Ultrasonic Pest Repeller, 2 Pack [Upgraded Version] Plug-in Ultrasonic Insect Repellent

【2025 Latest Model - Enhanced Pest Repeller】Built with an advanced smart chip, it emits multiple frequencies including resonant and reflective ultrasonic waves, switching between them. This stimulates the nervous systems of various pests such as cockroaches, mosquitoes, ants, spiders, mites, and mice, making them uncomfortable and driving them out of your home. *This product is intended for repelling pests and does not have a direct insecticidal effect.
【3 Modes - Covers Up to 230 Tatami Mats】Simply plug it in to operate; no batteries required. It covers approximately 120-370㎡ with ultrasonic waves ranging from 1 to 90kHz. Changes in insect activity can be observed within one week of use, repelling effects appear in the second to third week, and pests will be significantly reduced within four weeks. Ideal for homes, restaurants, warehouses, garages, and more.
【Repelling Mechanism】The sound waves in each mode are superimposed signals of multiple ultrasonic frequencies. Type 1 (for flying insects like mosquitoes): 150-500Hz (mimics the wingbeats of predators like dragonflies) + 40kHz-90kHz (induces escape response in houseflies). Type 2 (for insects like cockroaches): 20kHz-50kHz (disorients cockroaches by simulating predator detection) + 500Hz-900Hz (mimics termite nest vibrations to encourage return, leading to repeated hunting failures for spiders and causing them to leave voluntarily). Type 3 (for all types of mice): Continuous rising frequencies from 15Hz-50kHz (covers their entire hearing range) to induce anxiety and stress responses, causing immediate departure. 【Adaptation Prevention System】The 3 modes automatically switch at high speed every 0.8 seconds. This covers all pest species while also preventing adaptation by applying new stress responses immediately after a temporary sensory recovery during the switch. (*Physical repelling technology that induces pest escape behavior, respecting the ecosystem without killing them.)
【Silent, Odorless, Non-Toxic】Made with ABS flame-retardant material, it uses no chemicals, sprays, or radiation, making it non-toxic, odorless, and environmentally friendly. It affects pest behavior through physical means and is harmless to humans and pets.
