Keeping a DIY tick repellent on hand for your family to use makes good sense because ticks suck. Literally. I’m saying these little buggers attach to your skin, use their tiny tick mouths to latch on, burrow into your skin, and suck the blood out of you. They are nasty critters. Their bites are painful and they cause disease. Therefore, applying repellent before you spend time outdoors in the summer is a must!
