Any easy and effective way to rid green scales and white flies?
gnappi:
Maybe I'll give malathion oil a try
fruitnut1944:
I used imidacloprid once in my greenhouse for scale on citrus and other fruits. It was a one time only application of granular to the soil. That one application killed bumblebees brought in for pollination for the next three years. I'll never use it again.
If you think it's safe for bees after flowering or when bees aren't present think again.

Wow.... WOW... Sounds like a GREAT PRODUCT for my application as I can only find granules to be reapplied every 3 months...
Could you give us all the specific name of the product brand purchased that was effective for 3 years as I would love to buy a lot of it. Thanks...

You may want to re-read his post. He did not say how effective it was on the pests, only the bees :-)
I have few enough bees around here, I don't want to be killing them off.

I would say using your hands (with gloves on) and scrub the scales off. Depending on the size of your tree it would be easy enough but if you have a large tree I wouldn’t recommend it. Also, go after the ants. I’ve found that eliminating or reducing ants in the yard helps to keep other pests’ numbers down as well. But ant bait is $$$.
Goodluck!
