I'm guessing that you have just done your trip to KAB?.....
Mate if Bushmans ain't working nothing proberbly will...........detol and baby oil is the prefered concoction.......1ltr oil......100mm detol...keep applying...generously.As you know the oil creates a barrier and the detol disefect's the wound.
Luckily i'm usually the one sitting around the camp in shorts only wondering what all the fuss is about.
Did you try lot's of xxxx gold?......works a treat.
Make sure you treat the bites with some savlon or similar they can get badly infected......Years ago my mates mother nearly lost her whole foot due to a sandfly bite infection gone septic.........she had 1/4 of her foot removed to save the foot.
