How can you suppress the Terminated

How can you suppress the Terminated message that comes up after you kill a process in a bash
script? I tried set +bm, but that doesn't work. I know another solution involves calling exec 2> / dev/null, but is that reliable? How do I reset it back
so that I can continue to see stderr?
