Do I have lice in my boxwood?

Garden Experts
Today I found some kind of lice in a number of box domes! What can I do about it?

The answer

If they are indeed aphids, you can combat them using environmentally friendly means. However, you should first check whether the insects are actually aphids, as they could also be mites. If they are aphids, then under a magnifying glass you will be able to see a pair of siphons standing upright on the rear of the insects' bodies — they look like antennae on the back.
