The only type of repellent that is proven to work is repellent containing DEET. Keep the doors and windows closed so that the mozzies don’t fly in. Use a mozzie net if your baby is sleeping in a baby cot. Dress baby in light coloured clothing that covers as much skin as possible eg pj onesies.
farlin and california baby good....patches also useful...you can try the brands available in your nearest supermarket......most of them decent. tr using net if possible
I use natural repellent spray and diffuser. Sometimes if it gets worse, i will stick a mosquito patch on their clothing.
What about essential oils? They are natural and not harmful. Do use with caution if your lo is very young though.
close all windows n toilet window panels at 5pm onwards....
