Key Features Pure Physical Repellent Technology: Uses no chemical DEET or toxic substances, making it 100% safe for pregnant women, infants, the elderly, and even family pets. Advanced Sound Wave Frequency Range: Emits variable frequencies between 34Hz and 70KHz to effectively interfere with the sensory systems of various mosquito species.

Scientific Mimicry Principle: Cleverly simulates the frequencies of male mosquitoes and dragonflies, which pregnant biting female mosquitoes naturally evade to avoid secondary mating.
