Chapter I: Introduction A. Background of the Study:
Nowadays, people depend on the commercial insecticides that are expensive and less effective. Based on my research that the Makabuhay and Chili Extract can be substituted as an insecticide in our house. This study uses the extract of Chili and Makabuhay plant to control pests in our house. The Makabuhay extract contains bitterness and the Chili produce spicy like taste and smell; it is possible that this taste and smell is somewhat offensive to the Insects.

An ant lives everywhere on land, being the most numerous in insect species. They live on underground and create those earthier mounds. Some lives on trees and some on hollow parts of certain plants. They can be considered as a menace in our kitchen and dining hall.
Cockroaches have been a problem to many of us. They may contaminate our food with the filth they carry, and causes sickness.

And it's so hard avoiding these things because they come and go whenever, wherever.
These insects are pests once they are allowed to multiply. To control these pests, chemical insecticides are usually used in many of us but there are many harmful effects in using those chemicals. Among those are dangers they threaten on our surroundings. It causes and adds to pollution.

Some plants produce a distinctive chemical or odor that can drive away insects. Realizing the good potential of these plants in controlling insects, botanical or organic materials are used now, being considered instead of wide spread use of chemical ones. Since some of these plants are commonly growing in our backyards, they are inexpensive and environmental friendly.

B. Statement of the Problem:
Which is more effective the Makabuhay and Chili extract or the garlic and black pepper extract?

Sub-problems: 1. Is it effective? 2. Is it eco-friendly? 3. Is it easy to locate the materials?

C. Significance of the Study
This study investigates the potential of the Makabuhay and chili extracts combine together as a household insecticide against ants and cockroaches. The mixture was made into a solution with little water and sprayed onto ants and cockroaches at varying concentrations. A person who is afraid of cockroaches has a solution to their problem which they can find in their house.

The people who will benefit from this home-made pesticide are the following:
1st is myself because I hate cockroaches and its weird when it land on your skin.
2nd is people who hates cockroaches or any insects/pests.
3rd is my family and relatives because so they will not have a hard time to buy expensive pesticide so they can make it in their house.

D. Scope and Limitations of the Study
The aspects that were covered of the topic were the problem of the pests going in and out to the house. And some people are afraid of cockroaches and etc.

It may take to 6 to 8 weeks to conduct the study.

The limitations of the study that the researchers should know are that the experiment should not be harmful to the people nor to the person who did the experiment and not harm the plants and animals.

II. Review of Literature: A. Review of Literature
When I searched Google there are some related topics about the insecticide. I found out that the Makabuhay plant and Chili can be an alternative insecticide in our house because the materials are easy to find and it is very cheap.

Hot Chili
Hot chili pepper (capsicum Annum) sweet and spicy (fructose’s Solanceae) belongs to the same botanical family as potato, tomato, eggplant and tobacco. They are thought to have been used first in México around 7000 BC; Columbus brought them to European 15th century. Peppers made their way around the world and were brought to North America with European colonists chili peppers are found in abundant and cheap on Philippine market. Chili pepper plants are decorative in your garden or home. Chili pepper plants grow in tropical or subtropical climate zones. Makabuhay Plant
Makabuhay plants ( tinospora Crispamenaspermacea) is a woody climber up to 15m long, older stems with numerous prominent protrusions, leaves broadly heart shaped, flowers with 3 petals, fruit an ellipsoidal drupe. Orange up to 2 cm long. Its stem contains a very bitter milky sap. In primary rainforest or mixed deciduous forest throughout the Philippines. In tropical area at altitude up to 1000 m. Bitter taste is not agreeable to most people. B. Hypothesis
I, the Researcher, hypothesized that my homemade insecticide which is the Makabuhay plant and Chili Extract: can be a alternative insecticide in our house.

C. Definition of terms: 1. Eco-friendly- it means Environment-friendly (also eco-friendly, nature friendly, and green) are ambiguous terms used to refer to goods and services, laws, guidelines and policies claimed to inflict reduced, minimal, or no harm at all, upon ecosystems or the environment. 2. Inexpensive- not costing a great deal; cheap.

Antonyms: expensive 3. Insecticide- a substance used for killing insects. “the use of chemical insecticides"
III. Methodology A. Research Design:
The design of my experiment is that to help mother earth because the materials that I’ll be using can be found in our house or our community.

The Control is the Makabuhay plant and the Chili Extract while my experimental is the garlic and the black pepper extract.

B. Materials:
MATERIALS: Chili (300g)
Makabuhay Stems (300g)
Mortar and Pestle
Beaker

Piece of Cloth
Spray Bottle
Stirring Rod; Water C. Procedure:
PREPARING FOR THE CHILI EXTRACT:
1.) Collect enough hot chili at least 300g.
2.) Pound them with mortar and pestle.
3.) After the juice is extracted, add 25ml of water.
