1. Dual ultrasonic speakers can stimulate two powerful ultrasonic sound streams with different frequencies, and multiple working modes can be selected. Bats cannot adapt to multiple frequencies of ultrasound, which interferes with their auditory and nervous systems. Make it unable to survive here and drive it away.
2. During the effective driving period, there are significant individual differences and a variety of bats, requiring continuous use of the bat exclusion device for 20 days. Only then can it produce better results.
3. Safe and harmless, people and pets cannot hear the sound of ultrasound, so it is harmless to people and pets.
4. Easy to install, plug and work ，and easy to use.
5. The combination of multiple bat exclusion devices can achieve a comprehensive driving effect.
