I have taken this spray on holiday abroad twice this year, and the most recent trip was to Africa on safari. I used it liberally every day and didn't get bitten once. I also used it in the evenings when most biting creatures are out and again no bites. It is a very safe and much more pleasant alternative to insect repellents and, in the heat, it is also very refreshing. My daughter is off to Thailand soon so I'm making sure she has some in her suitcase. Definitely one for the suitcase!!
