Bionic acoustic wave technology, efficient repelling Interference with bat sonar system: By emitting ultrasonic waves of specific frequency, it interferes with the bat's sonar positioning system, making it disorientated and unwilling to approach. Dual action: Combined with natural plant odour blending, it further enhances the repelling effect and makes bats stay away voluntarily. Safe and environmentally friendly, harmless and pollution-free No harm to bats: adopting physical repelling method, it will not cause harm to bats, which is in line with the principle of ecological protection. Harmless to human body: the ultrasonic frequency is beyond the hearing range of the human ear, and will not cause any discomfort or impact on the human body. Easy to operate, convenient to use Plug and play: just plug in the power supply and start working, no need for complicated settings. Compact and portable: small size, does not take up space, can be placed in the corner of the bat often frequented or the entrance. Multi-scenario application, remarkable effect Family house: applicable to the eaves of your home, windows and other areas frequented by bats, giving you a quiet, undisturbed living environment. Commercial places: such as warehouses, factories, etc., can also effectively repel bats and protect property safety.
