Welcome, Darren. I tend to shy away from any sort of packaged product and don't always trust the labeling. Here's an interesting article I found when researching Sluggo as I was fighting slugs on my ligularia:

It raised enough questions in my mind to bypass Sluggo. There are some battles worth fighting, others not. I live in a slug-infested area, they turn my ligularia into lace. I'm ditching the ligularia, as it is primarily a foliage plant for me (not that crazy about the blooms). I think your beans will have some slug damage but will produce plenty of beans for your table if you do nothing. But, that's your call.
I've had good success with beer traps, less success with copper. Best success seems to be plucking the slimy critters directly from the garden, disgusting as that is. Good luck.
