Demestrid beetle larvae?

[timber64]

I discovered all of these under a feeding dish in my dubia roach bin. After a quick internet search, I believe them to be dermestid beetle larvae but would love confirmation from others. I do know there are some dermestids beetles in my bin, especially after the new fresh supply of roaches I just added. If these are baby dermestids, should I be concerned that my dubia roach bin could become overrun with beetles?

Those look to be buffalo beetle larvae, which are completely harmless! They're a great clean-up crew, too!

Dermatitus are hairy.
