Ladybugs
Ladybugs are beneficial outdoors but can swarm inside homes to overwinter.(Coccinellidae) Also known as ladybird beetles, these brightly colored insects are generally beneficial because they eat aphids and other pests.
Background & Behavior
However, certain species, like the Asian lady beetle, can invade homes in large numbers during winter. Indoors, they can stain walls and emit unpleasant odors. Sealing entry points helps keep them outside where they belong.
