I thought I had got rid of mine, but now they are here again. snip

You might like to donate a few to scientific study. There was an article
recently in my local Eastern Daily Press paper about how researchers at the
John Innes Centre at Norwich had put out an appeal for gardeners to send
them live beetles and especially grubs. I'd been destroying quite a few in
the weeks before it was published but typically haven't seen any since.
Perhaps mine are sneakily lulling me into a false sense of security!
