The brown marmorated stink bug is a 5/8 inch long x 3/8 inch wide shield-shaped insect; its upper surface is mottled with brown and gray, the underside is white with gray or black markings.
Stink bugs are not common fall invaders in Kentucky so please send insects matching the description above to your local Cooperative Extension Service office so that we may identify areas were populations may be becoming established. There is no quarantine program for this insect like ones seen with other exotic species. However, this insect has become a significant pest where it is established.
