Introduction
In Malaysia, where mosquito-borne diseases like dengue, malaria, and chikungunya are a constant threat, using the right mosquito repellent is more than just a comfort—it's a necessity. With tropical weather ideal for mosquito breeding, knowing how repellents work and which ones are effective can help protect your home and health.
Why Mosquito Control Matters in Malaysia
High Dengue Risk: Over 123,000 dengue cases were reported in Malaysia in 2023 alone.
Ideal Climate: Warm, humid environments promote year-round mosquito activity.
Urban Areas at Risk: KL and Selangor frequently top the list for dengue hotspots.
Key Insight: Preventing mosquito bites reduces your risk of serious illnesses transmitted by the Aedes and Anopheles mosquitoes.
How Mosquito Repellents Work
Mosquito repellents don’t kill mosquitoes. Instead, they mask the human scent, mainly carbon dioxide and lactic acid, that attracts them. The repellent interferes with the mosquito's sensory system, making it hard for them to locate you.
Ingredients That Work:
DEET: Strong and long-lasting protection.
Picaridin: Odourless and effective alternative to DEET.
IR3535: Found in some skin-safe products.
Lemon Eucalyptus Oil: A natural option that’s surprisingly effective.
Types of Mosquito Repellents in Malaysia
1. Topical Repellents (Creams, Sprays, Lotions)

2. Electric Mosquito Repellents
Plug-in devices that emit repelling vapour.
3. Mosquito Coils and Mats

Understanding the Mosquito Life Cycle
Egg: Laid on stagnant water
Larva (Larva Nyamuk): Lives in water
Pupa: Transitional stage

Natural vs Chemical Repellents: Pros & Cons
Type | Pros | Cons |
Natural | Eco-friendly, skin-safe | Less lasting protection |

Common Myths About Mosquito Repellents
MYTH: Mosquitoes don’t bite during the day.
FACT: Aedes mosquitoes are active in the daytime.
MYTH: Ultrasonic repellents work on all mosquitoes.
FACT: Scientific studies show limited evidence.
Real-Life Insights: How Mosquito Repellents Actually Work
Research shows that female mosquitoes are drawn to the carbon dioxide we exhale, lactic acid in our sweat, and various skin odors. These attractants make us ideal targets for bites, especially in Malaysia’s warm and humid environment. While physical barriers like mosquito nets work well in small spaces, repellents offer a more practical solution for larger or outdoor areas.
DEET and picaridin are the most effective ingredients in mosquito repellents. DEET works by disrupting the mosquito’s ability to detect human scent, while picaridin offers a nearly scentless, equally potent alternative. Though natural options like citronella are popular, studies have found them significantly less effective. For reliable protection against mosquito-borne diseases in Malaysia, science-backed repellents like DEET or picaridin remain the best choice.
Did You Know?
Female mosquitoes are the only ones that bite.
A mosquito's average lifespan is 2 to 4 weeks.
Red clothing attracts mosquitoes more than light colours.
Conclusion
Mosquito repellents are essential for every Malaysian household, especially in dengue-prone areas like KL and Selangor. Understanding how they work, choosing the right type, and pairing them with preventive measures can keep your family safe and bite-free.
