Rat Repellent Ultrasonic 【New Technology - Pest/Insect Repeller】 Equipped with PIR Sensor, 360° Omnidirectional Coverage, Effective Range 300㎡, Powerful, Silent, Electromagnetic Wave Free, Odorless & Non-Toxic, Energy-Saving Design, Safe for Children & Pets, Pest & Cockroach Repellent, Suitable for Ceilings/Rooms/Warehouses/Attics/Kitchens/Garages, Automatic/Sensing Mode, Japanese Instruction Manual Included (Green) No. 3397 【Industry-Leading, 2-Mode Ultrasonic Repellent】 The latest Grithope ultrasonic pest repeller features two ultrasonic repellent functions: "Sensing Mode" and "Automatic Mode." Sensing Mode activates immediately when the PIR sensor detects the movement of rats or cockroaches, efficiently repelling pests and insects. Automatic Mode constantly emits a stable frequency, providing long-lasting protection. Both modes strongly stimulate the hearing of pests and prevent them from getting used to (adapting to) specific frequencies, making them effective against many pests such as rats, cockroaches, mosquitoes, flies, and mites. It reliably protects indoor spaces in various environments, including homes, offices, warehouses, hotels, and restaurants. By using it continuously for a long period, you can maintain a comfortable and clean living space, making it an industry-leading ultrasonic pest repeller. 【360° Omnidirectional & Wide Area Coverage】 Equipped with a 360° omnidirectional speaker, it efficiently covers up to approximately 300㎡ (Kyoma: approx. 185 tatami mats / Edoma: approx. 194 tatami mats). The ultrasonic frequency has been optimized compared to conventional products, significantly improving the repellent effect. 【Energy-Saving, Safe & Silent Design】 Body size: Height 9.5cm x Width 7.5cm x Thickness 6.5cm, power consumption is only 1.5W (about half of the general commercial products), making it very energy-efficient. It is chemical-free, non-toxic, and radiation-free, making it safe for people, pets, and the environment. It is a silent type, so it won't disturb sleep, study, or work, and won't affect daily life. Since it does not have an insecticidal effect, there is no need to worry about disposing of dead insects or hygiene. While maintaining a quiet and comfortable space, it reliably prevents the unpleasant damage caused by rats and pests. This ultrasonic repeller is designed for safety and comfort, allowing it to be used with peace of mind in homes with children and the elderly. 【Easy Installation & Repellent Effect Realized in a Short Period】 Simply plug it into an outlet for immediate use; no battery replacement or charging is required, making it easy to install. You can feel the repellent effect within 1 to 4 weeks of starting use.
