Asian Lady Beetles: A Comprehensive Guide to Identification and Extermination

The Asian Lady Beetle (Harmonia axyridis), also known as the multicolored Asian lady beetle or Harlequin Ladybird, is a species native to Asia but has established populations in North America and Europe. This small beetle is best recognized by its dome-shaped body and varying color patterns.

Asian Lady Beetles


Asian Lady Beetles are small insects, usually ranging from 0.2 to 0.8 cm in size. They have a dome-shaped body and a pair of antennae. The beetle’s most distinctive characteristic is its color, ranging from red and orange to yellow and black, often with multiple spots. It’s essential to note that the number of spots can vary, with some beetles having no spots.

A significant feature that differentiates Asian Lady Beetles from other lady beetles is the “M” or “W” shaped marking they carry on their pronotum (the area behind the head). This marking can sometimes be challenging to spot due to its size, but it is a definitive identification trait.

Extermination Techniques

Asian Lady Beetles are beneficial insects, controlling aphid and scale insect populations. However, they can become a nuisance when they invade homes in large numbers. Here are some common beetle extermination techniques:

  1. Mechanical Control: A vacuum cleaner can be a non-toxic and effective way to remove beetles from your home. Remember to promptly dispose of the vacuum bag outside to prevent the beetles from returning to your home.
  2. Chemical Control: Several insecticides are approved for use against Asian Lady Beetles. However, these should be used cautiously as they can also affect non-target species. Always follow the label instructions when using insecticides.
  3. Professional Pest Control Services: If the infestation is severe, hiring a professional pest control service might be best. These experts have the tools and knowledge to handle the situation effectively and safely.
