HELP! The past 2 years has seen a huge uptick in invisible biting insects around my vegetable garden. I've tried to trap and indemnify them, but unsuccessful, only catching lizards:-( . They come out only in the summer months. They are not mosquitos. They are tine, I don't see them when watering my veggies, but they somehow crawl up my pants, under my shirt, up to groin area, under arms and knees, all over really, biting, which show up the next day as red itchy welts, which take 5-7 days to go away. It's gotten so that I no longer want to visit my raised veggie patch, which has been my passion for years. So sad! I tried spreading diatinacious earth, but did not reduce them. I've tucked pants into socks and sprayed DEET on close, which had limited success. I've tried wearing a Hazmat suit into the yard, but that is not a long term solution I've finally had enough and now ready to nuke them. Please advise what insect poison I can safely spray on ground around the garden to kill them off, and how to safely apply and how often to apply. I desperately want to get back to the pleasures of gardening, rather than sequester myself inside, itching and scratching. Thank you.
