How to remain safe while collecting??

I live in the North-western corner of Louisiana, in the Shreveport/Bossier area. I would love to do some field collecting to see what I can find, but I have a major concern. I was told by a local herper that the ratio of snakes found in the area was 3 hots for every 1 non-hot. So my question is this...how do I protect myself and remain safe while field collecting for non-venomous snakes when I am 3 times more likely to find the hot snakes??

I am very cautious and by no means reckless in any sense. I don't go around just flipping over rocks and logs, but I do like to explore areas where snakes would be likely found. I don't currently have any hooks or tongs, would it be wise to invest in a set?

Thanks for the advice!
