Need+soap solution should do it. Dip cotton buds in that and manually remove them.

Thanks. Good to know I'm on the right track. How do I keep them away though?

I should also mention I see similar looking white bugs at the bottom of the pot (running around on the tray the pot sits on to collect excess water). Although since I started spraying the numbers there have reduced.

I’d spray with a 50/50 mixture of isopropyl alcohol and water.

Neem oil smells awful and takes a while to work. The alcohol will kill instantly and dries fast enough as to not damage the plant.

Thanks, am trying this. Wish i knew what the pests are! Some of the leaves are also losing their green from the edges. Although im not sure if this is from the bugs or getting too much water (from my plant spike while i went away on holiday).

Are they spider mites? We had a bunch on a kalanchoe and were able to remove them by swabbing them with the 50/50 isopropyl alcohol (~70-90%) and water. I'm surprised you can see them move; don't think we saw the little guys move on our plant.

I don't think they are spider mites - at least not any like ones i've seen before on my calathea! I always thought spider mites were either black or red?

In any case i stand looking at them for about 2 mins, blowing a little on the leaf and then see them move ever so slightly...
