Q.How Can I Treat Scale Bugs In My Pachira?
I have been seen decay of the leaves with what looked like fungus but finally saw the little black spot that came out after scraping so now all makes sense. I would like to effectively get rid of this as I have other plants at home. Thanks!

Sure! After scraping as many off as you can, you will need to treat with the insecticide of your choice. The important thing is to treat until there is no return of the pest. Just be sure to follow the instructions of the pesticide that you choose.
These can be quite resilient, and they WILL return at some point. Keep your treatment handy so that you can be ready when they do.
