My aunt was a huge gardener before she became to old to handle all that, she's 95 now but they had their garden inside a fenced in area to keep critters from eating their vegetables. She was all about growing stuff organic so I don't know what she did about bugs. I know when it came to Japanese beetles they hung these little bags in the trees that attracted then trapped them inside. I always remembered her telling me to never start growing green beans until late June because their was a certain bug that would attack them if you planted them earlier. I use to use that Seven's dust if something was eating my stuff but now I am even more hesitant to use that because of the lack of bees problem. So unless something is taking something right down to the ground I will use it very sparingly.
