The Asian beetle, also known as the Asian lady beetle or Harmonia axyridis, has become a common household pest in many parts of the world. Originally introduced as a form of biological pest control, these beetles have multiplied rapidly and become a nuisance for homeowners. In this blog post, we will discuss how to identify an Asian beetle infestation and provide helpful tips on how to prevent them from invading your home.

1. Identification:

The first step in dealing with an Asian beetle infestation is being able to identify them correctly. Asian beetles resemble ladybugs with their oval-shaped bodies and colorful appearance. However, they can vary in color, ranging from yellow to orange and even red. One distinguishing feature of Asian beetles is the M-shaped mark on their thorax.

2. Behavior and Habits:

Understanding the behavior and habits of Asian beetles can help you identify and prevent an infestation. These beetles are attracted to light, especially on warm and sunny days. They often congregate on the sunny side of buildings or around windows and doors. Asian beetles are also notorious for their unpleasant odor and can release a yellowish fluid when threatened or squashed.

3. Prevention:

Preventing an Asian beetle infestation is much easier than dealing with one. Here are some effective prevention methods to keep these pests at bay:

– Seal any cracks or gaps: Asian beetles can enter your home through even the tiniest openings. Inspect your doors, windows, and foundation for any gaps or cracks and seal them with caulk or weatherstripping. This will prevent the beetles from finding their way inside.

– Install screens: Installing screens on windows, doors, and vents can act as a physical barrier, keeping the beetles out while still allowing fresh air to circulate.

– Use light traps: Since Asian beetles are attracted to light, using light traps can help reduce their numbers. Place sticky traps or adhesive tape near windows and doors to catch any beetles that try to enter.

– Apply insecticides: Insecticides can be an effective tool in preventing Asian beetle infestations. However, it is important to use insecticides specifically formulated for Asian beetles and follow the instructions carefully. Consult a professional pest control service for the best treatment options.

4. Natural Remedies:

If you prefer more natural methods, there are several remedies that can help deter Asian beetles:

– Citrus peels: Asian beetles are repelled by the smell of citrus. Place citrus peels around windows and doors or spray citrus-scented essential oils to deter them.

– Use vinegar: Mix equal parts of vinegar and water and spray the solution around entry points to repel Asian beetles. This natural repellent can also be applied to windows and screens.

5. Garden Care:

Maintaining a well-maintained garden can also help prevent Asian beetles from infesting your home. These beetles are attracted to aphids and other soft-bodied insects, which they feed on. By keeping your garden free of aphids and other pests, you reduce the beetle’s food source and make your property less appealing to them.


Identifying and preventing an Asian beetle infestation is crucial for the peace and comfort of your home. By familiarizing yourself with their appearance and habits, implementing preventive measures, and utilizing natural remedies or professional treatments if necessary, you can keep these pests from invading your space. Don’t let Asian beetles ruin your indoor and outdoor enjoyment – stay proactive and protect your home from these pesky invaders.
