I'l likely be camping in some fairly leech infested locations over summer. Does anyone have any tips for securing a campsite against intrusion? Mainly the small circle where I have the fire and sit while cooking/relaxing etc. (My tent has an inner so no worries while sleeping). Its fairly annoying to be relaxing at the end of a days walking to find a family of leeches has slithered up and started snacking on my legs/torso.
Some ideas I had.
- bringing a small bottle of salt and making a ring. This also apparently works for bull ants which are annoying when they bite you on the a$$ while your enjoying a brew

Need to be careful there isnt already leeches inside the ring.
- Liberal spraying of DEET over all areas of body/clothing that will be in contact with the ground. Its what I currently do but Id rather not do this as I try and limit chemicals and it doesnt stop the leeches from sliding up right next to me.. seeing 1/2 a dozen within a few cm doesnt make for a relaxing campsite evening if they aren't actively biting you.
Ideas / tips appreciated.
