What is a common sign of pantry moth infestation?

The presence of moths flying around is indeed one of the most recognizable signs of a pantry moth infestation. These moths, particularly the Indian meal moth, are often spotted fluttering in proximity to food storage areas as they search for food sources to feed upon. Their flight pattern often indicates their presence and can prompt further investigation into potential infestations.

The other options, while they may relate to pest infestations in general, specifically lack the direct connection to pantry moths. For instance, webbing in food storage areas is indeed a sign linked to pantry moths, where larvae create silken webs around food sources, making this an important indicator of an infestation. An odor of decay could indicate many types of pest problems, but it is not specifically associated with pantry moths. Lastly, having all food containers opened might suggest activity but isn't a definitive sign of their presence on its own; moths may infest sealed packages as well.

In recognizing the presence of flying moths, one can quickly identify a potential issue and take appropriate measures to address the infestation, such as inspecting food storage areas and implementing control measures.
