Mosquito Repellent: High Concentration Doesn't Mean Better Protection

As the summer heat intensifies on Madeira Island, the demand for mosquito repellents rises among both residents and tourists. However, a recent study by DECO PROteste, a consumer protection organization, has uncovered surprising findings about these products' effectiveness.

Contrary to common belief, a higher concentration of active ingredients in mosquito repellents does not necessarily guarantee better protection. The study evaluated dozens of products and concluded that the effectiveness of repellents is influenced more by the type of active ingredient, how the product is applied, and the conditions of exposure.

Mosquito repellents are crucial in areas like Madeira, where the climate supports high mosquito activity during summer months. They work by masking the human scent that attracts mosquitoes, rather than killing them.

DECO PROteste emphasizes that consumers should focus on the active ingredient listed in the product rather than just its concentration. Popular active ingredients include DEET, picaridin, and oil of lemon eucalyptus, each with different properties and effectiveness.

• Apply repellents evenly on exposed skin.
• Reapply as directed, especially after swimming or sweating.
• Choose products suited for specific activities and environments.

Understanding the right application methods and the conditions in which repellents are used can significantly enhance their effectiveness. For instance, applying too much of a high-concentration product can be both ineffective and potentially irritating to the skin.

The DECO PROteste study serves as a reminder to make informed choices when selecting mosquito repellents, focusing on the right active ingredients and proper usage rather than just high concentrations. This insight is particularly valuable for those visiting Madeira, ensuring their stay remains comfortable and mosquito-free.
