Does anyone have any experience with natural predator solution to armored scale? I have a 25 foot tree infested with scale and have tried many things, but because of the sheer size of the tree i cannot get rid of them. Even if I manage to control my tree, all the neighbors have them. Looking for a more sustainable solution. I have read that ladybirds and lacewings eat them, but have not seen them in action even though they are present in other parts of my garden. only solitary wasps are seen having a blast. Any suggestions? 1000 ladybirds would be nice, 1000 wasps on the other hand...
