Ive read in several places of people putting certain insects inside the snake tanks for self-maintained cleanliness.

Saw someone recently mention having small "isopods and springtails" in the garter tank, can't remember where it was posted or who posted it.

Anyhoo, anybody know anything about this? Are there insects you can put in the cage that pose no potential threats to the snake, and would clean up after the snakes?

Mostly just curious but it would be pretty neat if it works
