Green stink bugs user their piercing mouth parts to suck plant juices. On vegetables and fruit this feeding results in unsightly blemishes. In soybeans, green stink bugs feed on the pods, deforming the beans inside.
Insecticides are available for controlling green stink bugs. Treatment should depend on the number of bugs found and their likely economic impact. Always read and follow all label instructions.
