Citronella is supposed to work however I used to live in a heavily infested area of mosquitoes -summer and winter, day and night. I found burning citronella, or even planting the plant did nothing.
Although the council used helicopters to spray often, there were still mosquitoes all the time, and nbight time I just stayed indoors.
I read once that vitamin B tablets stop mossies from biting you, so I took this for the 10 years I was on acreage. I don't think I ever got bitten, yet my partner had Ross River virus, and he didnt use the Vitamin B tablets.
I have since read that this is a myth, however it seemed to have worked in my case.
