Throwing Tracy into her inner world could have adverse effects for Beelzebub. That's like the most vulnerable part of her soul, so even though it has a lot of nasty effects, Tracy could do more damage from inside. And she'd start turning the other victims in there into bees.

Beelzebub doesn't just have Dream Evil, also, she has soul-destruction and conceptual attacks, too. Overall, Beelzebub's flies would probably be more vulnerable to IO than she is, but she could probably handle it, at least for some duration of time.
