Are weevils already in flour?

Yes, it's very common for weevils (or their eggs/larvae) to be present in flour from the start, as they can be in the grain before processing or get in during storage; they often go unnoticed until they hatch into visible adults, which can then infest other dry goods if not stored properly in airtight containers.

Are weevils always in flour?

No, not all flour always has active weevils, but it's extremely common for grain products to contain their microscopic eggs, which can hatch into weevils (or other flour beetles) in warm pantries, turning into visible bugs with webbing and a musty smell. These bugs are generally harmless if baked, but you can prevent them by freezing new flour for a few days and storing all grains in airtight containers to keep them out or kill any eggs.
 

How to check flour for weevils?

To check flour for weevils, spread a portion on a white plate to look for tiny, moving brown bugs (weevils) or webbing, and feel for sawdust-like clumps from their droppings; they often emerge in warmer months, but checking new bags and freezing them immediately is key to prevention. Sifting works to separate adult weevils, but the best approach is prevention through freezing and airtight storage to kill hidden eggs, say experts.
 

How do weevils get into sealed containers?

Weevils get into sealed containers because their eggs or larvae were already inside the food product (like grains, flour, cereal) when it was packaged, hatching later in your pantry, or they chew tiny holes through thin packaging like plastic bags to enter.
