Pantry pests are more common than most people think. These include weevils, small beetles, and moths that are naturally drawn to dry food items like flour, rice, and grains. If you have ever noticed tiny bugs in pantry shelves or containers, chances are they came from one of these sources.
These pests can enter your kitchen in different ways. Sometimes, they are already present in packaged flour as eggs that are not visible to the eye. In other cases, they come from nearby infested items and spread across your pantry. Warm and humid conditions make it easier for them to grow and multiply.
Once they get access, they settle into open or loosely stored flour and start reproducing. That is why storage plays a bigger role than most people expect.
