dilemma called dengue. Dengue is a deadly disease that can be spread through a bite of
mosquito called Aedes Aegyptus. The symptoms of dengue include high fever, severe
headache, joint and muscle pain, vomiting, skin rash and mild bleeding.

REVIEW OF RELATED LITERATURE AND RELATED STUDIES
This chapter represents the comprehensive review of related and significant
literature and studies conducted here and abroad. The reviews had been used as baseline
in developing the study.
Related Literature
Moises Angelo Gabuntin (2009) affirmed that oregano is the name given to several
species of plants whose leaves when dried impact a particular flavor to food. The essential
oil of oregano is a powerful anti-microbial and has even been tested and used at K-state
to sterilize plant cell cultures in tissue culture experiments. In these trials, oregano oil
was strong as chlorine bleach .It can be considered as mosquito repellant.
New Tech Bio (2015) determined that Lemon grass is very popular and used for
medicinal, food and insect repellant products.
Edmon Agron (2008) defined that lemon grass is a genus of about 55 related grass
species or varieties. Lemon grass has insecticidal properties and the extracted oil is used
in insect repellants and insecticidal sprays.
Helmenstine (2011) identified that insect repellant is any chemical or natural,
that causes insects to make directed, oriented movements away from the source of
repellant. And lemon grass can be used as natural insect repellant.

RESEARCH METHODOLOGY
This chapter presents the research design, materials, procedures, data collection
and statistical treatment necessary in the analysis of the data.
Research Design
The researchers make use of experimental method. The experimental method
involves manipulating one variable to determine if changes in one variable cause changes
in another variable. This method relies to control variables, random assignment and the
manipulation of variable to test a hypothesis.
Population and Sample
In this study, the researchers had used simple random sampling to determine the
sample. Data was gathered from 15 respondents including the owner of such households
as well as teachers of Burgos National High School who have their own classroom.

oregano and lemon grass mosquito repellant very pleasant. While, seven or 46% of the
respondents rated it pleasant, four or 27% of them rated it moderately pleasant and
one or 7% rated it unpleasant. Furthermore, none or 0% of them rated it extremely
pleasant.

Oregano and Lemon Grass, pleasant.
2. The 300 grams of oregano leaves and another 300 grams of lemon grass in
350 ml of water is highly effective in making mosquito repellant.
