I use mosquito coils, they are very effective.
I also have an electric bat, although it’s more for the phycho fun of killing than helping reducing bites. They are just too many.
I tried lemongrass as a natural deterrent but had the impression it made no difference.
What works best for me is: slapping those you can while not caring about the rest. Because once you start to scratch it’s a vicious cycle, so I don’t touch stings and usually then forget about them shortly after.
Someone, who ridicules people for some characteristic while they are in the process of improving that characteristic, has understood so little about life.
