Asian Lady Beetle Bite What It Means and What to Do

You may have observed ladybug-like bugs gathering around your windows in the fall but did you know some of them can bite? These aren’t your friendly garden ladybugs. They’re Asian lady beetles, and while their bite isn’t dangerous, it’s adequate to raise fears for homeowners.

So what would you do if you’ve been bitten? More importantly, how do you remove these bugs out of your home for good? Let’s break down the facts and when it’s time to call an insect exterminator near you.

 

What Is an Asian Lady Beetle?

Asian lady beetles (Harmonia axyridis) look a lot like native ladybugs but have a few key differences:

• More orange than red, with varying black spot patterns
• Often have a white “M” marking behind their head
• Emit a foul, yellowish liquid when stressed
• Known to swarm homes in large numbers in the fall

Initially introduced to help control farming pests, they’ve later became invasive in many U.S. states including Wisconsin.

 

Do Asian Lady Beetles Really Bite?

Yes, Asian lady beetles can bite, but it’s not what you’d call a serious bite. They don’t have venom, and their bite doesn’t cut the skin deeply.

Why do they bite at all? Mostly out of interest or when attracted to the salt or moistness on your skin. Most people sense a slight prick or irritation at worst. In rare cases, bites or the beetle’s secretions may cause minor allergic reactions such as itching, redness, or eye irritation.

So while it’s not hazardous, it’s still unpleasant and preventable.

 

DIY Ways to Keep Asian Lady Beetles Out

If you’re trying to keep these pests out of your house, here are a few real steps to try:

• Seal entry points: Caulk cracks around windows, doors, and siding before fall.
• Use citrus or citronella sprays: These scents are natural repellents.
• Vacuum, don’t squash: Squashing them releases a strong odor and can stain surfaces.
• Turn off outdoor lights at night: Light attracts swarms, especially in fall.

These approaches work best when started before the weather cools, which is when they begin looking for shelter in the house.

 

When to Call an Insect Exterminator Near You

If you’ve already saw them swarming your siding or showing up inside your house, it’s time to get assistance from a professional insect exterminator near you.

A pest control expert can:

• Identify hidden entry points around your home
• Apply barrier treatments that remove and prevent infestation
• Treat interior wall voids or attics if bugs are nesting indoors
• Offer preventative services to stop yearly returns

Since Asian lady beetles are tenacious and recurrent, professional help guarantees you stay ahead of the infestation.
