What is the most effective treatment method for flour beetles that infest milling operations?

The most effective treatment method for flour beetles that infest milling operations involves using crack and crevice treatment near food storage areas. This approach targets the locations where flour beetles are likely to hide and breed, as these insects often prefer dark, narrow spaces near their food source. By applying targeted treatments within these crevices, pest control professionals can effectively eliminate beetles while minimizing the impact on the larger environment, including areas used for food storage and processing.

While sealing food products tightly is an important preventive measure, it does not directly address an existing infestation. Likewise, treatment with bait stations may not be as effective since flour beetles primarily feed on flour and other dry commodities, which makes it difficult for them to ingest bait. Heat treatment can also be effective, especially in extreme infestations, but it may not be practical in all milling operations due to equipment limitations and the risk of damaging product quality. Therefore, utilizing crack and crevice treatments is identified as the most strategic approach in managing flour beetle infestations in this specific context.
