Stored Product Insects
Stored product insects are pests that infest food items stored in homes, warehouses, and commercial establishments. These insects can cause significant damage to food products and lead to economic losses if not managed effectively.
Species Commonly Found in Singapore

Almond Moth (Cadra cautella) are similar in appearance to the Indian meal moth and primarily infests nuts, dried fruits, and cereals. The larvae can cause contamination and spoilage, making it essential to monitor stored food items regularly.

Indian Meal Moth (Plodia interpunctella) is recognisable by its distinctive two-tone wings, the Indian meal moth is a common pest in pantries and kitchens. The larvae feed on a variety of grains, dried fruits, and processed foods, leaving behind webbing and frass (insect droppings).

Cigarette Beetle (Lasioderma serricorne) is a small brown beetle that infests dried food products, particularly tobacco, but can also be found in spices and dried herbs. Their presence can lead to significant losses in stored food items.

Flour Beetle (Tribolium spp.), including the red and confused flour beetles, are common pests of flour, grains, and cereals. They can reproduce rapidly in stored products, making timely intervention crucial for management.

Sawtoothed Grain Beetle (Oryzaephilus surinamensis) are recognisable by their serrated edges, these small beetles are known to infest a wide range of stored grains, including rice and flour. Their presence can indicate poor storage practices and can lead to contamination.

Foreign Grain Beetle (Ahasverus advena) is a small, dark brown beetle that infests a variety of stored grains and products. They can be found in both commercial and residential settings, making effective control essential.

Rice Weevil (Sitophilus oryzae) is a serious pest of stored rice and grains. Characterised by their elongated snouts, they can infest entire bags of grain and lead to significant losses if not controlled.
Stored product insects (SPIs) like Indian meal moths, flour beetles, and rice weevils are commonly found in places where dry food is stored. They often infest pantries and kitchen cabinets, targeting items like grains, flour, dried fruits, and pet food. Their larvae can contaminate food with webbing, droppings, and unpleasant odours, often going unnoticed until the damage is done.
In businesses, mainly in restaurants, grocery stores, food factories, and warehouses, SPIs can cause serious issues. Infestations lead to product spoilage, inventory losses, and damage to reputation. If left untreated, they may result in failed health inspections, fines, and even temporary closures. Keeping food storage areas clean and pest-free is critical for food safety and customer trust.
If you spot SPI in your pantry inventory,
Avoid using or consuming any affected items, as they may be contaminated. Do not move infested products around, as this can cause the pests to spread. Instead, contact a professional pest control service to inspect the area, identify the source, and carry out proper treatment to prevent further contamination and protect your food supply.
