white fly infestation #388362

Asked March 11, 2017, 11:47 AM EST

Last year mid-summer I notice these very tiny white insects in my vegetable garden. they increased over the summer and by fall covered most of that bed which contained cukes, squash, eggplant, broccoli, & peppers. There was also a heavy odor of mildew from the bed by the end of summer. Now the soil is dusty, sand like in texture and coats everything it comes into contact with a powdery black. My questions is: Should I remove & replace all the soil in this raised bed before I plant this spring? I researched "white fly" and it is apparently very hard to get rid of. I do not use pesticides in my garden. thank you for any suggestions you can provide
