Pantry Pests Control

The Indian meal moth, Plodia interpunctella, is the pantry's most common invader: a small moth with coppery bronze wingtips that arrives inside grocery packaging as eggs or larvae and then breeds in flour, cereal, rice, pet food, birdseed, and dried fruit. The larvae do the damage, spinning fine silken webbing through dry goods and leaving frass that ruins the whole box. They share the shelves with sawtoothed grain beetles, flour beetles, and weevils, all of which hitchhike home from the store rather than invading from outdoors. One infested bag of bulk-bin granola can seed every open package in the pantry within weeks, and the moths themselves flutter at dusk, which is usually when homeowners first notice the operation is underway. Pheromone traps confirm the species, but traps alone never end it: the fix is finding every infested product, because a single overlooked bag restarts the whole cycle.
