My advice on the traps is to move them far away from the things you want them away from. Japanese beetles will come from miles away. The one time I used them, we one had a quarter of an acre. Every JB in Ohio came to my yard. Never again until I got more property, then stick them on the outskirts of your yard.
Yup!! We’re on the same page with the JB traps:

You are right about the traps, they will draw more beetles in.
On beans, which are good for the heart BTW, all we have grown for 5 or 6 years now are the Chinese long beans. We love them. Fast growing but very slow to thicken up and go to seed inside. Tender, flavorful, and less cutting off ends. We used to have them growing up a piece of fencing but the last 3 years we have sent them up a pole. Super easy to pick and they have a long season. Used to grow only bush green beans but they are a pain to pick. I have used the long bean seeds each year too.
