ABSTRACT
This research is entitled NATURAL MOSQUITO REPELLANT conducted by KAYE ANGELLIE C. NAPIGKIT of Lanao Chung Hua School. One problem of today especially with regards to health is the disease caused by mosquito. Mosquitoes are a family of small, midge-like flies, the Culicidae. It is said to be the most dangerous species on earth. It carries virus that can cause malaria and dengue. Dengue is transmitted by several species of mosquito within the genus Aedes. And to get rid of this species, Splash Corporation invented of a mosquito repellent (Off Lotion) to drive away mosquito. The researcher would like to come up with an alternative repellent that is as effective as off lotion or better in a natural way. Moreover, the researcher also considered if this alternative repellent is cheaper than buying an off lotion. In line with this, the researcher investigated which between off lotion and the researchers experiment is better in driving away mosquitoes.

THE PROBLEM AND ITS SCOPE

Background of the Study

Mosquitoes have complex methods of detecting hosts and different types of mosquitoes react to different stimuli. Most mosquitoes are active at down and dusk, but there are also mosquitoes that seek hosts during the day. To avoid being bitten, make sure that you aren’t attracting mosquitoes, using attractants to lure mosquitoes elsewhere, using repellent and avoiding act, ions that diminish the effectiveness of the repellent. Garlic is an important medicinal herb that is readily available everywhere, unlike some of the other herbs. Garlic does indeed have scientifically-proven medicinal properties.  It contains a substance called Allicin, which has anti-bacterial properties that are equivalent to weak penicillin.  It appears that cooked garlic weakens the anti-bacterial effects considerably. Garlic is sometimes used for athlete's Foot, ear infections, HIV support, vaginitis and yeast infection, with less supportive data. Garlic is considered a topical antibiotic, but it is unclear if garlic possesses any antibiotic activity when taken internally.

Scope and Limitation
This study will be conducted in the residence of the researcher. The subject of this study is to test the effectiveness of garlic as a natural mosquito repellant. The garlic that will be used for this study will be taken from the researcher’s residence.

Objective of the Study
This study seeks the effectiveness of Garlic as a natural mosquito repellant. Specially this intends to: 1. Know how effective is the garlic as a mosquito repellant
2. Suggest to people a garlic as a mosquito repellant

Definition of Terms
Culicidae – a family of slender, Orthorrhaphous dipteran insects in the series Nematocera having long legs and piercing mouthparts. Stimuli – a detectable change in the internal or external environment. Foliage – an ornamental presentation of leaves, stems, and flowers, especially in architecture. Lactic Acid – is a chemical compound that plays a role in various biochemical processes.

RESEARCH METHODOLOGY

Gathering of Materials

These are the things needed in making the Natural Mosquito Repellant, First is the Garlic that can be found in the market. Second is the oil that can be found also in the market. Third is the small bowl that can be found in the researcher’s residence. Fourth is the Pyrex Ware that can be found also in the researcher’s residence.

Preparing the Materials and Equipment
Smashing the Garlic, Washing the small bowl and Pyrex Ware, Boiling the water.

Making the Garlic Oil
First smashed the garlic. Second put the smashed garlic into a small bowl with oil. Third pour some hot water in the Pyrex ware and place the small bowl. Fourth wait for 10 minutes then after 10 minutes separate the smashed garlic.

RESULTS AND DISCUSSION

Results

Mosquito Repellents

Results

Implications

Off Lotion
The mosquito repellent was effective.
There were mosquitoes but less than mosquitoes without Off lotion.

Garlic Oil
The mosquito repellent was effective.
There were still mosquitoes but fewer than those with off lotion.

Discussion
The first row shows that using off lotion is effective mosquito repellent rather than not applying off lotion. But compared to Garlic oil mosquito repellent, there were still mosquitoes but fewer compared to those with off lotion. Between the two repellents, garlic oil mosquito repellent is much effective than off lotion.

SUMMARY
The Garlic Oil and Off Lotion were applied within 5 days. The water with Off Lotion had many mosquitoes, while the water with Garlic Oil had fewer mosquitoes.

RECOMMENDATION
The Garlic Oil is recommended because it protects us from malaria and dengue. This mosquito repellent is effective because there would be less mosquito bites. It is not expensive because the materials that can be used in making the mosquito repellent can be found at home.
