ABSTRACT
This study uses the extract of chili (capsicum Frutescens, variety of Capsicum
Annum) and Makabuhai (tinospora rumphii Boerl of the Crispamenaspermacea family)
plant to control pests in our house. The Makabuhai extracts contains bitter substance,
the principle colombine (2.22%); traces of an alkaloid; and a glucoside. Also contains an
amorphous bitter principle, picroretine and traces of berberine. While chili produce the
compounds called capsaicinoids, spicy taste and smell offensive to insects. The goal of
this research is to determine the insecticidal effects of Makabuhai (Tinospora rumphii
Boerl) stems and Chili (Capsicum Frutescens) extract. 200 grams of Makabuhai stems and
of Chili were gathered and pounded separately using mortar and pestle. After pounding,
the Makabuhai stems and Chili were soaked separately for 30 minutes with 60 mL of
water. Both mixtures were strained using a piece of cloth to separate the pieces of
Makabuhai stems and Chili from its extract. After processing its extracts, 5 mL of
Makabuhai extract was tested on 5 termites, the result showed that the termites died
slowly for more than 1 minute. Then, a separate 5 mL extract of Chili was also tested on
another 5 termites and the result showed that the termites did not die. Another
application was done, using the mixture of Makabuhai and Chili extracts, was tested on 5
termites. Spraying 5 mL of the mixture of Makabuhai and Chili extracts on 5 termites and
was observed that the termites died after 1 minute faster than the previous applications.
The same procedures were repeated three times and same results were observed. These
STATEMENT OF THE PROBLEM
The researcher of this study aims to discover the
insecticidal effects of Makabuhai and chili extracts as a
potential household insecticides.
The result of this study answers the following
questions:
• What is the insecticidal potential of Makabuhai
and Chili extract as household insecticide?
• What is the impact of Makabuhai and Chili
insecticide to the environment?
• What are the economic advantages of the
Makabuhai and Chili insecticide compared to the
commercial one?
SIGNIFICANCE OF THE STUDY
This study investigates the potential of the Makabuhai and chili
extracts combine together as a household insecticide against termites. The
mixture was made into a solution with little water and sprayed onto termites.
The results of this study can hopefully offer significant and effective
insecticidal potential of Makabuhai and Chili extract against termites to the:

GENERAL PUBLIC who can benefit in the eradication of these
destructive insects using an easy-to-make household insecticide;

INDIVIDUAL who wanted to have homemade and easy to prepare
insecticides since the Chili and Makabuhai are endemic plants;

ENVIRONMENT which will serve as an alternative insecticide to the
commercial ones which have destructive effects; and

FUTURE RESEARCHERS for possible references in future studies.
SCOPE AND LIMITATION OF THE STUDY
This study is delimited to
the potential insecticidal effect
of Makabuhai and Chili extract
against termites.
METHODS AND PROCEDURES
The researcher gathered all the necessary materials needed for the study including termites. All
materials were checked if they were clean and safe for using. To avoid being exposed to the solution, the
researcher wore gloves and goggles.
For the preparation of the extract, the researcher gathered Makabuhai and Chili, which were
brought by the classmates from their backyard gardens and some were collected from around the school
campus. Since Makabuhai and Chili are endemic plants in this place, the gathering was made easy and fast.
Then, the researcher weighed 200 grams of Makabuhai stems and were chopped into smaller
pieces. Afterwards, it was pounded using the mortar and pestle until it started to produce some extracts. The
same procedures were made by the chili. Both of the extracts were put inside a container separately. Poured
60ml of water to each container. The Makabuhai stems were soaked in 30 minutes to get the bitter substance
from it.
Both of the extracts were strained separately using a piece of cloth. The cloth was slightly
squeezed to get more extract from the two mixtures. It was observed that the gathered extracts from each
mixture is only 55ml each. There was a slight difference of 5ml to the water added to it.
Lastly, 5 mL extract of Makabuhai stems and 5 mL extract of Chili put inside an empty spray bottle
separately and another mixture of 2.5 mL Makabuhai extracts and 2.5 mL Chili extracts were mixed inside
another spray bottle. It was then ready for application. It was observed that the mixture has a distinct smell.
After processing its extracts, each solution was tested on termites in three times. The first test was
done using the Makabuhai extracts. Spraying 5 mL of the extract on the termites, it was observed for more
than 1 minute that the 5 termites slowly died. Another 10 mL of Chili extract was sprayed to 5 termites and
were observed that the termites did not die. The same procedures were repeated three times and same results
were observed. The last application was using the mixture of 2.5mL Makabuhai extract and 2.5 mL Chili extract
sprayed onto 5 termites. This time, the termites died in 1 minute only, faster than the two previous applications
done.

CONCLUSIONS
The researcher concluded that the mixture of
Makabuhai and chili extracts is an effective
household insecticide and a potential help in the
eradication of household pests like termites based
on the three different tests conducted three times.
Thus, this study offers an effective means of
lessening the destructive ants and termites yet
cheaper than the commercial insecticides in stores.
This study also offers an environmental-friendly
kind of insecticides and easier made kind because
the materials used can be found in our backyards
and gardens.
RECOMMENDATIONS
The researcher recommends the use of
Makabuhai and chili extract as an effective
household insecticide which is environmentally safe
and cheaper than the commercial insecticides in
stores and a solution in eradicating destructive ants
and termites.
To further improve the study, the researcher
also recommends thorough observation of its
effectivity by applying the insecticide to different
pests.
