4 Pack Ultrasonic Insect and Rodent Repellent Electronic Pest Control Device Frequency Conversion Indoor Use Description

Ultrasonic Pest Repellent: This device uses ultrasonic waves and an electromagnetic chip to emit ultrasonic signals at a frequency of 22 to 65 kHz. These waves disrupt the nervous and auditory systems of pests, helping protect your home from insects, mice, rodents, mosquitoes, and other unwanted intruders.

Wide Coverage: The ultrasonic waves cover an area of 75 to 110 m². Because they do not pass through walls or solid objects, it is recommended to place one unit in each room. For larger rooms, such as storage areas, two or more repellents may be needed.

High Efficiency: This pest repellent works continuously 24 hours a day, 7 days a week. For best results, it should be installed vertically at a height of 80 to 120 cm from the floor. With continuous use, the maximum effect is typically reached after 3 to 4 weeks.

Eco-Friendly and Easy to Use: Simply plug the unit into a standard wall socket to start it. No batteries are required, helping you save on replacement costs. In addition, it operates quietly and contains no chemicals, is non-toxic, and has no odor.

Multiple Applications: This pest control repellent is widely used to help drive away rats, insects, bed bugs, fleas, rodents, cockroaches, mosquitoes, ants, spiders, fruit flies, and other insects and rodents inside your home. The ultrasonic waves help encourage them to leave quickly.
