My friend has a recipe that acts somewhat as a deterrent for mosquitoes (I have an infant, and do not want to put any type of bug spray on him). It will not work as well as the other products, but is another option.
Base: witch hazel (fill spray bottle half-way with this liquid)
Add: 3-5 drops of citronella pure essential oil
Add: 3-5 drops of peppermint pure essential oil
