If they're done and attracting more than their fair share of bugs it is indeed time to pull them (or cut them off and dig in the roots so as to leave more nitrogen available for the next crop).

But its not well-advised to plant more beans in the same spot. That would be giving the bugs and any diseases that might be lurking a head start.

Instead plant something unrelated to beans. Maybe some squash to replace what the borers and squash bugs are probably killing right now? Maybe an early-maturing melon? Maybe a cover crop to provide green manure before you put in the collards and other cool-season crops? Maybe use that bed for a temporary compost pile as you wait for cool-season planting time?

In fact I do have some yellow squash seedlings that are ready to go in. I have lost some nice squash plants to SVB, while I was away last week :(

Here is a tip from the Bean Forum.
