Are there any natural ways to kill lawn ticks?

Get some nematodes, s. felitae are the ones you want. I've heard you can find them at garden centers, but I've had no luck so far. It's easier to find them online. http://www.arbico-organics.com/1220310.html I'm gonna try a mixture of garlic powder and cinnamon. Fleas and tick hate garlic powder and ants hate cinnamon. I'll let you know how it goes. Take care and good luck! Thanks for looking for natural options!
