mystery insects in my Dubia Colony

[bonesandjones]

Haven't seen any posts like this, so forgive me if this is somewhere. I just decided to start breeding Dubias. After a few weeks of getting my shipment, I noticed a decent population of a mystery insect that I didn't notice before. They are small, but relatively fast for their small size. They look like some sort of centi/millipede...but idk if they safe for my Dubias, and safe for my cham. Any chance someone can ID these guys? Are they a nuisance, or an added treat to feed my Cham?

For reference, I live in So Cal, but I can't imagine they are native and snuck into the container. I'm guessing it was tiny eggs or nymphs etc. in my shipment that grew over the past few weeks.

I’ll guess that those are dermestid beetle larvae which are used as a clean up crew by many insect breeders. I get them with the crickets I buy and keep them in the tubs. They are harmless.

Ah, yes. Thanks. That would make sense that they came in the shipment.
