brown marmorated stink bug

5895  Thanks for helping identify this bug.  It was indoors, in the master bedroom (bed) at 2am.  Felt it crawling on my back.  It was a good size bug, able to cling to a q-tip, while I was trying to shake it off.  I just spoke with my wife, and she said her friend found a similar bug crawling on the cupboard.  That’s 2 in two days. Should we be concerned?  Don.

This is a brown marmorated stink bug, Halyomorpha halys (Hemiptera/Heteroptera: Pentatomidae). This is an introduced species that has become a serious pest in some areas of North America; they often invade buildings in search of shelter, but do no harm there.
