Making soap is a do-it-yourself endeavor; however, you need some special equipment and ingredients. The main components of homemade soap include water and lye, or an acidic product that reacts with essential oils to produce soaps.

You will need a way to melt down a large volume of lye and oils, as well as molds to set the soap until it hardens. It is advised to use special molds, tools, and other vessels, especially for your soap making. Do not mix the tools you use to cook with soap-making tools.

Another easy way to use soap to deter mosquitoes is to set up a shallow dish of soapy water. This dish will attract the mosquitoes to its sweet and soapy surface, only to coat the mosquito’s legs with dish soap bubbles, effectively trapping it in the soap where it will die.
