Ultrasonic Mouse and Rat Repellent, 4-Pack Ultrasonic Mouse and Rodent Repellent, Indoor Ultrasonic Mosquito Repellent for Mosquitoes, Mice, Rats, Rodents, Cockroaches, and Spiders

【Effective Ultrasonic Mouse Repellent】This ultrasonic mouse and rat repellent emits ultrasonic waves to disorient and disrupt pests, preventing them from feeding or nesting in your home. Say goodbye to mice, rodents, mosquitoes, rats, spiders, fleas, insects, flies, cockroaches, and ants. 【Safe for Humans and Pets】Our ultrasonic mosquito repellent uses ultrasonic sounds inaudible to humans and pets. Free of poison, odor, and chemicals, it is safe and harmless for children, pregnant women, and your pets. 【Large Coverage Area】Each ultrasonic mouse and rat repellent effectively covers up to 150 m² (1600 sq ft). Since ultrasound does not penetrate walls and solid objects, it is recommended to use one unit per room to ensure that every corner of your home is protected from pests. [Visible Results in Weeks] It is normal to see a temporary increase in pests at first, as they flee their hiding places. Expect significant results within 2 to 4 weeks, depending on the severity of the mouse and insect infestation. [Easy Installation] Simply plug the ultrasonic mouse repellent into an electrical outlet, and it will start working immediately. For optimal effectiveness, install it at a height of 10-30 inches (25.4-76.2 cm) for crawling pests and 30-50 inches (76.2-127 cm) for flying insects.
