DEET is best if avoided. It can melt plastic, so why on Earth would we want to put it on our skin, let alone our children’s skin?! Herb-based products are more gentle. Some ingredients might include: eucalyptus, citronella, lavender, and tea tree oil. You can even make your own recipe by looking online to find one that best fits your family. If you do get bitten, put a drop of peppermint oil to soothe the spot.
