There are two lovely [info=elderberry]elderflower[/info] trees in the garden, but each summer they get covered in greyish, squidgy bugs. They are under every leaf, in clusters. Although they make my skin crawl, to see so many of them, the ants love 'em! If you wait and watch for long enough, you'll see one get carried off by an ant or two. Does anyone know what they are and how to get rid?
