The best Isotronic mouse repellents, compared.
Top pick: Isotronic 70632-B two-unit title – Highest card score in this set, 3.7 from 3,990 shared ratings, at about £39.95. The three-unit 70632 title ties that star line at about £49.95. On both, the pieces field says 1, and the power row says AC while the bullets say battery. Not a clearance. Best value: Isotronic 70624 one unit – About £26.95, the lowest price here. Title and pieces field both say one unit, and the power row agrees with the battery bullets. 3.6 from 3,198 shared ratings. Updated October 2026.
An Isotronic mouse repellent is a battery ultrasonic unit sold to disturb mice or rats in one closed room, loft, cellar, garage or shed. In the UK you usually choose one because that space has no socket. The sound does not pass walls or furniture, so a house is one room at a time. A claimed floor area is not a measured volume. Check the power row against the bullets, which usually say battery and no mains lead. A title that says two or three units can sit next to a pieces field of one, so the box count is confirmed only when those fields match. Reviews on a parent listing are not a separate trial for every pack. The tone is not silent. Instructions for this class state a band around 12–24 kHz, with a short burst and a longer pause. People, cats and dogs can hear part of that band. Inaudible is seller language. Seal the gaps, then check droppings. How to read a listing that disagrees with itself is in the [Isotronic mouse repellent buying guide](/hub/pest-control/isotronic-mouse-repellent/sub/isotronic-mouse-repellent-buying-guide).

Personal buying guide
Question 1 of 2
Where will it sit?
The two-unit 70632-B title is £39.95 with model 70632-B, 18 x 9 x 6 cm and 96 g. The style name says 2 Set and the pieces field says 1, so the pack count is not confirmed. Power says AC while the bullets say battery and no mains lead. The star line is 3.7 from 3,990, and the same review titles are on the three-unit 70632 title, so this is not a separate 3,990-person trial. Saved reviews include lofts that went quiet, a rat that ignored units, water behind a foam O-ring, and covers that needed a screwdriver. Bullets still call the sound inaudible and limited to 40 m² without passing walls. The loft, other-pest and weatherproof questions are unanswered.
Pros
Cons
Best for: You already know this parent line and only need the two-unit title as a price point, after checking the pieces field.
Less suitable: You need the box count to match the title, or a power row that says battery.
Specifications
Common questions
Will the box contain two units?
The title and style name say 2 Set. The number of pieces is 1. The captured listing does not show a packing list that confirms two housings.
Is it a plug-in?
The power row says AC. The bullets say battery operation and no power connection. Do not buy it as a mains plug-in on this listing.
What do the saved reviews repeat?
In the first 50, buyers mention stiff covers, a foam O-ring that let water in, a tone people and a cat could hear, and lofts that either went quiet or did not. The same titles appear on the three-unit 70632 title.
This is the dearest row in the capture, £49.95, titled as three 70632 units. Model and part number are 70632, size 18 x 9 x 6 cm, 96 g. The pieces field says 1. Power says AC and the bullets say battery, the same conflict as the two-unit 70632-B title. Stars are 3.7 from 3,990 with the same review titles, so the higher price does not buy a separate evidence base. Those reviews include quiet lofts, a rat that was not bothered, water behind a foam O-ring, and screws too small to open. The children question on the page is unanswered.
Pros
Cons
Best for: You only consider it if the live listing shows three housings and you already accept the shared review line.
Less suitable: You want one confirmed unit, a battery power row, or a lower price for the same parent reviews.
Specifications
Common questions
Does the three-unit title match the pieces field?
No. The style name is 3 Set and the title says 3 units. The number of pieces is 1. The captured price is about £49.95, the highest in this set.
Is the 3,990-rating line unique?
No. The same star line and the same saved review titles appear on the two-unit 70632-B title.
Does the listing answer the children question?
It asks whether the unit is safe around children and does not answer. Bullets say the frequencies are inaudible. Reviews in the shared sample say people can hear the tone.
This is the £26.95 one-unit 70624. The title, style name and pieces field all say one unit, and both the power row and the bullets say battery, so you are not paying a multi-pack price for a conflicting pieces field. The star line is 3.6 from 3,198 ratings, and the same review titles appear on the grey two-unit title and the three-unit title in this set, so that count is not three separate trials. Saved reviews include a loft with no socket, a 30-second tone people can hear, a cat that stayed downstairs, and screws too tight to open. Bullets still say the sound is inaudible and that it does not pass walls.
Pros
Cons
Best for: You want one battery 70624 for a single closed room and a pieces field that matches the title.
Less suitable: You need a confirmed multi-unit box, a silent unit, or a listing whose ratings are not shared with other packs.
Specifications
Common questions
Does the pieces field match the one-unit title?
Yes. The style name is 1 and the number of pieces is 1, at about £26.95.
Does the listing say battery or mains?
The power source is battery, and the bullets say no mains connection. The electric field is Yes.
What do the saved reviews say about noise and pets?
In the first 50 reviews, a buyer heard a high-pitched pulse about every 30 seconds. Another said a cat avoided upstairs while a loft unit ran. The same review titles sit on two other 70624 pack listings.
This grey row is titled as two units at £41.01. The part number is 70624 and the model field is 14671, which the capture does not explain. Pieces are 1, so the two-unit title is not confirmed. The electric field says No even though the power row says battery. Stars are 3.6 from 3,198, with the same review titles as the £26.95 one-unit and the £45.28 three-unit title. Those reviews include an audible 30-second pulse, a cat that avoided upstairs, rain that brought activity back, and screws too tight to open. Colour is the clear difference: grey, not black.
Pros
Cons
Best for: You specifically want the grey 70624-part listing and will check how many housings arrive.
Less suitable: You want one confirmed unit, a matching model and part number, or an electric field that says Yes.
Specifications
Common questions
Which model number is on the listing?
The model number field says 14671. The manufacturer part number says 70624. Dimensions match the other 70624 rows: 14 x 8 x 3 cm and 80 g.
Does the two-unit title match the pieces field?
No. The style name is 2 and the title says 2 units. The number of pieces is 1.
Why does the electric field say No?
That row says No, while the power source is battery and the bullets describe an ultrasonic repeller. The 3,198 review titles match the black one-unit and three-unit 70624 rows.
The black three-unit 70624 title is £45.28, with model and part number both 70624 and the same 14 x 8 x 3 cm, 80 g body as the £26.95 one-unit. The style name is 3 and the pieces field is 1, so you are not shown three housings in the spec table. Power is battery on both the row and the bullets. The 3.6 from 3,198 is the shared 70624 line, including a review of three units whose screws would not open and the loft cat that could hear the tone. You pay more than the one-unit row for a title pack the pieces field does not confirm.
Pros
Cons
Best for: You only consider it after the live pieces field shows three housings.
Less suitable: You want one confirmed unit at the lower 70624 price.
Specifications
Common questions
Does the three-unit title match the pieces field?
No. The style name is 3 and the title says 3 units. The number of pieces is 1. The captured price is about £45.28.
Are the reviews unique to this pack?
No. The 3.6 from 3,198 line and the saved review titles match the £26.95 one-unit and the grey two-unit title.
What battery problem shows up in that shared sample?
One buyer could not open the battery screws on all three units in the order. Another heard a pulse about every 30 seconds.
This is the one-unit 70632-B title at £32.95. There is no model-number field, only part number 70632-B, and the pieces field matches the one-unit title. It is the 70632-family row with its own star line, 3.3 from 235, rather than the shared 3,990. The conflict is power: the spec says AC, the bullets say battery, and reviews say 6 AAA or 4 AAA, sometimes missing, sometimes described as a rechargeable that was not. Size is 18 x 9 x 6 cm and 158 g. Saved reviews also include a quiet winter aimed at a cupboard gap, rats that sat beside outdoor units, and a tone people could hear.
Pros
Cons
Best for: You want one 70632-B housing and a review count that belongs to this listing.
Less suitable: You need the listing power row to say battery, or you are choosing it as a plug-in.
Specifications
Common questions
Is this the same review set as the 3,990-rating 70632 rows?
No. This listing line is 3.3 from 235, and the first 50 review titles differ from the two-unit and three-unit 70632 titles.
Why do power and batteries disagree?
The spec row says power source AC. The bullets say battery and no mains connection. Reviews mention 6 AAA or 4 AAA, which is not in the spec table.
What went wrong in the saved reviews?
Buyers report rats walking in front of the unit, a stiff six-screw cover, missing batteries, and a unit sold as rechargeable that took AAA cells and had no charger.
The 70500 three-pack is £38.66, and the title, unit count and pieces field all say three. The title adds LED and volume control. Bullets claim 30 m² and battery use. Stars are 3.2 from 202. The electric field is blank. In the first 50 reviews, many are not in English. A UK review says 2 AAA and a torch, and that a pet-friendly claim failed at switch-on. Others call it a glorified torch, report a cell that lasted a day, or say a rat stayed after a field mouse left. One review mentions £19.95, which is not this captured price.
Pros
Cons
Best for: You want three LED units and a pieces field that already says 3.
Less suitable: You need the electric field filled in, or you are treating a quoted £19.95 in a review as this price.
Specifications
Common questions
Does the three-unit title match the pieces field?
Yes. The unit count is 3 and the number of pieces is 3. The part number is 70500 (3). The captured price is about £38.66.
What cells do reviews mention?
A UK review says 2 AAA and a torch. Another review mentions a volume control. Battery life in the sample runs from one day to still going after 20 days.
Is the electric field filled in?
No. That row is missing. The power source is battery. A UK review says the child and pet-friendly claim did not hold once the unit was switched on.
The 91920 is the wood unit at £32.45, with title and pieces both at one. Bullets claim 40 m², a changing frequency, and a housing you can separate for recycling. The star line is 3.1 from 58 ratings, and 35 saved reviews include a large share that are not in English. A UK review says you need 4 AA cells, which the spec table does not list, and that the unit can be switched off. Other reviews describe a fiddly battery door, a flashing LED that makes on hard to see, a dead unit in a multi-buy, and a household that stopped because children and a cat could hear it.
Pros
Cons
Best for: You want one wood-cased battery unit and will buy 4 AA cells yourself.
Less suitable: You want the cell type printed in the spec table, or a large UK-only review sample.
Specifications
Common questions
What batteries do the reviews name?
A UK review says 4 AA, not included. The spec table does not state the cell type. Another review says the battery door needs a screwdriver.
Is the housing wood on the listing?
The material is wood, the colour is brown, and a bullet says the electronics can be removed from the housing for recycling. Size is 8.3 x 8 x 3.3 cm and 140 g.
Does the listing answer pet safety?
The page asks if it is safe for pets and does not answer. A saved review says children and a cat could hear the tone, so that household stopped using it.
This 70500 row is the two-pack at £32.45 where the title, unit count and pieces field agree on two units. The title adds an LED and volume control, and the bullets claim 30 m² per device, not through walls. Stars are 3.1 from 44 ratings. Only 15 reviews are saved, and most are not in English. They mention short battery life, a dead half of the pair, a stuck switch, and rats that ignored units set 5 cm off the floor. One English review says it seems to work and that the cells last about a month. The children question on the page has no answer.
Pros
Cons
Best for: You want a two-piece LED pack whose pieces field matches the title.
Less suitable: You want a large English review sample or a spec table that names the cell size.
Specifications
Common questions
Does the two-unit title match the pieces field?
Yes. The unit count is 2 and the number of pieces is 2. The part number is 70500 (2). The captured price is about £32.45.
What do the saved reviews say about batteries?
Fifteen reviews are saved and most are not in English. They include cells flat after about a month, after three days, and a unit that died after the first battery change.
Does the listing say it is safe around children?
The page asks that and does not answer. Bullets say the frequencies are inaudible to humans. The title adds an LED light and volume control.
This is the £45.28 four-pack with LED and volume control in the title and no model or part number. Pieces, unit count and the title all say four, which is cleaner than the 70624 multi-pack titles. The claim is 30 m², size 7 x 7 x 4 cm, 35 g, red plastic. The star line is 2.6 from 17, the weakest and thinnest in this set, and only six reviews are saved. They include 2 AAA per unit, a torch light, sound adults could hear, and one working light out of four. That is not a base for a strong buy.
Pros
Cons
Best for: You have already decided on four small LED units and can accept a 17-rating sample.
Less suitable: You want a model number or a review count you can lean on.
Specifications
Common questions
Is there a model number?
No. Model number and part number are both absent. Unit count and pieces are 4. The title adds LED light and volume control.
How many reviews are saved?
The listing line is 2.6 from 17. Six reviews are saved, and several are not in English.
What did those reviews say?
One UK review says four red units take 2 AAA each. Another says adults could hear the sound and it did nothing for mice in a ceiling. Another review says only one of four lights worked.
Ten amazon.co.uk listings are on this page. The 1–10 score on each card follows the captured star line and review count. It is not a laboratory test and not a clearance. Shared review titles are not counted as a separate trial for every pack. Best value is the lowest price where the title pack matches the pieces field and the power row agrees with the battery bullets. The top pick is the two-unit 70632-B title, which leads on that card score at about £39.95. It is not a clearance.
Amazon evidence
40%Star rating and review count on the amazon.co.uk listing line. A large shared count is not added again for each pack ASIN. A line of 17 ratings cannot score like a line of several thousand.
Pack count versus pieces
25%The title count is checked against the pieces field. A two-unit or three-unit title with a pieces field of 1 is not treated as a confirmed multi-pack.
Power you can use
20%Bullets that say battery and no mains lead are checked against the power row. A row that says AC is not bought as a plug-in.
Range, hearing and placement
15%Seller area claims are 30 m² or 40 m² and do not pass walls. A published cycle for this class is partly audible to people, cats and dogs. Inaudible is seller language.
Start with the room, then the power row, then whether the pieces field matches the title. These are battery ultrasonic units for one closed space with no socket. A claimed 30 m² or 40 m² does not pass walls. The top pick is the two-unit 70632-B title at about £39.95. That is a card-score lead, not a clearance. Best value is the one-unit 70624 at about £26.95, where the title and the pieces field agree and the power row says battery. Nothing on this page is a laboratory test.
An ultrasonic mouse repellent in this category is a small battery unit for one closed room: a loft, cellar, garage, shed, or a storey with no socket. Seller bullets say the sound does not pass walls or furniture. A claimed 30 m² or 40 m² is a floor-area line, not a measured volume, and a house is one room at a time. Do not buy these as plug-ins. The bullets say battery and no mains lead, yet some listings still print power source AC.
Seller bullets say the sound does not pass walls or furniture. A 30 m² or 40 m² line is one closed room, not a storey. A second bay needs its own housing, and only if the pieces field confirms it is in the box.
Instructions for this class state about 12–24 kHz, with a few seconds on and a longer pause. People, cats and dogs can hear part of that band. Saved reviews describe a pulse about every 30 seconds. A pause is not proof the unit is off, and silence is not proof the mice have gone.
Titles that say two or three units can sit next to a pieces field of 1. The higher price does not buy a separate review trial when the same review titles appear on another pack. Check the pieces field before you step up from the one-unit price.
Buy for one closed volume. LED titles claim 30 m². The 70624, 70632 and wood titles claim 40 m². Neither figure passes a wall, so a house is one room at a time. Aim the speaker at the resting place, not into a cupboard door or a pile of insulation. Power has to be something you can use in that room. Bullets say battery and no mains lead. Three 70632 listings still say power source AC. The 70632 instructions hosted in the UK say 6 AAA, not included. Do not buy those rows as plug-ins.
Do not add shared parent reviews together. The 70624 family shares 3.6 from 3,198 ratings across the one-unit, the grey two-unit title and the three-unit title. Two 70632 titles share 3.7 from 3,990. The one-unit 70632-B has its own 3.3 from 235. The wood unit is 3.1 from 58. The LED four-pack is 2.6 from 17. A thin line is a weak base, even when the pieces field is clean. Hearing is part of the buy. The published band is about 12–24 kHz, partly audible to people, cats and dogs.
Three typical situations, each with a recommendation from this comparison.
You have one loft, cellar or garage bay and no mains socket. The Isotronic 70624 one unit is about £26.95, with 3.6 from 3,198 ratings. The title and the pieces field both say one unit, and the power row says battery. Those ratings are shared with two other 70624 pack listings. Saved reviews include a pulse people can hear. Skip it if you need a silent unit or a confirmed multi-pack.
You want one wood-cased battery unit and you will buy the cells. The Isotronic 91920 is about £32.45, with 3.1 from 58 ratings. A UK review says 4 AA, which the spec table does not list. The title and the pieces field both say one. Many saved reviews are not in English. Leave it if you need the cell type printed on the listing.
You are covering more than one closed space and you will only buy a pack whose pieces field matches the title. The Isotronic 70500 LED three-pack is about £38.66, with 3.2 from 202 ratings. Title and pieces both say three, and the power row says battery. A UK review says the pet-friendly claim failed at switch-on. Skip a multi-unit title whose pieces field says 1.
The top pick is the Isotronic 70632-B two-unit title. The captured listings do not show a clearance, so this is not an efficacy award. Card scores follow the amazon.co.uk star line and review count. They are not a laboratory test, and they do not mean mice will leave. It leads this set on the shared 3.7 from 3,990 ratings, at about £39.95. The three-unit 70632 title ties that star line at about £49.95. On both 70632 titles the pieces field says 1, and the power row says AC while the bullets say battery. The best value is the Isotronic 70624 one unit at about £26.95. It is the lowest price in this set, the title and the pieces field both say one unit, and the power row agrees with the battery bullets. The star line is 3.6 from 3,198 ratings, shared with two other 70624 pack listings, so that count is not three separate trials. Saved reviews include a pulse about every 30 seconds, a cat that avoided upstairs, and battery screws too tight to open.
Isotronic 70632-B two-unit title
Highest card score in this set, 3.7 from 3,990 shared ratings, at about £39.95. The three-unit 70632 title ties that star line at about £49.95. On both, the pieces field says 1, and the power row says AC while the bullets say battery. Not a clearance.
Isotronic 70624 one unit
About £26.95, the lowest price here. Title and pieces field both say one unit, and the power row agrees with the battery bullets. 3.6 from 3,198 shared ratings.
