If you are looking into using a mosquito repellant, you are probably wondering how it is that they work.  Some people might think that a mosquito repellant will actually kill mosquitoes that try to bite you.  Actually, repellent does just that; it repels the insects from your skin.  Most repellents contain DEET, which is a chemical that hides the natural scent of your skin, to which mosquitoes are attracted.

You can find mosquito repellant in many forms, from spray-ons and foams to roll-ons and creams.  Be sure when you are purchasing a repellant that it contains DEET.  The amount of DEET that the product contains will affect how long it protects for.  The higher the concentration of DEET, the longer the product will work.  If you are in an area where you will be getting wet, you may need to reapply more frequently.

The use of DEET in mosquito repellant has proven to be fairly safe, with skin irritation being the most common side effect.  You may also want to combine wearing a repellant with wearing long socks, pants and long sleeve shirts when outdoors.  You can also use mosquito netting around your campsite or tent for more protection.
