6pcs Ultrasonic Pest Repellent, Indoor Use, Mosquito/Mouse/Cockroach/Rodent/Ant/Spider/Insect Killer

【Ultrasonic】This insect repellent repels all types of rodents and insects, including mice, spiders, cockroaches, flies, mosquitoes, bugs, and ants, using ultrasonic waves to make them uncomfortable. (It has no harmful effects on humans, children, or pets.) 【Easy to Use】The ultrasonic insect repellent is very simple to use. Just hold the repeller perpendicular to the ground, plug it into an outlet, and it will work automatically. When the blue indicator light is on, it means the product has started working. (We recommend installing the ultrasonic repellent 20-80 cm from the ground.) 【Remarkable Effect】It is normal to notice a significant increase in mouse and pest activity a few days before use. Don't worry! Because mice and insects that usually hide in their nests are attacked by ultrasonic waves, they will flee their original hiding places one after another. Most customers get satisfactory results in 3 to 4 weeks! 【Wide Coverage & Multiple Uses】The ultrasonic insect repellent has wide coverage and can reach 800 to 1200 square feet. It can be widely used in homes, warehouses, offices, gardens, hotels, etc., to protect you from pests throughout the day without worry.
