Mosquito-borne illnesses like malaria, dengue, and chikungunya continue to be major health threats across India, especially during the monsoon and post-monsoon seasons. Mosquito repellents offer an essential layer of protection, but with a wide range of products available—from chemical creams and vaporizers to natural essential oil blends—how do you know which one is right for you and your family?
This guide compares chemical and natural repellents, explains their permissible usage, and highlights safety guidelines for children.
🔬 Chemical Mosquito Repellents: DEET, DEBA, and More
1. DEET (N,N-Diethyl-meta-toluamide)
Overview:
DEET is globally recognized as a gold standard for mosquito repellent efficacy. It masks human scents that attract mosquitoes, making it highly effective.
Concentration and Efficacy:
- <10% DEET: ~2 hours of protection
- ~24% DEET: ~5 hours of protection
- 30% DEET: Optimal balance of protection and safety
- Higher concentrations: Marginally longer protection, but increased risk of side effects
Usage in India:
- Rare in Indian retail products but available in imported repellents or military-grade kits.
Child Safety Guidelines:
- Ages 2–12: Use DEET concentrations ≤10%
- Infants <2 years: Consult a pediatrician
- Avoid hands, mouth, eyes; do not allow children to self-apply
- Do not use on broken or irritated skin
- Wash off after returning indoors
2. DEBA (N,N-Diethyl-benzamide): India’s Common Alternative
What is it?
DEBA is the active chemical used in most Odomos products, specially developed in India to provide effective protection in tropical environments.
Efficacy and Concentration:
- 10–12% DEBA in Odomos products
- Offers up to 8 hours of protection
- Effective against Aedes, Anopheles, and Culex mosquitoes
Child Safety & Usage:
- Above 2 years: Safe to use
- Under 2 years: Use only under medical advice
- Apply only to exposed skin
- Avoid near eyes, lips, or cuts
- Reapply after heavy sweating or washing
- Conduct a patch test on first use

🌿 Natural Mosquito Repellents: Plant-Based & Essential Oil Options
Many parents and sensitive users prefer natural mosquito repellents. These use essential oils like citronella, clove, eucalyptus, and lemongrass.
