Ticks...bloodsucking, disease-spreading parasites. Unless you are looking for Lyme disease, there is no positive to having a tick on your person.
Here is a quick and easy homemade repellent safe to use on the whole family.
In a spray bottle, mix 2 cups of 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 favourite 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 repel ticks. After mixing the solution, spray onto clothing, skin, and hair before going outdoors. Reapply every four hours to keep ticks at bay.
Even if you are using the tick repellent- be sure to give yourself a good "tick check" every day.
