I have an infestation of these little mite like bugs all over the limbs of my mandarin tree. Tried eco oil spray yesterday but not sure if that will help. Can someone please confirm what bugs these are and a treatment?
Thanks

White rose scale?

It sure looks like some type of scale insects and a heavy infestation!

I keep looking at that and can't decide whether scale or whiteflies. Do they move? Whiteflies would fly if disturbed. Scale won't.

Most likely scale insects. Bayer's 3 in 1 spray. 3 applications a week to ten days apart.

The OP is in Australia and so any specific pesticide suggestions would need to be available there. So far I'm not finding it but Google always insists on giving me Canadian results for the most part, even though I included Australia in the search terms

You can get all kinds of pesticides for home use there in the USA that are not permitted/available in other countries.

Thanks for the replies. So far I've used an Eco Oil application on 2 occasions. I've just gone a weeks holiday so will reapply when I get back and also use a soft brush to see if I can remove the critters. They definitely don't fly. I've had 2 mandarins in pots in the same location for about 8 years and have never had a bug like this one. It seemed to appear over night. Apparently when temperatures get cooler, this is the time that they can multiply.
