They are probably the oil seed rape beetle. I've never had them but have
heard about this on Gardeners' Question Time. I'm afraid I can't remember
the remedy. I think it was to grow something yellow and they'll go to that
instead of your sweet peas

Help!

I have grown some lovely, scented, sweet peas, but can't bring them
into the house because they are full of tiny black beetles - what
can I do please? I long to fill jugs and vases with them :-(
