I'm not aware of anything. There was an interesting episode of Sliced Bread on BBC Radio 4 recently about mosquito repellants. Basically DEET or PMD is as good as it gets, but applied incorrectly makes it ineffective. Citronella is pretty much useless. https://www.bbc.co.uk/programmes/m001np5v https://www.bbc.co.uk/programmes/m001np5v
