HELP Tiny sand colored bugs

[G-man]

Just took a look in our tortoise enclosure and saw tiny little bugs. They are smaller then a grain of sand and the same color. We have never seen them before and we concerned. If we move the soil around and look really close then we can see them. The only reason we saw them is the tortoise got a hold of a worm and left half of it by a plant. When we went to take the piece out we saw them on it. Any help will be appreciated

Not familiar with these, someone else I'm sure knows what they are, couple questions that may help other people:
Indoor or outdoor enclosure?
What kind of substrate? (can't remember if you said soil)

Anytime I start seeing bugs I do a complete substrate change,but that's for an indoor enclosure

They are likely collembolans (spring tails). These are harmless, feeding on organic mater and microorganisms in the soil.
