Can springtails occur naturally in vivarium substrate?

[BettaShawn]

I have a bunch of springtails in my vivarium soil. I first noticed when I saw maybe 7-8 of them feeding on my White's tree frog's waste (poop). Should I be concerned_considering I never added any and that they just appeared on their own, or should I consider it a blessing I guess to have an organic clean up crew?

Sorry for posting so many questions btw.

you have free labor working for you. springtails and white mites can be very beneficial for biodegration cleanup but I wouldnt leave any fecal matter sitting in the terarrium. if you want to get rid of the springtails or mites than put a piece of fruit in there(preferably melon rind) and wait until they swarm on it and toss away. most people would recommend leaving them in there, but for me I try to avoid infestations.
