Natural Way to Kill Mosquito

We would like to express my special thanks of gratitude to our teacher, Teacher Carmen Blanco, as well as our principal, Sister Rita Devasahayam who gave us the golden opportunity to do this wonderful project on the topic “Natural Insect Repellent” which also helped us in doing a lot of research and we came to know about so many new things. We are really thankful to them.

Secondly, we would also like to thank our parents and friends who helped us a lot in finishing this project within the limited time.

We are making this project not only for remarks but also to increase our knowledge. Thanks again to all who helped us.

One of the easiest ways to prevent insects is to use insect repellant. This is the reason why we decide to make a liquid insect repellant for our Science Investigatory Project. 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 uses chemicals that may cause irritation. We plan to use natural ingredients in our Science Investigatory Project. Since the ingredient to be used is natural, the liquid insect repellant to be made is more affordable and environment friendly.

2. Statement of the Problem

Is it possible to make an effective liquid repellant out of cacao leaves, garlic, vegetable oil, and eucalyptus oil? If it is possible, how is the price and effectiveness of it comparing to the commercially available
