I have a question about flies in my garden. I think I made a great environment for them with my awesome compost. I think there are larvae in the compost that are hatching into flies that are harming my zucchini plants. They are small flies that look like fruit flies that I looked up on the internet. I saw a post recently where someone covered a garden bed with mosquito netting to keep flies off the onions. My garden is quite large and I cannot cover it up. Now that is is planted, is there anything I can put on the soil to kill these pest, or do I have to wait till after harvest? If so, what do I use to kill them off so they don't hatch again next year? This week I have been using diatomaceous earth, cayenne pepper, and I even resorted to sprinkling "Seven" around the zucchini plants. I do not want to lose my crops to these pesty flies. If anyone has advice on what I should use, when to use it, and how to use it to kill these critters, I would be very grateful.
