Hi there,

It was time for my Ficus to be repotted today, and I noticed these worrying tiny black spots on the back of leaves and sometimes also on the front. I'm aware it's common to have those white droplets behind the leaf, but I cannot find anywhere someone who tells me what those little black dots are. I assume it's small bugs feeding on guttation.

Just in case, I gave it a shower with soapy water followed by a complete rinse in clean water, and I will do this for few days in a row, but I am unsure if it needs a harsher treatment. If you can help me, that would be great. Thanks!!
