Q.How do I treat a flowering gum with Mottled Cup moth?
I have a young flowering gum tree with new growth that has been attacked by these stinging moths (Doratifera Vulnerans). Is there something I can treat the plant with?

My general goto organic pesticide is called neem oil. It will kill any bugs that chew on the plant but leave any that do not (like bees and ladybugs) alone. It is also systemic, so you only need to spray a small part of the tree to protect the whole tree. Here is more information:
