Probably not the greatest choice for extreme conditions
I did a lot of volunteer work in the Peruvian Amazon and in Thailand last year and didn't want to put deet on my body every day. Avon Skin So Soft helped a little, but I still got bit. There were A LOT of mosquitoes though (swarms) so it makes sense that a non-deet product can only do so much under those circumstances. I've used it in areas where there are not too many mosquitoes and felt it worked pretty well.
