Re: Sambucus nigra ant attack

Hi, Jenneffer,
I am thinking your Sambucus has blackfly - also known as black aphids. They are very tiny which is why you thought they were eggs. Aphids will suck the sap from the plant and typically attack young, tender shoots and flowers, etc.The ants are attracted to the honeydew the aphids secrete. The washing up liquid will work for a little while but you will need to repeat this frequently. You can purchase an organic insecticidal soap from garden centres which will be stronger, but will need more than one application as well. Strongest defense is a chemical pesticide.
