I. Introduction: Summer Outdoor Activities and Mosquito Problems

As summer arrives and temperatures rise, people increasingly participate in various outdoor activities such as family gatherings, wilderness adventures, and beach vacations. However, the proliferation and activity of mosquitoes can spoil these enjoyable experiences. Mosquitoes not only cause skin irritation but may also transmit diseases like dengue fever, malaria, Lyme disease, and West Nile virus. Individuals who sweat easily, have type O blood, or stronger body odors are particularly vulnerable to mosquito bites. Therefore, establishing comprehensive, scientifically sound protective measures is essential to maintain health while enjoying outdoor activities.

II. Effective Mosquito Repellent Ingredients and Usage Principles

To effectively repel mosquitoes, understanding the different active ingredients and their safe usage principles is crucial. Below are several widely recognized repellent ingredients and their characteristics:

  1. DEET (N,N-Diethyl-meta-toluamide) : As one of the earliest extensively studied repellents, concentrations of 25%-30% typically provide 6–10 hours of protection. While higher concentrations (e.g., 98%) offer longer protection, they may damage fabrics and plastics and can cause skin irritation in some individuals.
  2. Picaridin (Icaridin) : With a lighter scent and safer profile for plastics and fabrics, it offers protection duration similar to DEET and is particularly suitable for people with sensitive skin and children.
  3. IR3535 : Mild and safe, often used in children's formulations. While its protection duration is slightly shorter than DEET and Picaridin, it works well in low to moderate mosquito environments.
  4. Oil of Lemon Eucalyptus (OLE, PMD) : A natural ingredient providing 4–6 hours of protection. Not recommended for children under 3 years old; suitable for short family outings or low mosquito activity areas.
  5. Permethrin : Designed for treating clothing and gear surfaces—not for direct skin application. Treated items retain protection through multiple washes.

III. Types of Mosquito Repellent Products and Market Recommendations
