I wonder if there are also flea beetles present and it is those which are causing the damage with the pollen beetles just being incidental, Dove?
It would be difficult to tell as the flea beetles would jump off at the slightest disturbance.
That makes sense Bob - it's a rare garden that has only one type of insect in it.
Lyn, there's nothing that I would spray on stuff that I was going to eat.
