Visible activity
Watch for orange or red beetle clusters. This clue is most useful when considered with location, timing, and other evidence.
Insect Control
Asian Beetles
Control.
Asian beetle exclusion and seasonal control for exterior swarms and indoor overwintering.
Quick answer
What should you know about asian beetles?
Asian lady beetles gather on sunny buildings in fall and enter cracks to overwinter. They may appear indoors in large numbers during warm winter or spring weather. Bowers begins with identification and inspection, then matches control, removal, or exclusion to the species, structure, season, and conditions found.
Understanding the problem
A careful look comes first.
Asian lady beetles gather on sunny buildings in fall and enter cracks to overwinter. They may appear indoors in large numbers during warm winter or spring weather.
Contrasting, sun-warmed surfaces and openings around trim, siding, vents, windows, and rooflines attract overwintering beetles.

What to watch for
Common signs of
asian beetles.
One sign may not confirm the problem. An inspection combines evidence, location, timing, and property conditions.
Tracks or evidence
Watch for bugs around windows and lights. This clue is most useful when considered with location, timing, and other evidence.
Structural clues
Watch for yellow staining when disturbed. This clue is most useful when considered with location, timing, and other evidence.
Repeated patterns
Watch for indoor activity in upper rooms. This clue is most useful when considered with location, timing, and other evidence.
The Bowers approach
From evidence
to a clear plan.
The exact method depends on the species, activity, structure, season, and conditions found during inspection.
- 01
Identify
Confirm the insect and distinguish asian beetles from similar species before choosing treatment zones.
- 02
Target
We confirm Asian beetles, evaluate gathering surfaces and structural gaps, address seasonal activity, and recommend exclusion timing.
- 03
Prevent
Address entry points, moisture, food, nesting conditions, and seasonal pressure that can support renewed activity.
Prevention priorities
Make the property
less inviting.
Prevention recommendations should reflect the actual access points and conditions at your property.
Limit access
Seal exterior gaps before fall. Apply this step only after confirming it will not trap animals or interfere with needed ventilation.
Reduce attractants
Repair window and vent screens. Apply this step only after confirming it will not trap animals or interfere with needed ventilation.
Maintain the property
Maintain soffits and trim. Apply this step only after confirming it will not trap animals or interfere with needed ventilation.
Respond early
Vacuum indoor beetles instead of crushing. Apply this step only after confirming it will not trap animals or interfere with needed ventilation.

FAQs.
Common questions about identification, control, removal, and prevention.
What are common signs of asian beetles?
Common evidence includes orange or red beetle clusters, bugs around windows and lights, yellow staining when disturbed, indoor activity in upper rooms. An inspection helps connect those signs to the actual source.
Why are asian beetles around my property?
Contrasting, sun-warmed surfaces and openings around trim, siding, vents, windows, and rooflines attract overwintering beetles.
How does Bowers handle asian beetles?
We confirm Asian beetles, evaluate gathering surfaces and structural gaps, address seasonal activity, and recommend exclusion timing.
Can I prevent asian beetles from returning?
Prevention may include seal exterior gaps before fall, repair window and vent screens, maintain soffits and trim, vacuum indoor beetles instead of crushing. The best priorities depend on the property and active source.
When should I call about asian beetles?
Call when activity is repeated, inside occupied areas, causing damage, creating a sting or exposure concern, or involving an opening you should not seal without confirming it is clear.
