Mosquito repellent

[solidstars]

my son has G6PD so we have to be quite careful about the mosquito repellents (camphor etc) so we mainly use the ones with citronella. johnson's has a liquid (rub on) repellent that we got in bangkok (surprisingly not available in hk?). the bottle is green

Can anyone recommend a cheap place to buy the mosquito patch? I've seen them at Sasa, can't recall the price, but it seemed expensive for three patches. Thanks!
