There is a fungus that is approved to control ticks called Met52: https://www.novozymes.com/en/advance-your-business/agriculture/crop-production/crop-production-met52 https://www.novozymes.com/en/advance-your-business/agricultu... Novozymes took it off the market for tick control for some unknown reason a year or so ago, though it still seems to be available for aphid control. I had some applied to my yard a year ago, haven't seen any ticks since then, however I also eliminated places that mice nest in and had a lot of brush cleared. Been applying Damminex tubes as well.
