FAQ
Which of your A-Repeller devices do you recommend choosing?
Product choice depends on how big the rooms or spaces are, how many floors the building has, and the extent of the mouse problem in the building. We recommend starting with one product that has both A-Guard and ElectroPulse functions in the space where the problem is worst on the ground floor, and supplementing that with at least one A-Repeller with A-Guard in problem areas on the other floors, including the cellar and the attic. Choose a product that corresponds to the size of the rooms. Remember that the signal cannot penetrate solid materials such as walls, ceilings, floors, cupboards, etc. and that soft textiles reduce dispersion of the signal.
Why do some products also have electromagnetic pulses? Isn’t the ultrasonic signal enough?
The electromagnetic pulse, ElectroPulse, which supplements the ultrasonic effect, aims to deter rodents from using wiring as a rat-run. This combination of ultrasonic signals and electromagnetic pulses makes it uncomfortable for mice to remain or take up residence, and makes the repeller more effective.
Should I choose MR80 DG2 or MR130 DG4?
These two repellers both have Double Guard (A-Guard + ElectroPulse) and are suitable as a base unit. The powerful MR130 DG4 covers an open area of up to 130 m2, while MR80 DG2 covers up to 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.
Should I choose MR30 or MR50?
The powerful speaker on MR30 covers an open area of up to 30 m2, while MR50 covers up to 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.
Why do some of your A-Repellers also include the ElectroPulse/Double Guard feature?
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 signals and electromagnetic pulses makes it uncomfortable for mice and rats to remain or take up residence.
How do the electromagnetic pulses used by the repeller work?
Mice often use wiring in the walls to move around between different floors and rooms. They also gnaw on the cable sheath, 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 mice and rats and causes them to avoid the electric cables and thus the pulses.
Does the repeller create the pulsing magnetic field?
No, but it affects the magnetic field that forms around the cables connected to a power-consuming device, such as lights, refrigerators, electric heaters or other items connected to the mains supply in the building, that is switched on.
Does the repeller have to be plugged into a particular electric socket for the pulses to affect the magnetic field?
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.
Why are mice and rats affected by the electromagnetic pulses?
ElectroPulse makes the electromagnetic field vary in intensity. These variations in the electromagnetic field affect the learning ability and spatial perception of mice and rats, causing them to avoid the electric cables and thus the pulses.
Do the electromagnetic pulses disperse throughout the dwelling?
ElectroPulse 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.
How big a load should there be on the connected power-consuming device that is creating the magnetic field that the pulses are to affect?
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.
Does the repeller work in all spaces?
The repeller works in all indoor spaces. The ultrasonic signal is most effective if the device is 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. MR80 DG2, MR100 DG3 and 130 DG4 are suitable for spaces where there is a constant mains supply because of other electrical units, as this is needed for ElectroPulse to work. The ultrasonic signal, however, always works.
Can you use A-Repeller MR outdoors, under the building’s crawl space?
Our MR130 DG device is intended for this type of environment, as it is IP55 rated (water jet proof and dustproof). The other A-Repeller MR products are intended for use indoors in dry spaces. We do not recommend installing these repellers outdoors, as they contain sensitive electronics that cannot cope with a damp environment.
Can you use A-Repeller MR in an unheated storage room where the temperature will drop below zero in winter?
The repellers operate as intended in normal low winter temperatures. If it gets very cold and the temperature drops below -20 °C, this may affect functionality.
Can you use A-Repeller MR outdoors?
No. The ultrasonic signal requires the repeller to be situated in a room with walls, ceiling and floor in order to function as intended. If it is installed in a space without these surfaces, the acoustic pressure will be too low and the intended effect will not be achieved.
Are Silverline products safe to use in the home?
Silverline products are harmless to children, cats, dogs, birds and fish. They do not interfere with computers, TVs, etc. Rodents such as hamsters, guinea pigs and similar pets are also sensitive to the ultrasonic signal produced by our A-Repellers for mice, rats and spiders and should therefore not be kept in the same room as the device or neighbouring rooms. Some pets may react to KV 300, Ma50 and Ma200, but these are not harmful to them.
Can the human ear perceive the sound emitted by A-Repeller devices?
In normal cases, you can’t hear the ultrasonic signal emitted by the device, but in some cases humans can perceive high frequencies.
I have a mouse problem and want to start using a repeller/A-Repeller, what sort of things should I consider?
Mice and rats that have found a place where they can find food and warmth are sometimes unwilling to move on even if you install a repeller. Although the repeller is a source of irritation, their survival instinct when they know that there is a source of food nearby overcomes their desire to escape the noise. In such cases, established pests can for a short period be controlled and got rid of using traps. It is important to remove the traps once the pests have been caught, as the presence of bait may attract new pests. You should also clean carefully, as mice and rats leave scent trails (grease from their fur) as a guide and which they feel safe using. Without these trails, it is less likely that new pests will venture inside, especially if you have also installed an A-Repeller device.
What should you remember when positioning A-Repeller?
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.
Where should you position the A-Repeller device?
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 materials, such as walls, ceilings and floors, and that soft materials muffle sound.
How large an area does A-Repeller MR cover?
Our A-Repellers are equipped with powerful speakers that cover open areas of between 30 m2 and 130 m2. MR30 up to 30 m2 MR50 up to 50 m2 MR80 DG2 up to 80 m2 MR100 DG3 up to 100 m2 MR130 DG4 up to 130 m2.
How quickly does A-Repeller achieve the desired effect?
A change can normally be noticed immediately. In some cases it takes a bit longer. If there are already mice in the space, they will be more active when the repeller starts, before then being driven out. You can temporarily supplement with traps to root out the old infestation more quickly.
Can you use traditional mousetraps in kitchen cabinets as a supplementary measure?
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.
How do I get rid of mice from my attic?
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-Guard ultrasonic signal will not penetrate cardboard boxes or other solid objects. The same is true if mice have established themselves in the part of the attic where you have insulation. A-Repeller only disperses its ultrasonic signal over open areas. Mice could be inside the insulation, behind cardboard boxes and other things stored in the attic. In that case it is necessary to supplement with traditional traps.
Why are there mouse droppings in the cupboard under the sink even though we have an A-Repeller device in the kitchen?
This cupboard is often where people keep their food waste bin, which can attract mice. The instinct mice have to search for food is very strong and tends to be greater than their fear of external dangers. It is therefore 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. For example, store dry food in sealed containers, preferably in closed spaces. You can install an MR30 in the cupboard, ensuring that any gaps around pipe inlets are sealed up, using Silverline steel wool, for instance.
If the A-Repeller is located outside the cupboard, then the sound will be unable to penetrate inside.
How do you start A-Repeller?
Plug A-Repeller into a wall socket and it will start working immediately.
Where can A-Repeller MR be used?
It can be used in houses, storage areas, garages, summer cottages and other indoor spaces to repel mice and rats. A-Repellers with ElectroPulse are suitable for spaces where there is a constant mains supply because of other electrical units.
How will I know when A-Repeller is active?
The LED or LEDs light up or flash when the device is functioning.
This feature will vary depending on the type of A-Repeller you have. For devices that only use the A-Guard ultrasonic signal, the LED will be constantly lit, meaning the product is functioning correctly. For devices that use both the A-Guard ultrasonic signal and ElectroPulse, the green/blue LED will be constantly lit, while the red LED may be lit or may flash.
Do Silverline products affect other electrical equipment?
No, they do not affect other electrical equipment.
How long do the batteries in MR50 last?
The batteries in A-Repeller MR50 Battery last for approx. 5-6 months.
How does the ultrasonic signal disperse?
The advanced ultrasonic signal, A-Guard, 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.
Can A-Repeller products be harmful to animals?
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.
Does A-Repeller consume a lot of energy?
All Silverline products consume very little energy. MR30 - 1 W MR30 - 1 W MR50 - 0.5 W. MR80 DG2 - 1.8 W MR100 DG3 - 3.5 W MR130 DG4 - 4 W.
How does A-Repeller MR work?
All A-Repeller MR devices emit a varied and adapted A-Guard ultrasonic signal, which 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 20 and 130 m2, depending on the model. Repel 60, MR80 DG2, MR100 DG3 and MR130 DG4 also feature the ElectroPulse function. The electromagnetic pulse supplements the ultrasonic effect and aims to deter rodents from using wiring as a rat-run.
Why are mice and rats affected by A-Repeller MR?
Both mice and rats communicate by means of ultrasonic signals. The A-Guard adapted ultrasonic signal disrupts their natural means of communication and normal protective instincts. They perceive this as stressful and disturbing, which means they avoid taking up residence.
Does the ultrasonic signal stop mice and rats coming into the building?
If there is food accessible to them, then despite the repellers they can be attracted to, for example, kitchen cabinets where food waste bins are usually kept. Searching for food is a strong instinct. However, usually the ultrasonic signal prevents them from venturing further into the kitchen and drives them out again the same way they came in.
What pests are affected by A-Repeller?
A-Repeller MR is effective against rodents such as mice and rats. Pets such as rabbits, guinea pigs, hamsters and other rodents are also sensitive to ultrasonic sound and should not be kept in the same room as the device or neighbouring rooms.
How long do Silverline repellers normally last?
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 units for indoor use 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.
How long is the guarantee valid for?
The product guarantee is valid for 2 years and covers manufacturing defects. The guarantee is not valid in cases where the device has been exposed to excess voltage from the mains supply. The guarantee ceases to apply if damage has been caused to the unit or the purchaser has attempted to repair the unit.
What does it mean when it says that the power supply must have a constant load? Isn’t it enough for the device to just stay plugged in?
If all electrical equipment is switched off, there may be no effect. The repellers themselves do not draw more than 0.5-4 W depending on the model, so it will not create enough of a magnetic field in the power supply for the pulses to have an effect. The power supply should be loaded with at least 40 W to achieve the intended effect.
Are Silverline repellers sensitive to excess voltage from the mains supply?
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.
Why are there two modes for MR50 and MR80 DG2, “Summer” and “Winter”?
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 spiders, for example. These creatures are at their most annoying in summertime, so this setting has been designated “Summer”.
What is the difference between “Summer” and “Winter” modes in MR50 and MR80 DG2?
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.
Which mode should I select on MR50 or MR80 DG2 if I am bothered by the noise from the repeller?
If you select “Winter” mode, the repeller emits a sound at a higher frequency range, which the human ear is unable to hear.
Does A-Repeller also work in winter in a summer cottage if you don’t have anything plugged in that is drawing power?
If all electrical equipment is switched off, there may be no effect from the electromagnetic pulses. The repellers themselves do not draw more than 3.5-4 W depending on the model, 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.
