I picked all the scale bugs off of my Hokkaido, and kept an eye on it for several weeks, picking/squashing each one. It took some time, but it was worth it. I didn't use any treatment other than that, and it has been pest free for weeks now.

So at least pick them off, whether or not you use a systemic as well. It seems like I have heard that elms don't care for systemics, do some searching to find out if this is the case before using anything.
