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
Is it possible to make an effective liquid insect repellant out of the cacao (theobroma cacao), lansones (lansium domesticum), garlic (allium sativum) and eucalyptus? If it’s possible, how is the price and effectiveness of it comparing to the commercially available one.
C. Significance of the Study
The study is significant to the people who want to protect their house and their love ones against insects specially those who can’t afford the commercially available insect repellent which use chemicals. D. Scope and Limitations
