Do ladybugs eat dust mites

No, ladybugs do not eat dust mites since their primary food sources are aphids, a garden pest. Dust mites are too small to eat and to see with the human eye. If you see dust mites, you are seeing many of them together. Dust mites exist to clean up what falls off from one's body, food scraps, pets and other small matter, so you will always have dust mites in your home.
