Brown Marmorated Stink Bug
The brown marmorated stink bug (Halyomorpha halys) is a fairly new pest in North America. Adult bugs are 14-17 mm and dark mottled brown. The last 2 antennal segments have alternating light and dark bands. The exposed edges of the abdomen also have light and dark banding. Eggs are light green, barrel-shaped, and laid from June to August. The young bugs (nymphs) are yellowish and mottled with black and red. Older nymphs more closely resemble the adults. The host list is long and includes many shade trees and woody ornamentals such as Paulownia tomentosa (empress tree), Buddleia spp.(butterfly bush), Catalpa spp., Rosa rugosa, Lonicera spp. (honeysuckle), and Acer platanoides (Norway maple). Feeding damage appears as small necrotic spots on leaves and fruit. These stink bugs can also be a nuisance in homes and buildings as they seek shelter in the fall much like Asian lady bird beetles and boxelder bugs.
Management: Inside home vacuum up the bugs and dispose of the bag. There are no chemical recommendations available.
