Asian lady beetles clustered on a window frame

Asian Lady Beetles in Jordan & the South Metro?

Look-alike ladybugs that gather by the hundreds on fall days to find indoor shelter. Here is how we handle it.

How do you get rid of Asian lady beetles in Minnesota? Our 2-treatment fall program is a 1-2 punch: the first treatment flushes them out and eliminates the current population, and a follow-up 7 to 21 days later solidifies the hold to take you into the colder months as swarms land and try to get in. We treat the foundation, siding, and around windows, doors, and soffit vents before they cluster. If they have already gotten in, a spring baseboard treatment helps.

Common questions

When should I treat for Asian lady beetles?

Fall is the time. A September or October exterior treatment before they cluster is most effective. If they are already inside by spring, an interior baseboard treatment helps.

How does the 2-treatment fall program work?

It is a 1-2 punch. The first treatment flushes Asian lady beetles out and eliminates the current population on your home. A follow-up visit 7 to 21 days later solidifies the first treatment and gives it the hold to take you into the colder months, killing off swarms as they land on your home and try to make their way in.

Do I need a yearly plan?

If your home gets them every year, a maintenance plan makes sense. We can time a fall treatment each year so they never get established inside.

Are they harmful?

They do not bite or cause structural damage, but they stain surfaces and some people are sensitive to the odor they release when disturbed
