Looking at your photos again, I'm also concerned that your shrub is surrounded by wood chippings. These insects will be quite happy in there too, so it would be a good plan to clear them from the contaminated area and chuck them on the bonfire as well.
Give the remaining stump (about an inch of stump, if that) a bucket of water, and wait for re growth.
