Skinny Bugs

I went over a friends house today and we noticed a few small bugs in one of his bins. These little bugs did not look like mites or ticks, they had an elongated shape and would move pretty rapidly. Anyone have an idea what they could be?

It's hard to tell without a pic, but my opinion is there is no such thing as "good" bugs in an enclosure...

Yes a picture would definitely help, even a hand drawn one. Even a very detailed description might be good enough. Also what area is your friend living in would also help. Like stated above no bugs in an encloseure is ideal, there are still degrees of bad when it comes to bugs, your animals health, and your health. There are products that will most likely wipe out anything that it may be, I would still want to know what it was to possibly prevent it from happening again.

Probably harmless springtails that come from the substrate.
