What are these little black bugs in my Chives, Welsh and Spring onions? They don't seem to be eating anything, they are clustered around the base and a short way up some of the stems.
I really can't tell much from the picture. However insects are quite purposeful. If they are on your plants they are not there for a vacation. The most likely candidate are aphids who come in many colours.
Try a spray of soap and water at 5 ml/litre. Spray and leave on for a few minutes then rinse with water.
If they don't come back, job done!
They're onion aphids. They infest my green onions, and garlic. Although visible on the green garlic shoots, they get into the bulb. I've even found them inside garlic imported from overseas.
Just keep washing them off with water. But I find that they keep coming back if the plants are in anyway weakened by non-perfect growing conditions.
