Meet Bert Dinkins: All-American Pest Control Service Manager
When you’re faced with a pest problem, Bert Dinkins is a great guy to have by your side. Bert has been with All-American Pest Control for over nine years, helping homeowners prevent, identify, and solve pest problems of all kinds. Bert says,
At All-American, my role involves inspecting homes, identifying pest activity, and creating treatment and prevention plans that are tailored to each property. What I enjoy most about the job is being able to educate homeowners. A lot of the time, once people understand why pests are showing up and how they get inside, it makes it much easier to prevent future problems.
We asked Bert the most pressing questions homeowners have about Asian lady beetles. Read on to get answers to your questions, along with some peace of mind.
What Are You Seeing Right Now With Asian Lady Beetles?
Right now, we’re seeing a noticeable increase in calls about Asian lady beetles, especially during seasonal transition periods when temperatures fluctuate. Homeowners often report seeing them cluster on sun-facing exterior walls during the warmest part of the day, typically in the late afternoon when the sun is strongest.
Once they find entry points, they end up inside and gather around windows, light fixtures, and ceilings. In many cases, people don’t notice just one or two—they suddenly see dozens appearing at once, which is usually when they call a pest control company.
Compared to typical years, the activity can feel heavier when we have mild fall or early spring temperatures, because those conditions allow the beetles to remain active longer instead of staying dormant.
Why Are Asian Lady Beetles Surging This Season?
The biggest factors [in the lady beetle surge] are weather patterns and seasonal changes. As temperatures start cooling in the fall—or warming up after winter—these beetles look for protected places to overwinter.
Warm, sunny days followed by cool nights often trigger them to move toward buildings. Homes act like large heat collectors, so beetles naturally migrate toward them, looking for warmth and shelter.
Why Are They Suddenly Entering Homes?
Asian lady beetles are drawn to warm, light-colored surfaces and areas heated by the sun. Homes provide:
-
Warmth
-
Protection from cold weather
-
Small gaps that mimic natural overwintering spaces like rock crevices
Once they gather on exterior walls, they often find tiny openings and accidentally make their way indoors.
Gaps are often found:
-
Along rooflines
-
Around window frames
-
In siding
-
In attic vents
Are Asian Lady Beetles the Same as Ladybugs?
Asian lady beetles and ladybugs share many commonalities, but there are also distinct differences between the two species. These differences include:
-
Ladybugs tend to be bright red, while Asian lady beetles can range in color from red to orange to tan.
-
Asian lady beetles have a distinctive M-shaped mark behind their heads, but ladybugs do not.
-
Ladybug spots tend to be uniform, while Asian lady beetle spots have no particular pattern or number.
-
Asian lady beetles have oval-shaped bodies, and ladybugs have a more dome-shaped appearance.
-
Ladybugs prefer to stay outdoors, while Asian lady beetles often invade indoor spaces in large numbers.
-
Although they’re both considered harmless, Asian lady beetles can stain walls and fabrics and are considered more aggressive than ladybugs.
Are Asian Lady Beetles Dangerous to Your Home?
Asian lady beetles are not considered dangerous, but they can still cause several problems, including:
-
Large indoor infestations
-
Staining from the yellow defensive fluid they release
-
Occasional minor bites, which are harmless but surprising
For most homeowners, the biggest issue is simply the sheer number of them appearing inside the home.
Why Do They Appear All at Once?
Asian lady beetles use aggregation pheromones, which are chemical signals that attract other beetles to the same location.
Once a few beetles identify a good overwintering spot—like a wall or attic space—they release pheromones that signal other beetles to join them. That’s why infestations often appear all at once or in large clusters.
What Mistakes Are Homeowners Making Right Now?
A few common mistakes [that homeowners make when it comes to Asian lady beetles] include:
- Crushing them- This releases odor and staining fluids.
- Using indoor sprays- Sprays usually don’t solve the problem and can leave residue inside the home.
- Ignoring exterior prevention- The real solution is sealing entry points and treating exterior areas before they get inside.
What Should Homeowners Do If They’re Seeing Them Now?
What homeowners should do instead:
-
Use a vacuum to remove beetles [you find] indoors.
-
Seal cracks and gaps around windows, doors, and siding.
-
Consider professional exterior treatments before peak seasons.
Will This Surge Continue or Fade Out?
The surge usually lasts a few months during seasonal transitions, particularly in the fall when they’re searching for overwintering spots and in early spring when they become active again.
Homeowners can absolutely expect this to happen again in future years because it’s tied to natural seasonal behavior. The key is prevention before the season starts rather than reacting once they’re already inside.
