Pea and bean evil weevil

Hi,      We are being invaded by a pea and bean weevil.   I noticed they started on the broad beans - but they seem to cope.  However as I have planted early peas in the same bed this year, the evil weevil has started to notch the edges of the newly emerging pea leaves.   

Can anyone suggest a deterrant?

Thanks DD,
It might be okay for the broadbeans - they can cope, but the poor little pea shoots are getting bare of leaves.     I'll try spraying with insecticide.
