WIRELESS - ULTRASONIC PEST REPELLER LS-925M Repels MARTENS, MICE, RATS, COCKROACHES and other pests, for cars or other places without a permanent power source. A newer and more powerful version of the LS-925 model, increased repeller signal strength and two batteries that improve the device's operating time. The use of ultrasonic waves to repel pests is known in the field of rat extermination and pest and insect control. The appropriate intensity and frequency of the ultrasonic wave affects the auditory and nervous systems of most common insects and pests. These creatures want to avoid the location of the repeller, thus abandoning their nests. The repeller also prevents the emergence of new individuals, effectively and permanently protecting your home, office, or car. DEVICE FEATURES: The repeller emits direct sound waves with a variable frequency in the range of 25,000 Hz to 26,000 Hz with a duration of 0.3 seconds every 4 seconds. The variable frequency prevents pests from becoming accustomed to the sound. For example, a clock ticking at a frequency of 1 second becomes insignificant to humans after a while and we begin to treat it as background noise. In the case of a repellent, the wave height is variable, and a short signal (0.3 second) with 4-second pauses causes a strong attack on the pests' nervous systems, making these sounds unacceptable to them, and thus causing them to leave the location where the device is installed. The LS-925M repellent is an improved model powered by two 9V batteries , allowing the device to operate for 6 to even 8 months in 24-hour mode. The effective range of the for repelling martens, mice, and rats is approximately 140 to 180 square meters in an open area and approximately 80 square meters for smaller insects such as fleas and ticks. An undoubted advantage of the device is that it is battery-powered, so it can be installed in hard-to-reach places, without sockets and power sources, in extreme parts of buildings, in closets, cars and outbuildings. TECHNICAL SPECIFICATIONS: Dimensions: diameter Ø108 mm, height: 24 mm Frequency range: 25,000 Hz to 26,000 Hz Effective operating range : up to 760 square meters of open space. Power supply: 2 x 9V battery Sound pressure output: 130 dB (average) BOTTOM PART OF THE DEVICE: The repeller has a mounting hole, so you can easily mount it on a wall or ceiling. It has CE and ROHS certificates, made of ABS plastic. The device's effective range is greatest in an open space. If the room is full of obstacles (walls, ceilings, floors, other partitions), it is recommended to install a separate device in each room. In the car, place the device so that it is not pressed down, obscured by rugs, or other objects, so that the sound can spread freely. Soft materials such as polystyrene, wool, sponge, carpet, blankets, mats, etc. absorb sound waves, effectively reducing the device's effectiveness. Hard surfaces, on the other hand, positively affect the device's effectiveness; sound bounces off the surface, filling the room with sound – as shown in the illustrations.
