What is the claimed function of ultrasonic pest devices?

• A. They attract insects
• B. They repel insects
• C. They kill insects on contact
• D. They act as traps

Answer: (B)

Ultrasonic pest devices are marketed on the premise that they emit high-frequency sound waves that are intended to repel insects and other pests. The rationale is that these sound waves create an uncomfortable environment for pests, disrupting their communication and navigation abilities, ultimately driving them away from the area where the device is used. While empirical evidence supporting the effectiveness of ultrasonic devices is limited and often debated within the pest control community, the primary claim associated with these devices is indeed that they deter pests rather than attract, kill, or trap them. This focus on repelling reflects the general intention behind the design and promotion of ultrasonic pest devices.
