Make a natural tick repellent. -- Create a citrus based repellant. Ticks avoid citrus, which makes it an effective weapon. To make: Boil 2 cups of water, and add two chopped lemons, limes, oranges, or grapefruit—–alone or in combination. Let it boil for a minute or so, then simmer the concoction for an hour. Strain the fruit out, let it cool, pour into the sprayer, and squirt. Other natural repellents use geranium, lavender, or peppermint essential oils.
