sweets
  • Cheese
  • Meat and any other dried food
  • Dry ginger
