I am watching some metallic colored beetles nearly destroy my Blue Lake beans. This is my first garden and I've been adamant with my husband that it remain organic. Everything I've read says that hand picking is the only option. Is there anything else that might help? There are probably 100s of beetles. I go out at least once a day and pick and dump them in soapy water. I work in the mornings and have a 7 month old baby so I'm only able to go out after he goes to bed. But I'm just wondering if my efforts are in vain. Can the beans survive? Is this just temporary? Thanks!
