ULTRASONIC DOG AND MOUSE REpellent

(Ultrasonic Dog, Mause Buster)

WE PRODUCED BETTER TODAY THAN YESTERDAY, NEW CIRCUITS WILL BE PUBLISHED SHORTLY
Many animals hear frequencies that humans cannot. Frequencies above 20 kHz cannot be heard by humans, but cats, dogs, mice and insects can hear them sensitively. The frequency most disturbing for dogs is 22-27 khz. The circuit is 22-27 khz for repelling dogs. frequency should be set.

Electronic dog Repellant (U.Dog Repellant )

The diagram was drawn by Graham Maynard to repel insects. We increase the power of the circuit, making the frequency 25 kHz. By setting e we will use it to repel dogs. The tweeter used in the circuit is 3.25 inch standard 85mm square Motorola Horn, Maplin part number WF09K or WF55K. +/-3dB to 28kHz.

Ultrasonic Dog Whistle(U.Dog Whistle)

The original of the dog whistle circuit was taken from Tomaz Lazar – Ljubljana, (Slovenia.). The circuit is 22khz for dogs. e should be set. Piezo should be of miniature type that can give 82 dB.

ULTRASONIC MOUSE REpellent

In the Middle Ages, 1/3 of the entire human population was lost to the plague. The main reason is that the mice harbor the fleas that carry the plague germ on them. In no war is there so much loss of life as caused by rats. This is an indication of how important it is to deal with the rats. The (commensal) rats and mice are the most numerous and successful mammals in the world today, apart from humans. They are intelligent animals, the only animal we unwillingly feed.

They would never have tasted this success without the help of people. What is a commensal rodent? The word commensal indicates that these animals live on people’s backs, invade their homes, eat their food, and damage their products and belongings; they can also infect people who do not benefit from this relationship.

Different methods are used in the fight against mice and rats. The most widely used of these are chemical methods. In chemical applications, poison baits are mostly used. If all methods fail, fumigation is used (poisonous gas). Only fumigation operators use this method. As long as the shyness of the mice is broken in poisonous bait applications, the fight will be successful. Sometimes shyness cannot be broken, especially in food processing and storage facilities; As long as you can’t break the rats’ eating habits, any poison bait will fail.

Ultrasonic mouse repeller can be used as a complement to other methods. It is also used in mouse-free environments, preventing mice from re-invading the area. Mice are particularly sensitive animals to sound. Even the simplest noise disturbs them. What we need to pay attention to here is to produce noise so that only mice can hear it without disturbing people. Rodent species 80khz. can hear sounds of frequencies up to Whereas the human ear is 20Hz.-20Khz. can hear high frequency sounds. Babies 20khz. what about can hear low frequencies.

This threshold falls with adulthood. It does not disturb people, but creates hellish noise for mice, allowing them to leave the environment. The circuits given here are 25-40khz. It is a circuit that gives sound over 120db in the frequency range. Attention Ultrasonic systems also affect some farm animals such as cats and dogs. The piezo tweeter you will use in the device should be of the type that can give the desired frequency.

What should we pay attention to when buying or designing a mouse repellent?

We must know the mice very well (to know the enemy well). He neither eats nor drinks, how he behaves. etc… the more documentaries we watch and mix up documents, the better our chances of success will be.

Electronic mouse and insect repellents are exaggeratedly touted as providing a definitive solution by the manufacturers. This is very wrong. So what do we do with deaf mice? Fighting with rats Fighting with ultrasonic sound is not a sure solution. It is only complementary. Will those who say there is a definitive solution be able to undertake to cover the damage that may occur when the devices do not work to those who are looking for a solution?

Since rats tend to mute the noise source (Ultrasonic repellent), they tend to gnaw on the electrical wires of the source, plugging the sound source with cloth or paper-like materials. Against the possibility of short circuit and fire of the electrical cables, the fuse must be connected to the most suitable place of the device.

It should be considered that other pets may also be disturbed by the sound in the area to be used. Cats and dogs can hear sound frequencies up to 27khz.

The device to be used should be able to produce the sound at the desired frequency and power. We see many devices with the name of Ultrasonic mouse repeller in the market. Piezo tweeter used. 20khz. It is one of those used in the music industry to get high-pitched sounds. The upper limit is 20khz. Twitter should never be used. It should be known that it will not work if used. If we use these devices, mice will laugh at us. The sound we need in the mouse fight is 25-35khz. is

The frequency must be constantly changing so that the mice do not become accustomed to the sound. Mice get used to constant sound and the same frequency, so there is no reaction to the sound.

There should be quiet periods at certain time intervals for the mice to move away from the environment. 15-25 sec. Mice should be given escape time by silencing the device between the first periods.

One of the faulty applications I have seen in some warehouses and factories is the use of more than necessary and out of sync devices. Devices must be synchronized, work simultaneously and frequency. Audio should be taken from a single source, distributed to other devices, and devices should be controlled from a single source.
