Hello,

That is a Brown marmorated stink bugs, Halyomorpha halys (Hempitera: Pentatomidae).

The brown marmorated stink bug is an invasive insect native to Japan and Asia. It was first discovered in Michigan in 2011. Since then they have been slowly spreading throughout the state. In addition to causing damage to plants and fruit, brown marmorated stink bugs are a major nuisance because adult stink bugs often seek shelter inside houses and other buildings in the fall of the year. Once inside, they congregate almost anywhere. These pests will not cause structural damage or reproduce in homes. They do not bite people or pets. Although they are not known to transmit disease or cause physical harm, the insect produces a pungent, malodorous chemical and when handling the bug the odor is transferred readily.

Insecticide spray can be applied to protect garden plants, fruit trees and ornamentals from this pests. For homeowners, the best products are cyfluthrin (sold as BioAdvanced Vegetable and Garden Spray), bifenthrin (sold as Ortho Bug B Gon). Be sure to read and follow all instructions on the label before using any pesticide.

Howard
