Hello We have had scales on our magnolia tree for the last few years. We have been treating the tree with Neem Oil which doesn’t seem to be helping. It is dripping much sap and attracting many bees. We are very concerned and don’t want to loose our tree. Many branches on the inside of tree have scales on them. Can you recommend a spray that might kill these scales or a tree spraying company that specializes in killing them. I have attached 2 photos. One showing the leaves on the inside of tree that have black spots on them and the other with scales on the inside branches. Thank you for your advice Kathy severson
