Which statement is true about ultrasonic pest control devices?

Ultrasonic pest control devices are designed to emit high-frequency sound waves that are inaudible to humans but intended to disrupt the behavior of pests like rodents and insects. The effectiveness of these devices has been widely debated and researched. While some studies suggest that ultrasonic frequencies may cause discomfort to certain pests, the overall consensus in the scientific community is that these devices do not produce significant, consistent results in pest control.

The statement that ultrasonic pest control devices do not work aligns with the findings of numerous studies, which show that while some pests may exhibit temporary avoidance of the sound, they often return once the device is turned off or they acclimate to the noise. This lack of reliable effectiveness makes the assertion that they are a dependable method of pest control inaccurate.

On the other hand, promoting the idea that these devices are effective for all pests overestimates their capability since not all pests respond similarly to ultrasonic frequencies. Additionally, the notion that they attract more insects conflicts with the intended function of these devices, as they are designed to deter pests rather than lure them in.

Considering these points, the assertion that ultrasonic pest control devices do not work is supported by current research and practical experiences in pest management.
