Sand flies spray or cream

Deet is best but some smell better than others. I did try some organic citrus based repelants that are quite good against sandflys but atract bees

Thanks geeves.

I'm using "OFF!" Tropical (the orange one) it is using Picaridin which is much less aggressive than DEET (as in: doesn't dissolve your ropes and clothes!) and still efficient enough. It is also the cheapest available in NZ, when you compare the price per litre: https://shop.countdown.co.nz/Shop/ProductDetails?stockcode=729772 Because it is a simple spray you can repack it in a smaller container when going tramping. I use a 50 ml bottle for that.
