Taking Care of The Bugs...  


Thrip 
Mix End-All solution with a drop of dawn dish soap in a 1 quart spray bottle and spray the plant/soil. Repeat the process every week until you see the new growth on the plant is no longer scared. Brewed cinnamon solution also kill thrips as well. Water the plant before applying End-All solution to the plant and soil. Leave plant in the shade or away from grow light for 12 hours, otherwise the plant will get burn if solution is apply on a sunny day. 


Aphid 
Spray with End-All solution or run the plant under a faucet with stronger water pressure.


Mealy Bug
Use a small paint brush or a toothpick to remove the mealy from the crown or under/between the leaves. Paintbrush can be dipped in rubbing alcohol and then swipe the mealy off the plant.


Root Mealy Bug
SOLUTION  1. Detach the plant from the root buy cutting it at the base, then root the plant in new soil and in a clean pot.
SOLUTION  2. Soak the pot in hot water at 49 degree temperature. This temperature won’t harm the root significantly, but will kill off the adult mealies. Repeat the process a few times  within a couple weeks to break the cycle as the eggs might still hatch within a few days. Or, soak the plant in water above the soil line for a few days to drown the mealy.


Scale
SOLUTION 1. Use a toothpick or paintbrush to remove the scales. Alcohol can be used by dipping the tool in the solution before apply onto the insect.
SOLUTION 2. Wash the plant in light soapy water (Not recommended for succulent with powder coated leaves) and scrape off any scales, then plant in new soil and a clean pot.


Tips
All the insects listed above do fly and look very similar to gnat, so to prevent the adult from infesting other plant by laying their egg, vacuum them up. Also, yellow sticking paper can be used to trap the flying adult.
