Tree ID / arborist?

[DSB OUTDOORS]

Looks like scale. Good luck, those things are nasty. Depending on the tree and the specific bug, I think you can spray a special oil on them when the babies hatch (little bugs hiding under the shells), and then do it again 2 weeks later and again in the winter (or something like that). I'm not a tree guy, but I've definitely seen those before.

One other thing... that "sap" you mentioned might also be scale poop. They call it "honeydew" and it can also cause mold, or at least encourage it. If I remember right, a lot of the black mold some of our trees had on them was supposedly caused by scale honeydew.

^^^^^ Brian hit it. It indeed tree scale. And that sappy shit is shit called Honeydew. I'd call O-Tool's garden center and ask them if they have a residential spray they might sell. But it is hard to get rid of. I know I don't have any at my shop right now.

Thanks DSB. That explains the black mold on my awning.

You bet, I believe it's best to apply the dormant oil in winter just before the scale hatches. I'll see if I can find out when that might be for ya.

Thank you. On the chance that I do nothing, what are the risks? I assume the life of the tree in is in peril, but what about other trees in the neighborhood? Also, will getting rid of the scale help the sapping issue (since it's aparently not sap)?

Scale Insects
Male scale insect are harmless to trees, but the female scale insect can kill a full grown tree by sucking the sap out of it. Female scale insects are wingless, about ½ inch or less in size and have differing body types according to scale type.
What all the female scale insects have in common is their long, needle-like feeding tube they insert into the tree. The female scale insect will crawl around on a tree until it finds a lodging place, then it will insert it's needle-like feeding tube into the tree and remain in that location for life.
Most trees can be sprayed with dormant oil to smother the scales and their eggs, but some trees, like a Japanese maple of Sugar maple can not tolerate dormant oil spray. For those trees, spray an insecticide on the tree at two week intervals during the late spring and early summer to kill the newly hatching scale insects. Check with the local County Extension Office or nursery to find out which control method is best for the particular tree.

My brother had recommended a systemic pesticide made by Bayer that I can pour into the ground, since it is too late to spray. Also considering getting an injection. Thanks for the new knowledge everyone. Brother thinks I also may have aphids, which explains the sapping and wasps. I know I had aphids on my grape vine before I cut it down.

Looks like European elm scale. That is if it is and elm tree you have. Looks like it from the branch. The bayer product will not work all that well. Tried the same ingredient for a while with minimal results. It usually takes multiple treatments with multiple types of products at different times of year. If it is a large tree it will be tough to get it under control yourself. I sent you a pm with my number.

Thanks Vince, got the pm. The direction I'm headed sounds like an injection. I'll get some identifying pictures of the tree tonight. My brother seems b to think it is an Ash.

Here are the leaves


And the bark


You can see how the top side of the bark is black from the infestation.
