compost worms

[Wessie]

I found these compost worms the other morning, took this photo then put them straight back into the bin, but why did they do this, is it something i am doing wrong or is it just the weather, it hasn't happened since.
Thanks

Probably need more food or it's too hot or too wet - what's the bin like inside? Are you keeping it topped up? When was the last time you emptied it?

Turn the compost and keep adding kitchen scraps and shredded paper.
