Here is an effective home made repellent against mosquitoes and flies!

You need cheap cooking oil, shampoo, and 9% vinegar. Mix these ingredients in equal quantities and stir them thoroughly until you see white foam. You can spray this concoction on your body or pour it into a container and leave it open. The vinegar scares away insects, the shampoo hides the strong smell while the oil is the base of any cream. This repellent is safe for children and doesn’t have a strong smell.
