I have a small edible shrub in my backyard. Lately, I noticed some bugs that I have never seen before, or on any other shrubs. Attached is a photo of the bugs. They are about 1/8" long (with a common ant in comparison) , black with white dots. I don't see much damage yet, but I assume they suck the sugary juice out of the trunk. Can anyone identify what they are, and how to get rid of them? Thanks.
