Would a stink bug eat a bedbug?

Ladybugs eat small plant eating arthropods. Almost exclusively, their main diet consists of aphids. The bugs that do eat bedbugs are not the kind you want in your home (cockroaches and house centipedes) and you would need a large number of these pests to make any impact on a population of bedbugs.

If you have bedbugs, it is strongly recommended that you call a professional exterminator who would come into your home and kill the bed bugs with heat, cold or a chemical insecticide.

The short answer? No, ladybugs do not eat bedbugs.
