Demolished in what way? Bitten off to the near the ground? That could be deer. Holes eaten in all the leaves? ANy number of insects do that (likely Japanese Beetles in my neighborhood).

Defining demolished (or posting pictures) would help.

(Pole Beans)It seems that they are being ate half way up the stalk, not by the ground at all. Bush beans there are some of the leaves that have small holes and partial leaves. it s not deer b/c i'm not seeing any kind of tracks in the soil(square foot gardening very loose soil). demolished meaning they were looking good and i came out the next day and they were destroyed my pole beans were just hanging off the strings where something had ate the stalk, my bush beans looked like sticks with very few sparce leaves left- now i have planted beans in 4 different areas of my garden 2 spots are for starters so i can later transplant and 2 for production and all the starters are still looking alright at the moment. the bush beans that are being ate are right in the middle of my broccoli & cauliflower and they are not messing with broc & Cauli at all.??? and i've checked during the day for bugs ( not at night) and have not seen anything crawling.

My guess would be rabbits.

I have a woodchuck that has lived under my shed for 4 yrs. now. He had himself a great time with my peas and beans. I think he thought I left him a smorgasborg. Both were eaten half way down the stem.

i'm 99.9% sure that it is not a rabbit (finally got a dog so they stop breeding in my back yard) rabbits were the issue last year. - i was almost wondering about a woodchuck - since the incident is only isolated to my beans directly the only rodent i could think was a woodchuck hence there always in the bean field- or still some type of bug - i'm really trying to do this as organically as possible. i really just dont want to start putting any pesticides on anything, plus have a 5month old baby so this is where his veggies are comming from. thanks for any insight.

what about moths like the tobacco/tomatoe hornworm? i have just started finding a couple of these on my peas and pole beans last couple days and they can do some damage. here is a link on them. http://entomology.ifas.ufl.edu/creatures/field/hornworm.htm
