Little bugs in my dubia keeper?

[Girlypop]

I bought some dubias from my regular supplier, dubia.com, about three weeks ago. Opened up the critter keeper just now and it’s full of these long black bugs. I have no idea what they are. The critter keeper stays closed in a drawer when I’m not feeding. I’ve never seen these guys before.

Is it still safe to feed the dubias to my beardie or should I throw them out?

They are safe, it's the clean up crew from where they are bred

Thanks!
