I recently bought a myer lemon bush in TN. I've noticed holes in the leaves and yellow spotting. I then noticed jet black spots on the leaves limbs and even the plastic container its potted in. I took it in to the place I bought it from and they said they were unfamiliar with what it could be other then a type of egg. And knocked off most of them and pruned it. The next day I spotted about 5 little pest on the leaves. I've since showered the plant and started a regime with neem oil. I could just use some help on identifying what this is and whats the best treatment.
