Many people search for “ladybugs” this time of year, but most of the insects gathering on siding and slipping into homes are Asian lady beetles. They look similar, but their behavior is very different. These beetles invade in large numbers, release a strong odor when disturbed, and hide inside walls until warmer weather returns.

You protect your home best when you understand what attracts them and how recurring pest control keeps them from settling indoors.

How to Tell the Difference Between Asian Lady Beetles and Ladybugs

Many homeowners mistake Asian lady beetles for ladybugs, but a few key details help you spot the difference quickly.

Asian Lady Beetles

• They have a small black “M” or “W” shape on the white area behind the head
• Colors range from light orange to deep red
• They gather in large numbers
• They bite when handled
• They enter homes to overwinter
• They release a strong odor and yellow staining liquid when stressed

Ladybugs

• They have a bright red shell with a clean black head
• Spots are more uniform and predictable
• They cluster outdoors but rarely enter homes
• They do not bite
• They do not produce strong odors or staining fluids

If you see swarms on sunny exterior walls or find beetles slipping inside around windows and siding gaps, you are almost always dealing with Asian lady beetles.

Why You See Asian Lady Beetles Instead of Ladybugs

Asian lady beetles gather on sunny sides of homes when temperatures shift. They search for warmth and a place to overwinter. That is why you see them:

• Swarming on light-colored siding
• Gathering around windows
• Slipping through cracks and gaps
• Showing up inside during warm afternoons

True ladybugs stay outdoors. Asian lady beetles enter structures aggressively.

Why They Invade Homes During Fall

Fall weather triggers beetles to search for shelter. As temperatures cool, they move toward:

• Attics
• Wall voids
• Window frames
• Unsealed door trim

Once inside, they gather in hidden areas and stay through winter. Homeowners often see them reappear during brief warm spells.

Problems Asian Lady Beetles Create Indoors

These beetles do more than become a nuisance.

• They release a strong odor when stressed
• They stain surfaces with yellow secretions
• They bite when handled
• They trigger allergies for some people
• Large groups hide in walls until spring

A small gap can allow thousands to enter over a few weeks.

How Homeowners Can Reduce Activity

Seal Small Openings

Focus on windows, doors, siding seams, and attic entry points.

Repair Screens and Weather Stripping

Any tear or gap makes it easy for beetles to slip inside.

Reduce Outdoor Attractants

These beetles are drawn to light-colored walls and sunny sides of the home. Redirecting exterior lighting can help.

Use a Recurring Pest Control Plan

Seasonal treatments help block access before beetles gather in large numbers.
