Repellent</a>&nbsp;wasn't doing the job for me, I tried to find something better. Boundary makes strong claims, but ultimately it's the same product as Keep Off. From the label, it's clear that at least 2% of the ingredients are the same, but the undisclosed "other ingredients" might not be different either. Both products smell the same. The active ingredients are the same. A close look at the labels shows that out of the many paragraphs of text, most are the same word for word.
