I used the recommended homemade spray twice (3 days in between), and scraping, and haven't seen anymore. May come back later, not sure. Hope not.
Did bring it to my bonsai club, they said it was scale. They recommended just using Q-tip and alcohol and dab on each one.

CARL’S SOAP SOLUTION!
INGREDIENTS
Water
Dish Detergent
Rubbing Alcohol
Vegetable Oil
DIRECTIONS
Fill a gallon jug with water and add one (1) or two (2) tablespoons of dishwashing detergent and one (1) tablespoon of vegetable oil (or Neem oil). Shake up the gallon jug to mix the ingredients.
Fill this solution from the gallon bottle into a spray bottle and just before using add 1 to 2 two caps full (from the rubbing alcohol bottle) of rubbing alcohol and spray immediately. If you do not use the full bottle of spray, the next time you are going to use the soap/alcohol solution add the same amount of rubbing alcohol again, since the alcohol will evaporate. You can store this soap/oil solution in the gallon jug for months on end. It does not seem to go bad.
Spray on plants covering all leaf and stem surfaces. You may have to spray from three to four times with intervals of three days. This works for almost any kind of pest that attacks your trees, including scale.
I do not wash off the spray and have seen no adverse reaction to the trees from this mixture.
