Create a citrus based repellant. Ticks avoid all citrus plants, which makes citrus an effective weapon. To make a citrus based repellent: Boil 2 cups of water, and add two chopped lemons, limes, oranges, or grapefruit. Let it boil for a minute or so, then simmer for an hour. Strain the fruit out, let it cool, pour into the sprayer, and squirt it on you, your kids, your pets, your yard and anywhere ticks might be found in your yard.
