    You can prune off some branches. It will recover. Just be careful about taking really thick branches. Here is an article that will help: https://www.gardeningknowhow.com/ornamental/trees/elm/camperdown-elm-tree-information.htm

    Elms often are bothered with elm leaf beetles. These go through several life stages but they don't look like brown worms, to me. Look at pictures online to see for yourself. My only other suggestion comes from your comment that the elm is close to the house. Too close? Some elms grow to 80ft and have roots capable of cracking foundations, leaving just enough room for worms to enter.

    Can you include a photo? It sounds like you are doing what you should be doing, but if the wound is small enough, there might be a few things you can do to help it recover. If it is too major, it will just have to stand the test of time. Sometimes they can recover, and sometimes they cannot. A picture will help me to determine the best course of action.

    Can you include a photo? These could, very well, be termites! They look similar, so it can be easy to confuse them. In the meantime, collection of articles will give you more information: https://www.gardeningknowhow.com/special/organic

    Hm... This is unfortunate. This can happen with severe fungal infections due to an overly wet year, but this seems to have progressed rather quickly. Is there any living growth on it at all? If not then you can break the tip off of a branch. If it is still flexible and green, then you can cut anything off that is not. If there is no living growth and the entire things is brittle then you can try cutting it back completely. Sometimes this can help, but not always.

    I would also treat the area with wettable sulfur and dolomitic lime. This will treat most diseases in the soil and help to recondition the pH back to a more suitable condition.

    It's hard to see from the photo if it is powdery mildew (a fungal disease), or maybe giant white fly (an insect pest that puts out a cottony mass for self protection). If it's white fly you will see some white, winged fying insects in and about the white material.
    If its' a large elm tree you will need to hire a tree service or pest control service with spray equipment. If it's small you can use 70% need oil sprayed every week until the problem clears up.

    A tree or pest control service may use a more specific fungicide or insecticide for spraying or injecting, depending on their diagnosis.
