FAQ

If the mice have already established themselves in the part of the loft where you have insulation, it is very difficult to get rid of them, since the A-Frequency™ ultrasonic signal will not penetrate insulation. The solution may be to put down one or more Mice & Rat Free™ devices to disperse their A-Frequency™ ultrasonic signals over the open areas, and to also use traditional traps as a supplement for getting at them.

Mice in the attic can generally be hard to get rid of. Most of us have loads of stuff in the attic, such as cardboard boxes and clothes. The A-Frequency™ ultrasonic signal will not penetrate cardboard boxes or other solid objects. Mice & Rat Free™ only disperses its ultrasonic signal over open areas. Mice could be behind cardboard boxes and other things stored in the attic. In that case it is necessary to supplement with traditional traps.

It is important to ensure that you never give mice a chance to get at food. No scraps of food or pet food should be left where they can access them. Allowing them to get at food makes it harder to drive them out of the house.

The instinct mice have to search for food is very strong. It can be greater than their fear of external dangers. It is important to always make sure no pet food or food scraps are left accessible, since they can attract mice and rats into the house.

You should not store dry fodder, pet food, bird food, etc. open in any space where you suspect mice can get in. Attractive food means they can get in to eat it and then go away again.

This cupboard is often where people keep their compost bins, which can attract mice. You can put a Mice & Rat Free 25™ inside the cupboard. You can get the best effect if you ensure the ultrasonic signal can flow unimpeded. The sonic signal cannot pass through solid materials and its strength is reduced by soft materials. Unfortunately it may be necessary to use traditional mousetraps when you begin your eradication campaign.
We recommend that you avoid leaving food that mice find attractive in open containers, and that you seal around all pipes and other spaces where mice can get in.

At the start of an eradication campaign or in spaces the ultrasonic signal cannot reach, it may be appropriate to use traditional traps as a supplement. You must remember, however, that baited traps will attract mice.

These setting options change the frequency range. In “Summer” mode the frequency runs on a random scale in a lower frequency range than in “Winter” mode.

In “Winter” mode the frequency range is adapted to stress and scare away all rodents. In “Summer” mode the frequency range is adapted to also reduce the prevalence of creepy crawlies such as small spiders, beetles, etc. These small creatures are at their most annoying in summertime, so this setting has been designated “Summer”.

The pulses can be adjusted using the button on the side. Switching between mode I and II every four weeks or so is recommended, to avoid the rodents becoming accustomed to the pulsing. The red LED flashes in mode II and shows a fixed light in mode I to indicate that the pulse function is operating.

The pulse rate can be adjusted using the button on the side. Switching between SLOW and QUICK mode every four weeks or so is recommended, to avoid the rodents becoming accustomed to the pulsing.

Silverline products that are intended for indoor use should not be exposed to direct sunlight.

They contain electronics that are as sensitive to flash-over as computers, TVs, etc. It is possible to protect them from flash-over by installing a surge protector between the repeller and the wall socket. The guarantee ceases to apply if the repeller has been exposed to excess voltage from the mains supply.

Our products are made to be used for a long time without any problem. They are made up of electronic components that in themselves do not have any estimated useful life, but there are some things you should remember so as not to shorten their useful life. Use and store the unit indoors, in a dry location only. Do not expose units intended for indoor use to prolonged direct sunlight. Do not expose the unit to excess voltage from the mains supply.

No, they do not affect other electrical equipment.

Mice that have already established themselves in an environment they perceive as safe will to start with investigate what is happening and will become unsettled. After a while they will disappear once their environment has turned into an unsafe place for them.

Yes, it does. However, it will take longer to repel them, because they have established themselves in an environment they feel is safe. First they become unsettled and run around to investigate what is happening. But after a while they will leave that space.

If all electrical equipment is switched off, there may be no effect from the electromagnetic pulses. The repellers themselves do not draw more than 1.8 or 3.5 W respectively, so it will not create enough of a magnetic field for the pulses to have an effect. The ultrasonic signal will of course still have a repellent effect.

If all electrical equipment is switched off, there may be no effect. The repellers themselves do not draw more than 1.8 or 3.5 W respectively, so it will not create enough of a magnetic field in the power supply for the pulses to have an effect.

A magnetic field is automatically created around any electric cables connected to a power source. The load should be at least 40 W to generate a sufficiently large magnetic field. In certain electrical installations where lead-sheathed cables have been used, the magnetic field will be weaker.

When you plug the repeller into a wall socket, that wall socket is then electrically linked to the rest of the building’s mains supply. Therefore the repeller affects the mains supply no matter which socket it is plugged into. However, the effect reduces with increased distance between the socket where the repeller is plugged in and other parts of the mains supply in the building.

The electromagnetic pulse, ElectroPulse™, which supplements the ultrasonic effect, aims to deter rodents from using wiring as a rat-run. This combination of ultrasonic signal and electromagnetic pulses makes it uncomfortable for mice to remain or take up residence, and makes the repeller more effective.

It is important to remember that the ultrasonic signal does not penetrate solid objects such as furniture, cupboard doors, walls and ceilings. Soft textiles such as upholstery and curtains reduce the signal dispersion and hard surfaces block it. Therefore you should plug the repeller into a wall socket that is as unimpeded as possible.

Plug the repeller into a low wall socket that is as unimpeded as possible, in any room where you suspect there are mice. Remember that high-frequency sound cannot penetrate solid material, such as walls, ceilings, floors, etc. And that soft material muffles sound.

The repeller works in all indoor spaces. The ultrasonic signal is most effective if the device is positioned in as unimpeded a position as possible so the dispersion of the ultrasonic signal is not restricted by solid objects such as furniture, doors, etc.

This advanced ultrasonic signal, A-Frequency™, disperses in open spaces. The physical characteristics of the ultrasonic signal mean that the signal cannot pass through solid objects such as furniture, cupboards, walls and ceilings. Soft textiles such as upholstery and curtains, for their part, absorb the signal. This means that the repeller should be positioned where the ultrasonic signal can disperse in as unimpeded a way as possible.

If all electrical equipment is switched off, there may be no effect from the electromagnetic pulses. The repellers themselves do not draw more than 1.8 or 3.5 W respectively, so it will not create enough of a magnetic field for the pulses to have an effect.

Therefore the repeller affects the mains supply no matter which socket it is plugged into. However, the effect reduces with increased distance between the socket where the repeller is plugged in and other parts of the mains supply in the building.

The pulses will spread to live cables connected to the same distribution box. If a dwelling has two distribution boxes with separate feeds, two devices should be used for optimum protection.

No, but it affects the magnetic field that forms around the cables connected to a power-consuming device, such as lights, refrigerator, electrical elements or other things connected to the mains supply in the building that are switched on.

ElectroPulse™ makes the electromagnetic field vary in intensity. These variations in the electromagnetic field affect the learning ability and spatial perception of the mice, making them leave the electric cables and thus the pulses.

Mice often use wiring in the walls to move around between different floors and rooms. They also gnaw at the wiring, which can cause short-circuits, resulting in a risk of fire. ElectroPulse™ means that the electromagnetic field varies in intensity in the live cables in the building’s mains supply. This affects the mice and makes them leave the cables and thus the pulses.

The electromagnetic pulse, ElectroPulse™, which supplements the ultrasonic effect, aims to deter rodents from using wiring as a rat-run.

This combination of ultrasonic signal and electromagnetic pulses makes it uncomfortable for mice to remain or take up residence.

Mice & Rat Free 80/200™ and Mice & Rat Free 100/400™.

All our Mice & Rat Free™ devices change frequency automatically.

If there is food accessible to them, then despite the repellers they can be attracted into e.g. kitchen cabinets where the compost bin is usually kept. Searching for food is a strong instinct. However, usually the ultrasonic signal prevents them from going further into the kitchen and drives them out again the same way they came in.

In normal cases, you can’t hear the ultrasonic signal emitted by the device, but in some cases humans can perceive high frequencies.

No, the repeller does not harm animals. However, the ultrasonic signal emitted by the repeller makes mice and rats feel unsafe in the space where the repeller has been placed. So they choose somewhere else to take up residence.

The advanced A-Frequency™ ultrasonic signal disturbs and distracts them within an open area of between 25 m2 and 100 m2, depending on the model, which means that they avoid taking up residence in that space.

The ultrasonic signal scares them away and stops them establishing themselves in that space and starting to gnaw and destroy things. If there are already mice in the space, they will be more active when the repeller starts, before then being driven out.

Both mice and rats communicate by means of ultrasonic signals. The A-Frequency™ adapted ultrasonic signal emitted by Mice & Rat Free™ disrupts their natural means of communication and normal protective instincts. They experience this as stressful and disturbing, which means they avoid taking up residence.

The electromagnetic pulse, ElectroPulse™, which supplements the ultrasonic effect, aims to deter rodents from using wiring as a rat-run. This combination of ultrasonic signal and electromagnetic pulses makes it uncomfortable for mice to remain or take up residence, and makes the repeller more effective.

The varying and adapted A-Frequency™ ultrasonic signal is perceived as stressful and disturbing by rodents, which means that they avoid taking up residence in that space. The ultrasonic signal creates an unbearable environment for mice and rats within an open area of between 25 m2 and 100 m2, depending on the model.

All Silverline Mice & Rat Free™ devices emit a varied and adapted A-Frequency™ ultrasonic signal.

The powerful speaker, AH-HZ Speaker™, in Mice & Rat Free 25™ covers an open space of approximately 25 m2 and Mice & Rat Free 50™ covers approximately 50 m2.
Choose the product that corresponds to the size of the room. Remember that the signal cannot penetrate solid materials such as walls, ceilings, floors, cupboards, etc. and that soft textiles reduce dispersion of the signal.

These two repellers have both A-Frequency™ and ElectroPulse™ and are suitable for selection as a base unit. The powerful speaker, AH-HZ Speaker™, in Mice & Rat Free 100/400™ covers an open space of approximately 100 m2 and Mice & Rat Free 80/200™ covers approximately 80 m2.
Choose the product that corresponds to the size of the room. Remember that the signal cannot penetrate solid materials such as walls, ceilings, floors, cupboards, etc. and that soft textiles reduce dispersion of the signal.

Product choice depends on how big the rooms or spaces are, how many floors the building has, and how big the mice problem is in the building.
We recommend starting with one base unit that has both A-Frequency™ and ElectroPulse™ functions in the largest space on the ground floor, and supplementing that with at least one Mice & Rat Free with A-Frequency™ on other floors, including the cellar and the attic.

Mice that have already established themselves in an environment they perceive as safe will to start with investigate what is happening and will become unsettled. After a while they will disappear once their environment has turned into an unsafe place for them.

Yes, it does. However, it will take longer to repel them, because they have established themselves in an environment they feel is safe. First they become unsettled and run around to investigate what is happening. But after a while they will leave that space.

This advanced ultrasonic signal, A-Frequency™, disperses in open spaces. The physical characteristics of the ultrasonic signal mean that the signal cannot pass through solid objects such as furniture, cupboards, walls and ceilings. Soft textiles such as upholstery and curtains, for their part, absorb the signal. This means that the repeller should be positioned where the ultrasonic signal can disperse in as unimpeded a way as possible.

If the mice have already established themselves in the part of the loft where you have insulation, it is very difficult to get rid of them, since the A-Guard ultrasonic signal will not penetrate insulation. The solution may be to put down one or more Mice & Rat Free™ devices to disperse their A-Guard ultrasonic signals over the open areas, and to also use traditional traps as a supplement for getting at them.

These setting options change the frequency range. In “Summer” mode the frequency runs on a random scale in a lower frequency range than in “Winter” mode.

The electromagnetic pulse, ElectroPulse™, which supplements the ultrasonic effect, aims to deter rodents from using wiring as a rat-run. Suitable for spaces where there is a constant mains supply because of other electrical units. This combination of ultrasonic signal and electromagnetic pulses makes it uncomfortable for mice to remain or take up residence.

Mice & Rat Free 80/200™ and Mice & Rat Free 100/400™.

The repeller works in all indoor spaces. The ultrasonic signal is most effective if the device is positioned in as unimpeded a position as possible so the dispersion of the ultrasonic signal is not restricted by solid objects such as furniture, doors, etc.
