Pests that are typically found inside cupboards in dry, stored food are commonly known by the term “stored product insects” or “stored product pests”.
They vary in size, shape and colour, but all have one thing in common – they are tiny, infest, mate inside of and feed on dry stored food resulting in monetary loss, food spoilage and an infestation; potentially devastating to industries such as restaurants, retail and manufacturing.
In an office environment, people often keep their cereal, coffee, powdered milk, crackers, chocolate and snacks inside their drawers and on desks. This could potentially lead to annoying pests getting inside and causing an infestation.
There are many types of stored product pests; however, these are the most common types:

Proper food storage to prevent pests
If your office workers and staff don’t store their dry food correctly, then there is a chance that you may be facing an infestation sooner or later.
Dry food products should be stored inside clean kitchen cupboards in food-safe plastic or glass containers with air-tight lids. The emphasis is on the air-tight lids, which will prevent pests from getting inside, and if they do, this works well as a containment measure.
If dry food products are kept inside of desk drawers, they should always follow the same rules, and either be kept inside a plastic container with an air-tight lid or a Ziploc plastic bag.
If you find contaminated food, immediately dispose of the food in a sealed bag and disinfect the area. Another great prevention tip is to dispose of the container where the infestation or pests were found.
Use specialized pesticides to treat infested areas. However, we would highly recommend that you use a professional pest control service to ensure the source is found and an infestation is completely eliminated throughout the building.
