My winter and summer squash is being invaded by squash bugs. I have dusted with Sevin powder many times. But I am starting to lose vines and plants now. My plants are on black soft plastic and the bugs are very easy to see. So should I let my ladies out of their pasture and into the garden?? I have about 60 tomato plants with semi ripe tomatoes, and I am not sure if they will be targeted by the chickens or not. Any suggestions....
