Asian lady beetles seek shelter in homes as winter approaches

As winter approaches, Asian lady beetles are seeking shelter in homes, unlike native ladybugs that hibernate under tree bark. These beetles are harmless and help control aphid populations, which can damage plants. Asian lady beetles can enter homes through cracks and openings, especially on south-facing sides. They emit a pheromone that attracts more beetles once a few have entered. They do not breed indoors and will leave in spring. To manage them, homeowners can vacuum the beetles or seal entry points. Pesticides are not recommended indoors, as they do not harm the beetles in walls or attics.
