There probably aren't many people here who have a fear of snakes. Comments sections on YouTube videos might be a good place to get hints (though beware of commenting bots -- you can get answers to your questions, but bots will repeat some of those answers so simply because half the responses are "Eww, they look slimy" doesn't mean that half of people think this).
There is a lot of published research on this sort of thing -- searching Google Scholar would be a good place to start.
Keep in mind there's a distinction between a phobia and a general fear. Researching the former will lead you into some pretty technical papers, while the latter is possibly more what you're looking for. On the general fear, here's a paper that looks pretty interesting and ties in a bit with some other discussions that have been ongoing here:
