Brown Marmorated Stink Bug Update

In regions where brown marmorated stink bug (BMSB) has been established for several years in Kentucky (Louisville, Lexington, and eastern KY counties), this insect has become common in some locations.  It is now an economic pest on a number of fruit and vegetable crops within some of these same regions.  In urban areas, it can be very common on landscape trees, such as crabapple, redbud, tree of heaven, princess tree, and others bearing fruit, seeds or pods. BMSB will begin its migration to overwintering sites in the next few weeks.

Management

In situations where BMSB were a home or business invasion problem last year, it would be advisable to survey landscape trees around buildings in the coming weeks for stink bugs.  Direct inspection or simply tapping limbs over a white sheet may reveal the presence of BMSB. When dislodged, BMSB adults will drop 2 or 3 feet before flying away. If BMSB are common on these trees, owners may want to contact a profession to reduce stink bug numbers. Once they are indoors, stink bugs are best removed with a vacuum.
