Aphids on my Green Onions

Can you please identify these bugs, found in my green onions today in my greenhouse in Morgantown, West Virginia?  I didn’t know anything liked onions! Are they bad for my green onions or my greenhouse and how do I get rid of them?

Dear Bev,

These are Aphids.  Aphids, which are able to reproduce asexually, can quickly infest plants if conditions are good.  They end up on all sorts of plants from Christmas trees, to Cannabis, to Conifer Trees, to your green onions. They have piercing mouthparts that they use to suck fluids from plants.  You can try washing them off the onions with a hose, or if that does not work, spray them with water with a drop of insect killing soap included rather than to use pesticides. If you are really adventurous, you can try eating them instead of them eating your green onions!
