As an occasional visitor to this site, I hope you will excuse me if this was
discussed before.

I have grown a few long beans (probably also known as snake beans). While
they are just fruiting, much of the beans are now covered with small dark
fly-like pests on the beans as well as the tender parts of the vines. As I
wish to consume the beans (if any are left), I am afraid to apply pesticides
which may be harmful for consumption. Appreciate some advice as to the
appropriate type of pesticide. Thank You.
