Asian Lady Beetle

Another winter home invader is the Asian Lady Beetle, Harmonia axyridis. This beetle has spread across North America during the last 20 years.  In an attempt to control Soy Bean aphids, this beetle was introduced from Japan, Korea, and other parts of Asia.  Introductions began as early as 1916, and many were unsuccessful.  Now the beetle is often abundant.

Most households do not welcome these beetles. Once inside, they are everywhere.  They smell bad and they bite.  They out compete and prey upon native lady bugs.  They also damage fruit crops.  They spoil the taste of some wines made from infested grapes.  A few people are allergic to these beetles.

On the other hand, Georgia peach growers now rely less heavily on pesticides after the farmers used lady beetles to control aphids.  You may not want to try to control a home invasion of Asian Lady Beetles with pesticides.  Asian Lady Beetles are preyed upon by Carpet Beetles.  If you wipe out the lady beetles, the Carpet Beetles, which also live in homes, move on to consuming your carpets and other linens. As in the case of Box Elder Bugs, vacuuming the invertebrates may be your wisest remedy.  Much of this information is from Wikipedia and the University of Washington.
