Garden chafer

[fredg]

The Garden Chafer, Phyllopertha horticola, has appeared again in its masses.
They're now ruining the flowers on a white climbing rose.
Any ideas on how to combat them?
There's hundreds of the little £&$#&#@s

Can you post a picture of them please?

The climbing rose's flowers are now destroyed.
At least the rain has slowed them down a little.

Thanks Fred. (The first pic would have been enough. ) I had wondered if you were talking about what we call Maybugs (although they are active in OUR spring which is Aug-Nov) and are the brown shiny beetles which lay the eggs which turn into grass grubs. But obviously not. I don't think we have these. I've not seen them anyway though we have some native chafers in the mountains.

I have yet to see your garden chafer amongst the many critters good and bad that we get in the garden.  We do get a great many rose chafers which I am assured is garden friendly and I find its larvae in great numbers in the compost and leaf mould.  But to your problem: unless you are averse to chemicals you could try Provado Ultimate Bug Killer which I find is very effective against lily beetles.
