What is on my crape myrtle and how do I get rid of it?
It's either waxy scale or mealybugs. The mealybugs are actually related to the scale but not quite the same. Treatment for both is the same as already mentioned. However, make sure that you get a "summer" oil and not a dormant oil which is for use in the winter. The heavier oils can burn the foliage during the hotter months.
One way to identify for sure is to squeeze one in you fingers. If it's waxy scale, you will find a small pin-head sized bug that is bright pink/reddish colored inside of the white wax. Your finger will feel like you sqeezed a candle, hence the name "waxy" scale. Mealybugs are little guys that are whitish colored and have 8-10 legs (Can't remember off-hand). Just in case you were wondering.
If it's worth doing, it's worth doing right. If you wouldn't put your name on it, it ain't done right!
