In able for the house fulfills its function, we need to eliminate some factors that disturb us in doing these things. Example is the insects. One of the easy ways to prevent insects is to use insect repellant. This is the reason why the researcher decides to make a liquid insect repellant. There are many commercially available liquid insect repellant in the market. The commonly used commercial liquid insect repellant in the Philippines is quite unaffordable and use chemical that may cause irritation. The researcher plans to use all natural ingredients in the liquid insect repellant in his study. Since the ingredient to be used is natural, the liquid insect repellant to be made is more affordable and environment friendly.
B. Statement of the Problem
