No, freezing does not kill stink bugs.

Specifically, the insect in question (Pentatomidaefamily) can endure temperatures below -4ºF (-20ºC) according to science laboratory experiments. Stink bugs draw upon polyol cryoprotectants to defend themselves against damaging freezes and to keep body fluids from crystallizing. The substance in question is found in a stink bug's blood (known as hemolymph). The stink bug therefore will "thaw out" once temperatures rise.
