2025 New Smart Variable Frequency Ultrasonic Pest Repeller Rodent Repellent Insect Repellent

**🔊 Smart Variable Frequency Ultrasonic Pest Repeller | All-scenario Protection Expert**  
✔ **4-in-1 Multi-dimensional Repelling**: Exclusive variable frequency algorithm intelligently cycles through four modes for mosquitoes, rodents, insects, and flies, emitting 60 frequency bands per second of ultrasonic waves to interfere with the nervous system of pests, forcing them to flee.  
✔ **450㎡ Full Coverage**: High-intensity sound wave reflection technology ensures seamless protection, suitable for courtyards, warehouses, camping, and other scenarios. One device safeguards large apartments or villas.
✔ **0 Noise, 0 Radiation**: Operates at 25dB, an inaudible frequency for humans, making it safe for pregnant women, infants, and pets. No chemical pollution. Can be used outdoors with a power bank for continuous operation.  
✔ **365 days of automatic protection**: Built-in memory chip continues protection even after power failure, IP55 waterproof body withstands extreme weather, low power consumption design requires only 5 kWh of electricity per year.

**⚡ Four intelligent modes**
1️⃣ **Mosquito repellent mode**: 19-23kHz variable frequency pulses disrupt mosquitoes' ability to locate their prey  
2️⃣ **Rodent Repellent Mode**: 32-62kHz burst frequency range to stimulate rodents' auditory systems  
3️⃣ **Insect Defense**: 40-58kHz sweeping frequency technology to block insect reproduction signals  
4️⃣ **Fully Automatic Cruise**: Intelligent frequency switching with automatic power enhancement at night  

**🏆 Safety Certification**: Passed FCC/CE/RoHS testing, certified by Bayer Laboratories in Germany for repellency rates (92.7% for mosquitoes/88.3% for rodents)

**🎒 Essential Camping Technology**: About the size of a smartphone, it can still work in heavy rain, protecting tents, RVs, and picnic areas.  

• **60 frequency changes per second**: Far exceeds the 20 frequency changes per second response speed of traditional devices, preventing pests from developing resistance.
• **3D sound wave matrix**: Forms a立体防护网 through wall reflections, addressing the blind spots caused by the straight-line propagation of ordinary ultrasonic waves.
• Military-grade ABS shell resistant to extreme environments from -30°C to 80°C.
