Mosquitoes are attracted to carbon dioxide - something we all emit. Some people emit more than others and are simply easier to find. Personal mosquito repellents work by masking your odour and making it hard for a mosquito to find you. This recipe essentially masks the entire area the diffuser covers. Importantly, you know exactly what is in it because you made it yourself.
Add all essential oils to a large capacity diffuser. I set it to mist intermittently, 30 minutes on, 15 minutes off.
Apart from knowing exactly what is in your diffuser (ie: no fragrances and chemicals), you are avoiding open flames with candles that may also contain unlisted toxic chemicals and palm oil.
