My LO's nanny actually places 蚊香 and diffuse lemongrass EO in the house for this Zika period, anyone could tell me if it is suitable for my 5.5mths old LO to sniff it everyday just like that? As there is a bedridden elderly and my LO in the house, so they are kind of kiasu in putting one 蚊香 each in each room and living room. My LO is currently staying there overnight.
