Bugs in pool.

Is anyone else having problems with wood louse in their pools ?

When the pump jets go off in the morning, I’m taking dozens of them out...hundreds per week for the past month or so.

They are obviously dropping in overnight - never seen it before.

We've had them on the terrace rolled up into a ball. I thought they were seeds off the palm trees until one unrolled, I was just sweeping them up. None in the pool that I know off, christ knows where they come from, maybe conifers?
