Which frequency of sound can kill carpet beetles?

Carpet beetles can be adversely affected by ultrasonic sound frequencies, typically in the range of 20 kHz to 65 kHz. These high-frequency sounds can disrupt their behavior and potentially lead to their death. However, the effectiveness of this method can vary, and it may not be a guaranteed solution for eliminating infestations. For best results, it's advisable to combine ultrasonic treatments with other pest control methods.
