Asian Ladybugs

Asian ladybugs, also known as Harlequin ladybugs, are colorful beetles commonly found throughout Tennessee. They are larger and more aggressive than native ladybugs and are easily recognized by their bright orange or red bodies with black spots. While beneficial in gardens for controlling aphids and other pests, Asian ladybugs can become a major nuisance when they invade homes in large numbers, especially during the fall months.

Why they’re a problem

  • Nuisance indoors: Asian ladybugs seek warmth as the weather cools and often enter homes through cracks and openings. Once inside, they cluster in attics, wall voids, and around windows and doors, creating a bothersome presence.
  • Odor release: When disturbed or crushed, these beetles release a strong, unpleasant odor and may leave yellowish stains on walls, curtains, and furniture.
  • Allergic reactions: Some people may experience allergic reactions, including skin rashes, respiratory issues, or eye irritation, after contact with Asian ladybugs.
  • Rapid reproduction: Female Asian ladybugs lay hundreds of eggs near aphid populations. This high reproductive rate contributes to their large numbers during infestations.
  • Difficult to control: Due to their tendency to hide in hard-to-reach places and their ability to fly, Asian ladybugs are challenging to eliminate without professional help.

Signs you may have Asian ladybugs

  • Sightings: Asian ladybugs are about 7 to 10 millimeters long, with a distinctive bright orange or red color and varying numbers of black spots on their wing covers.
  • Indoor clusters: Large groups of these beetles indoors, especially around windows, attics, or wall cracks, are a common sign.
  • Odor and stains: Noticing a strong smell or yellow stains near clusters indicates their presence.
  • Increased activity in fall: Asian ladybugs tend to invade homes in large numbers during the cooler months seeking shelter.
  • Professional Asian ladybug control includes sealing entry points, safely removing beetle clusters, and treating both indoor and outdoor areas to reduce populations.
