Pea/bean weevil.

Had it a few years ago & sprayed with a run of the mill insecticide. Peas shot up after that. Have to admit I don't know if they would have outgrown it anyway!

Others may advise re organic methods.

You bet.
No serious damage to be sustained commonly, if infestation is heavy , sow in well rotted manure.

what's the well-rotted manure do? And would it help putting some around existing pea plants?
