Hello. For the past several years my yard has been infested with chiggers. The grass is trimmed. Leaf debris has been removed. Yet they even find me when I'm sitting on the concrete patio in full sun. I do have some mulch in a trash can and I wonder if that might be a breeding ground. That said, they seem to be present throughout the yard. Are there methods I can employ that without going to full on pesticide? Something that is also food safe as they have in past years made themselves at home even in container gardens. Any suggests welcomed as they pretty much rule the yard from now through Fall. Thank you.
