Tick Repellent for Humans:
A simple homemade repellent can be made with a few inexpensive household idgredients. In a spray bottle, mix 2 cups distilled white vinegar and 1 cup of water. To make a scented solution so you do not smell like bitter vinegar all day, add 20 drops of your favorite essential oil or bath oil. Eucalyptus oil is a calm, soothing scent that also works as a tick repellent, while peppermint and citrus oils give off a strong crisp scent that also repels ticks.
After mixing the solution, spray onto clothing, skin and hair before going outdoors. Reapply every four hours to keep ticks at bay, and examine the skin and hair when returing home to make sure no ticks are on the body.
Hope this helps.
