I've had a worm farm for a year but no worm tea?

Does anyone know why?
It also smells like fish – though to be fair I think I put some fish in their tub.

What I don’t have though and what I’d like is worm tea?
I feel them fibre from juicing, oatmeal, noodles, tea and coffee, vacum dust, hair, left over food, normally veges – I was bad in feeding them fish.
But no worm pee.
I had worm pee initially but I was spraying it every now and then with a hose and the guy told me to stop doing that.
I’d like worm tea!!!
Why do I not have any?
The worms seem happy enough, none are dying, they are all red and plump looking and lots of new babies.
I do have a lot of those white little bugs crawling all over the food but not really worried about them.
Any ideas?
