Indoor Ficus with yellow spots

Question

I have had this ficus for about 20 years. All of a sudden all of the leaves now have these yellow and brown spots. Any ideas what this is and how to fix this?

Answer 1

This type of leaf damage can be caused by a few different insects.
I would treat the plant with Neem Oil, this will treat the insects and is safe for people and pets.
Here is some links for you.
