In October, there were thousands of tiny white bugs climbing all over my plum tree. I sprayed them with a general purpose bug killer and it killed most of them. However, the tree started to get shiny on the limbs (almost like someone sprayed lacquer on them). This has continued and I don't know if this is a problem or a natural occurring thing. This is also my first plum tree so I don't know what to do. Will this kill my tree or cause the fruit to be no good? Please advise.

Most insecticides will either have oils, or soaps, and they will cause this. This is no cause for concern, though. This will come off with time.
