Hi Joan,

Are you certain that the insects around your Allium are hoverflies?

I cannot even walk past the tree for the flies that have been there nonstop for two days. It’s like being in a garbage dump and inconvenient because it is the main pathway to the front door. I am considering how fortunate I am that they are covering the tree and not in my home. Are these useful flies, hoverflies, that will leave after a short period of time or is it time to start spraying, trapping. I have a jar of vinegar and sugar with a paper funnel and has now set a adhesive flytrap barrel next to the tree. The bees and wasps are staying on top of the allium and are not a problem.
Rosebushes, clematis,, sweet alysumm and garlic are also planted in the same area.
