Stored Product Insects

There are many types of stored product insects (SPIs), which are often found damaging and contaminating raw materials used in food at home or in businesses. Worldwide, storage insects damage up to 12% of grain production every year. Some common foods infested by these pests include grains, cereals, dried fruits, and seeds. These tiny pests can easily seep through the small gaps between packaged products.

These pests pose a health hazard to both homes and businesses such as food processing plants, restaurants, and stores. They can cause enormous economic losses through their damage and contamination of food products. These damages can occur from the moment the grains are harvested all the way to when consumers serve them as meals.

Identifying and removing the source of the infestation is a critical part of effectively controlling these pests. Businesses like food processing or food storage facilities can greatly benefit from an ongoing professional integrated pest management program for effective and long-term protection against grain beetles.

Signs of Stored Product Insects

Stored product insects are so small that you may not notice a problem at first. Always look out for the following tell-tale signs that indicate the presence of these pests on your premises. They are commonly found in food storage areas, beams, windowsills, food processing machinery, packaging, and food products.

• Damage: Can be found on raw materials and foodstuffs.
• Live or dead weevils: Emerging and leaving visible exit holes in grains.
• Infected grain: Will appear damp, mouldy, and may even start germinating in warmer conditions.
• Floury dust: Created as adults move from one food source to the next.
• Moulded goods: Insects such as flour and grain beetles can cause discoloration of goods and make them prone to moulding.
• Holes in packaging: Inspect for any cracks and gaps between packaging.

Stored Product Insect Control

Any business that handles cereals, grains, or dried food products is at risk of an SPI infestation. There are many different species of insects, particularly beetles, that can damage raw food materials and contaminate finished products, making them unfit for consumption.

Leaving an infestation untreated can cause severe loss of valuable stocks and further damage your business's reputation, resulting in a loss of trust in the brand. Implementing a professional integrated pest management program can help protect against these pests and ensure the quality and safety of your food products.
