Mousti K.O. Duo combines a high-performance DEET-free mosquito repellent lotion—effective for up to 7 hours—with a soothing organic roll-on made with essential oils. An essential duo for tropical and mosquito-infested areas. It protects, soothes, and is gentle on the skin—even children’s skin. A complete, natural product for the whole family that you can take anywhere.
When traveling to the tropics or living in a mosquito-infested area, it’s essential to protect yourself effectively. That’s exactly what this combination of Mousti K.O. mosquito repellent lotion and organic soothing roll-on offers. Together, they form an essential duo for tackling the most mosquito-prone environments. The protective lotion is designed to effectively repel mosquitoes, including the most feared ones like the tiger mosquito (Aedes albopictus) and those that carry serious diseases such as malaria or dengue fever. It provides a protective barrier on the skin for up to 7 hours without using DEET, making it gentler on the skin.
What sets this lotion apart is that its effectiveness has been scientifically tested on the main mosquito species: Aedes, Anopheles, and Culex. In other words, it does more than just mask body odors: it acts as a true repellent shield, thanks to its key active ingredient, IR3535, at a 25% concentration. This molecule is well-tolerated and recommended by the WHO for preventing bites in tropical areas. In addition, lavandin essential oil enhances the product’s effectiveness while providing a pleasant scent, a far cry from harsh chemical formulas.
For minor after-effects, the organic soothing roll-on takes over. Formulated withorganic essential oils of chamomile, lavandin, and geranium, it provides immediate natural relief. From the very first seconds, it soothes itching, reduces redness, and cools irritated skin. Its non-greasy texture and convenient size make it an ideal pocket-sized companion to slip into a travel bag or family first-aid kit.
This roll-on is perfectly suited for children ages 36 months and up. It has been dermatologically tested, ensuring safety and skin tolerance, even on sensitive skin. Its 100% organic composition guarantees a gentle, skin-friendly formula free of controversial ingredients, perfectly aligned with a natural health approach.
By combining the preventive lotion with the soothing post-bite treatment, Mousti K.O. Duo provides comprehensive care for exposure to bites. It is not just a comfort product, but a health prevention tool, essential for any traveler or resident of a humid area. Its ease of use and dual protective and restorative action make it a must-have for the summer first-aid kit.
This pack is particularly recommended for families, hikers, travelers to tropical destinations, and people living near ponds, wooded areas, or in hot regions. It offers a natural and effective alternative to conventional chemical products, while remaining highly effective and tailored to real-life daily needs.
To round out your protection, the Cinq-sur-Cinq Family Mosquito Repellent Spray 100 ml is also an excellent complementary option, especially for extended use at home or with the family.
Directions for Use
For the mosquito repellent lotion, shake the bottle well before each use. Spray directly onto exposed skin, then spread evenly. The lotion takes effect immediately after application. It is recommended to reapply after rubbing, excessive sweating, or depending on weather conditions. Each spray delivers approximately 0.2 ml of product. On average, 2 to 3 sprays are sufficient to cover an adult’s calf (equivalent to a dose of 0.2 mg/cm²). Do not exceed 3 applications per day for adults.
For the soothing roll-on, apply directly to the bite site using small circular motions. For children ages 3 to 12, limit use to twice a day. For children 12 and older, you may apply up to 3 times daily. This product works quickly to soothe, relieve, and refresh the affected area.

As a pharmacy specializing in natural remedies, we recommend enhancing your protection against insects with the following additional measures: wearing long, light-colored clothing, using treated mosquito nets, and diffusing essential oils such as lemon eucalyptus or rose geranium in your surroundings.
