The multi-colored Asian lady beetle is a beneficial insect that has become established throughout the eastern United States. Originally introduced to help manage tree fruit pests, it has become a nuisance for homeowners and for some agricultural crops. In recent years, it has caused problems for growers of fall-ripening fruit, who find the beetles on and in their fruit during harvest. However, this insect also helps fruit growers during the summer months when adults and larvae provide biological control of many soft-bodied insects, including aphids and leafhoppers. During the fall when the adult lady beetles begin to search for energy and sheltered sites for overwintering, fruit crops can provide both of these resources and large numbers of beetles can infest fall-ripening fruit. Raspberry, blackberry, grape, and peach are particularly affected. As their name suggests, adult Asian lady beetles can take on many different color forms, varying from yellow to orange and red. Their spots may be dark on the wing covers or they may be faded or absent. Even the number and size of the spots varies. Many beetles have a straw-colored pronotum (top covering of middle body part) with markings that fuse into a regular- to irregularly-shaped "M" if viewed from the front, or "W" if viewed from behind.
The adult beetles are approximately a quarter-inch long, with a domed, round to oval shape. They are similar to many of the native species of lady beetles that do not cause homeowners or fruit growers problems. Native lady beetle species typically overwinter in sheltered sites outdoors and do not seek homes during the fall.
There are many remedies that work on Asian beetles for a short period of time. For long term control please call your professional.
