Answer: I don't know how long you've had your plant, but I wonder if what you're finding are little fertilizer pellets? Time-release fertilizer is often added to potting soil or dumped on top of the soil at the nursery. These little pellets are often green in color and can take many, many months to degrade before releasing their nutrients. Why not try squishing one between your fingers? A fertilizer pellet will be hard but will crack under pressure. Insect eggs will be quite soft. If the pellets are fertilizer, leave them there. If they're insect eggs, vacuum them up or brush them off the soil.
Best wishes with your ficus tree!
