Bought this because I wanted a more natural product for my family and didn't want the awful smell of regular bug spray. This product is great! The smell is great and doesn't require washing clothes immediately after wearing, it is just as effective (if not more) than traditional products with DEET, and though more expensive is well worth it!
I'm pretty sure it will repel any humans, including your friends, that can smell. If vanilla extract were to smell bad, then Repel is what it would smell like. So the smell, it stays on on your skin for seemingly 2 hours or before you get it washed. But on clothes...Ha! you need to send those into the washing machine if you accidentally get the stuff on fabric. The next time I use this repel thing I'm going to mix it with water, in hopes that it will dilute the smell but still keep the mosquitoes away.
