I'm showing my ignorance here, I know, but is it necessary to spray deet based insect repellant over your clothes or should you just spray on to exposed skin? I asked this question on another forum and was told that you can spray it over clothes but i wondered if it is really necessary. I know that you shouldn't apply under clothes and i assume that's because it is less effective?
Would appreciate some guidance from regular travellers/ contributors as it's my first time to this area. Thanks.
