Carolyn –

Those dots on the squares are parasitized moth eggs with developing trichogramma inside. The trichogramma wasps will emerge from the eggs too seek out and destroy the immature pantry moth. The dots on the squares will remain after the trichogramma hatch. However, if you look closely — using a magnifying glass or lens — you will see a tiny exit hole in each egg where the tiny trichogramma emerged.
