Learn How to Get Rid of Asian Lady Beetles in Wisconsin
As the crisp fall air settles in and the days grow shorter, you may notice an increase in the number of ladybugs in your home. But before you start thinking you’re lucky to have these cute, garden-friendly insects indoors, you might want to take a closer look. What you’re likely seeing are Asian lady beetles—an invasive species that can be both a nuisance and a threat to your home. Advanced Wildlife Control., serving Ozaukee County, Milwaukee County, Washington County, and Waukesha County, will help you identify Asian Lady Beetles, why they invade homes, the problems they pose, and most importantly, how to get rid of them.
Identifying Asian Lady Beetles
Asian lady beetles might look like their beneficial cousins, the ladybugs, but they can be a nuisance when they invade your home. They are often mistaken for the familiar ladybugs due to their similar shape and color. At first glance, Asian Lady Beetles and ladybugs seem almost identical. However, there are key differences that can help you distinguish between the two:
- Size – Asian Lady Beetles are slightly larger than ladybugs. They can range from 5 to 8 millimeters in length.
- Color Variations – While ladybugs are typically a bright red with black spots, Asian Lady Beetles can range from red to orange, and even yellow.
- Spots – Ladybugs usually have numerous black spots, whereas Asian Lady Beetles may have a few spots or none at all.
- Markings – One of the most distinctive features of Asian Lady Beetles is the “M” shaped marking on their head, which ladybugs lack.
How Do Ladybugs and Asian Lady Beetles Differ?
While ladybugs are beneficial insects that help control garden pests like aphids, Asian Lady Beetles can be problematic when they invade homes. Here’s how they differ:
- Odor – When threatened, Asian Lady Beetles release a foul-smelling yellow liquid that can stain surfaces and cause allergic reactions in some people.
- Bites – Although rare, Asian Lady Beetles can bite humans, whereas ladybugs do not. These bites may cause minor irritation and discomfort.
- Habitat – Ladybugs tend to congregate in large clusters in sheltered areas during the winter months, whereas Asian lady beetles are known to invade homes more aggressively as they seek cozy overwintering spots, often leading to infestations inside structures.
Why Do Asian Lady Beetles Invade Homes?
These beetles are overwintering pests, meaning they seek shelter in warm, protected places to hibernate through the cold months. They are particularly attracted to homes with sunny, southwestern exposures. As the temperatures drop, they start aggregating around doors, windows, and even under siding, looking for ways to get inside.
Problems They Pose
While Asian Lady Beetles may seem harmless, they can actually cause several problems for homeowners:
- Infestation – These beetles can quickly multiply and infest homes in large numbers. Not only is this unsightly, but it can also be a major nuisance.
- Allergic Reactions and Bites – Although Asian Lady Beetle bites are rare and generally harmless, they can cause discomfort. More concerning is the potential for allergic reactions. The yellow liquid they secrete can trigger allergic responses in sensitive individuals, leading to symptoms such as eye irritation, asthma, and skin rashes.
- Damage to Property – The yellow liquid excreted by Asian Lady Beetles is not only foul-smelling but can also stain walls, furniture, and fabrics. This can lead to costly cleaning and repairs. Additionally, large numbers of Asian Lady Beetles can leave behind unpleasant odors and attract other pests like spiders.
- Impact on Pets – If you’re wondering, “Are Asian Lady Beetles harmful to dogs?” the answer is yes, they can be. Pets love to bite at these colorful pests. However, if they bite or ingest them, they may experience mouth irritation or gastrointestinal upset.

Preventative Measures
