Apart from those I don't know. There are other roaches you could breed, but they're more likely to escape than Dubias or Red Runners lol...
I might save a bit for the Dubias or get red runners. Depending on the climate Dubias won't be able reproduce and infest bery effectively. I haven't had one escapee yet.
Earthworms are iffy. I don't know how to breed nightcrawlers. I've been thinking about breeding hornworms, but from what I've read it's not an easy breeding project. I'll add any more ideas after some looking later.
