Bay leaves in every grain container! Works better than any electric gadget. Modern zappers are just expensive night lights for these moths.
@Jurgen-strangmann Is correct - moths fly differently. Their erratic 5cm flights between shelves won’t reach a zapper. They live and die in your flour, not mid-air.
I now store all dry goods in glass jars with silicone seals. Beautiful pantry display AND no moths for 3 years running!
UV zapper caught 0 pantry moths but 47 other insects. Confirms they’re food-motivated. Great demo for students about pest behavior differences!
