DEET vs Natural Mosquito Repellents: What Science Says About Protection and Safety
Mosquitoes kill more humans than any other animal, transmitting diseases like malaria, dengue, and Zika to billions worldwide. This analysis examines the effectiveness and safety of various mosquito repellents. DEET remains the gold standard, providing several hours of protection with an excellent safety profile despite decades of use. Picaridin performs similarly to DEET without the plastic-melting properties or unpleasant odor. Most natural alternatives like citronella and essential oils provide minimal protection lasting only minutes. However, lemon eucalyptus oil stands out as the only plant-based repellent recommended by the CDC, offering 4-12 hours of protection comparable to DEET. Electronic repellent devices proved completely ineffective in studies.
