The best Marten repellents, compared.
Top pick: HONGXIAN UK1314 ultrasonic strobe Best value: AROBA Kunagone pouch, model B2-WC4N-6KGO – About £5.99 with 3.8 from 108 reviews, the cheapest pouch that still has a review line. The about £5.86 single has no star line. Updated October 2026.
A marten repellent is a scent, an ultrasonic box or a spike belt you buy when something is chewing cables in a parked car, visiting a loft, or climbing a downpipe. In the United Kingdom the marten that lives here is the pine marten, and it is protected. Chewed car wires are far more often mice, rats or squirrels. Match the mechanism to the route: a spray or a hanging pouch if you will not wire anything, ultrasound if you can mount it off hot parts, or a stainless belt on a pipe you can reach from the ground. A useful listing agrees with itself on power and size. Every coverage figure is the maker's claim. A chemical scent can fall under biocides rules in Great Britain, and under EU rules in Northern Ireland. A code on a bottle is not a GB authorisation. A belt does not treat an engine bay. Do not trap a pine marten or block a den. How to choose under those limits is in the [marten repellent buying guide](/hub/pest-control/marten-repellent/sub/marten-repellent-buying-guide).

Question 1 of 2
Where is the animal getting in?
The HONGXIAN UK1314 is an ultrasonic box with an LED strobe at about £18.90, rated 4.8 from 15 amazon.co.uk reviews. UK comments in this file describe mice stopping in a car, a shed, a utility room, a kitchen and a loft. One unit arrived without batteries, and the charging method is unclear on the page. The power field says solar, while the bullets say a USB adaptor, 4 AA cells or vehicle power, and one UK review also mentions 12/24 V. The dimensions print 10 × 10 × 10 millimetres against a weight of 170 g, and those two figures are not reconciled. A 4.8 from 15 reviews is the highest star line here, and the score of 96 is that line times 20. The spec conflicts and the short file are why it stays off the top-pick badge, even though it holds the UK mouse comments in this set.
Pros
Cons
Best for: You weight the UK mouse comments and you will check which power lead is actually in the box.
Less suitable: You want one agreed power source and a printed frequency before you pay about £18.90.
Specifications
Common questions
Which power options does the listing give?
The power field says solar. The bullets say a USB adaptor, 4 AA batteries, or vehicle power. One UK review also mentions 12/24 V.
Did UK reviewers report mice stopping?
Yes in this file: car, shed, utility room, kitchen and loft. One unit arrived without batteries, and charging is unclear.
Do the dimensions match the weight?
The listing prints 10 × 10 × 10 millimetres and 170 g. Those two figures are not reconciled in the file.
The listing titled Kemo Marten repellent 12V is about £14.32, rated 4.4 from 281 reviews, while the brand field says Carpoint, the manufacturer is Service Best and the model is 0529532. The box is 5.1 × 9.1 × 2.8 cm and 87 g. A bullet says Frequency and does not give a kilohertz figure. The only UK review in the file describes a fit in 2016 for trips to Germany, because the buyer did not have a pine marten problem at home, and the arc of protection was unclear. That review also says the unit was wired to the battery. The 281-count is the second-largest file here. It still does not show a British engine-bay result, and the title and the brand field disagree, so mixed packaging is what the page itself suggests.
Pros
Cons
Best for: You already know this 12 V box and you accept the brand mismatch printed on the page.
Less suitable: You want UK comments about mice in a British car, or a frequency you can read in kilohertz.
Specifications
Common questions
Why do the title and brand differ?
The title says Kemo Marten repellent 12V. Technical details list brand Carpoint and manufacturer Service Best, model 0529532.
What does the only UK review say?
Fitted in 2016 for trips to Germany, because the buyer did not have a pine marten problem at home. Placement and the arc of protection were unclear.
Is a frequency number given?
No. A bullet says Frequency and does not give kilohertz.
Across 385 amazon.co.uk reviews, the BMUT MS-500 is a 500 ml water-based geraniol spray at about £16.00, with a 4.1 line. The bullets describe a mist and a jet for a car, a loft or a garage, and they say to repeat after a few weeks. One review in the file says every 3 to 4 days or the animal returns, so the two intervals sit side by side unresolved. The listing prints N-111079 and says the spray is made in Germany. In this scrape that string is a code on the page, and a GB biocidal authorisation is a separate HSE record that the file does not show. There is no UK review text in the raw sample, so the 385-count is the listing total rather than British comments you can read here. It is the top pick in this comparison because it combines the largest review file with a named ingredient and no battery leads.
Pros
Cons
Best for: You want a no-wiring scent spray with geraniol named on the listing and the largest review count in this comparison.
Less suitable: A downpipe climb, or a buyer who will only trust a row that includes UK review text.
Specifications
Common questions
Does the listing name a scent ingredient?
Yes. The bullets name geraniol and describe a water-based spray with no propellant gas.
Is there a UK authorisation number in the file?
The listing prints N-111079 and says the spray is made in Germany. The file does not call that number a GB BPR authorisation.
How often do reviewers say to respray?
One review says every 3 to 4 days or the animal returns. The bullets say repeat after a few weeks. The raw sample has no UK reviews.
The ISOTRONIC 84025 is two V2A stainless spike strips at about £17.92, rated 4.0 from 47 reviews, for a downpipe, a gutter or a tree. The listing says it is not electric. Bullets say a circumference of 50 cm or more needs extra strips, and end caps are stated. A UK reviewer calls assembly fiddly and says to shape the bands first. Another says the product is useless. Wider notes in the file mention cable ties that snap and caps that can slip. It is the climb barrier with the larger review sample in this set. A belt has no job on a wiring loom, so an engine-bay chew is a reason to leave this row closed.
Pros
Cons
Best for: You are stopping climbs on a downpipe or a tree, and you will shape the bands before you tighten them.
Less suitable: Chewed wires in an engine bay, or a gutter you cannot reach without working at height.
Specifications
Common questions
Will one strip fit every tree?
Bullets say a circumference of 50 cm or more needs several strips.
What do UK reviewers say about fitting?
One calls assembly fiddly and says to shape the bands first. Another says the product is useless.
Is it electric?
No. The listing says it is not electric and is hand powered.
The Technaxx TX-368 is about £9.98, rated 4.0 from 9 reviews, and it is the ultrasonic listing here with a printed band of 12–24 kHz and a 20 m² claim. The kit is 4 AA cells, with a claimed runtime of up to 45 days, a 12 V car cable or USB-C, plus an LED flash. Bullets state −10 °C to +60 °C and a built-in fuse. The reviews saved in the file are two short German comments, so there is no UK text to read. The bullets name rats, mice and martens, and the on-page question about rats has no separate answer. The 20 m² figure is the maker's claim. It is the row to open when you want a kilohertz range and a choice of power in one kit, with a short review file as the limit.
Pros
Cons
Best for: You want a printed frequency and a choice of AA cells, 12 V or USB-C, and you accept a nine-review file.
Less suitable: You are choosing only from UK review comments, which this scrape does not contain.
Specifications
Common questions
What runtime do the bullets claim on AA cells?
Up to 45 days on 4 AA batteries. A 12 V cable and a USB-C lead are also included.
Does the listing answer whether it works on rats?
The bullets name rats, mice and martens. The question field itself has no separate answer. Reviews in the file are two short German comments.
Is a temperature range stated?
Yes. Bullets say −10 °C to +60 °C and a built-in fuse. Weatherproofing is asked but not answered as its own field.
The AROBA Kunagone pouch, model B2-WC4N-6KGO, is about £5.99 and rated 3.8 from 108 reviews, with a claimed life of 3 to 6 months. Bullets say one pouch in the engine bay as prevention, two or three if an animal is already visiting, and four or five in a house or loft. The scent is described as a natural-enemy smell, and the ingredient is not named. Reviewers in the file say the animal left the car, or that the pouch was chewed in the bay or carried off. None of those review blocks are marked United Kingdom. The bullets say made in the EU, and the country of origin is Poland. It is the best value in this comparison because it is the cheapest pouch that still has a review count, and the chew-and-carry comments are the limit on that price.
Pros
Cons
Best for: You will not wire a battery, and you want the lowest pouch price in this set that still has a review sample.
Less suitable: You need a named ingredient and UK review text, or a spike belt on a downpipe.
Specifications
Common questions
What do reviewers say happens to the pouch?
Some say the animal left the car. Others say the pouch was chewed in the engine bay or carried off. None of the review blocks are marked United Kingdom.
How many pieces if an animal is already visiting?
Bullets say 2 to 3 in the engine compartment, or 4 to 5 in a house or loft.
Where is it made, on the listing?
Made in the EU in the bullets. Country of origin on the listing is Poland.
The Veddelholzer USB ultrasonic is about £24.26, rated 3.8 from 103 reviews, with a stated 23–44 kHz band, an LED flash and a 70 m² claim. Power is a 2 m USB lead, and reviews say there is no battery pack, so a spot without a USB supply is a poor fit. The listing says the frequency changes every 30, 60 or 90 seconds. There is no UK review text in the file. Non-UK comments include droppings beside the unit and a wildlife camera that still showed animals, alongside reports of a quiet garage. The 70 m² figure is the maker's claim. At the top of this folder's price band it asks you to pay more than the Technaxx for a USB-only box and a lower star line.
Pros
Cons
Best for: You have a USB socket in a garage or a loft and you want a printed 23–44 kHz range.
Less suitable: An engine bay with no USB point, or a shed you expected to run on cells.
Specifications
Common questions
Does it need batteries?
The bullets use a USB lead of 2 m. Reviews say there is no battery, so a garden without a USB supply is a poor fit.
What coverage is claimed?
Up to 70 m², with frequencies from 23 to 44 kHz changing every 30, 60 or 90 seconds.
Do reviews say animals still pass it?
Yes in the non-UK sample: droppings beside the unit, and a wildlife camera still showing animals. Other reviews report a quiet garage.
The vsshe twin is two engine-bay units at about £8.99, rated 3.7 from 7 reviews, with battery leads and a flashing light. Bullets say it runs for about 120 seconds after you stop, then shuts down when the vehicle moves, which is the listing in this set that states a driving cut-out. Red is positive and black is negative. The page asks for a range and the bullets give neither metres nor square metres. The only UK review says it worked at first, then rodents settled, and rats chewed the deterrent's own wires. Seven reviews is a small file. That chew note is why the low price does not take the best-value badge from the about £5.99 pouch.
Pros
Cons
Best for: You want two battery-lead units that claim to switch off while driving, and you will fuse the leads yourself.
Less suitable: You will not open the bonnet to wire a battery, or the loom already shows chew marks.
Specifications
Common questions
When does it switch on?
Bullets say about 120 seconds after the vehicle stops, then it shuts down when the vehicle moves.
What is the only UK review?
It worked at first, then rodents settled, and rats chewed the deterrent's own wires.
Is a range given?
No. The listing asks for the range and the bullets do not state metres or square metres.
The BigKing spike set is about £16.99, rated 2.9 from 4 reviews, with 20 wire elements, 40 protective caps and 10 cable ties. Bullets name trees, gutters and downpipes, and they recommend two belts per tree. They also name martens and raccoons. All three UK reviews are about cats: one says a neighbour's cat stayed off a bird nest, and two say cats ran past or climbed over two belts. The saved listing has no marten result. Four reviews is a very small sample, and 2.9 is the weak end of this table. The pack dimensions print 50 × 50 × 5 cm, which describes the carton more usefully than a fitted length. Open it only after you have decided on a wire belt and read those cat comments.
Pros
Cons
Best for: A tree or a gutter where you already want a wire belt and you accept a four-review file about cats.
Less suitable: An engine bay, or a buyer treating 2.9 from 4 reviews as evidence of a marten result.
Specifications
Common questions
Did UK reviewers stop cats?
One says it kept a neighbour's cat off a bird nest. Two say cats ran past or climbed over two belts.
What is in the box?
20 wire elements, 40 protective caps and 10 cable ties.
Does the file report a marten result?
No. The three UK reviews talk about cats only. Bullets also name martens and raccoons.
The Lucze four-pouch set, model KUN02EN, is about £24.99 and rated 2.8 from 13 reviews. The listing names citronella and says to place pouches under the bonnet, and it is also sold for foxes and badgers. Four of the six UK reviews say badgers walked past, moved the bags or shredded a pouch. The manufacturer line is KUNAGONE and the country of origin is Poland, while the brand field is Lucze. At about £6.25 a pouch it costs more per piece than the about £5.99 single, on a much weaker star line. The UK text in this file is a badger result. That makes it a weak pick when the job you typed was a marten or a rodent in a car.
Pros
Cons
Best for: You already want four citronella pouches and you have read the badger comments in this file.
Less suitable: A car-loom or marten job you hoped these UK reviews would support.
Specifications
Common questions
Did UK reviewers stop badgers?
No in four of the six UK reviews. Badgers walked past, moved the bags, or shredded a pouch.
Where does the listing say to put a pouch?
Under the car bonnet, to protect wires. The scent name on the listing is citronella.
Who is the manufacturer on the listing?
KUNAGONE, country of origin Poland. The brand field is Lucze.
The AROBA Kunagone single pouch, model ARKGDE001, is about £5.86, with a claimed life of 3 to 6 months and no star line in the saved listing. The bullets suggest one pouch in the engine bay as prevention, two or three if an animal is already there, and four or five in an active loft. The scent is described as a natural-enemy smell, and the ingredient is not named. The pouch weighs 40 g on the listing. With no customer-review line and no review text, this scrape cannot show whether a pouch stayed in the bay or was carried off. The shelf price is the lowest in the set. The empty review file is why the best-value badge sits on the other single, the about £5.99 row that does have 108 reviews.
Pros
Cons
Best for: You already use this exact Kunagone single and you are replacing it at the lowest shelf price in the set.
Less suitable: A first buy, when you want any review sample before a scent goes in the engine bay.
Specifications
Common questions
How many pouches does the listing suggest?
One in the engine bay as prevention, or two to three if an animal is already there. A loft uses one to two, or four to five if active.
How long does the maker say it lasts?
3 to 6 months.
Are there reviews in the file?
No. There is no customer-review line and no review text.
Eleven amazon.co.uk listings are scored from the star line alone. A 4.8 becomes 96, because the score is that average times 20. A row with no star line scores 0. Review volume, UK review text, a named ingredient, a printed frequency and listing conflicts do not add points. They are written in the assessment and they decide the awards. The top pick is the no-wiring spray with the largest review count, not the highest score. Best value is the cheapest pouch that still has a review line. This is not a repellent trial.
Amazon star line
100%The captured amazon.co.uk star average, times 20, is the whole score. A 4.8 is 96 and a 4.1 is 82. Review volume does not add points. Empty text, spec conflicts and price are not in this number.
Start with the animal and the route, then the mechanism, then the listing. A scent spray or pouch is for someone who will not wire a battery. Ultrasound is for a cool mounting point, with or without a light. A spike belt is for a downpipe or a tree, not an engine bay. Pine martens are protected. Chewed UK car wires are usually rodents. Shelf prices in this capture run from about £5.86 to about £24.99. The top pick is a no-wiring geraniol spray with the largest review file.
A marten repellent on amazon.co.uk is usually one of four things: a scent spray, a hanging pouch, an ultrasonic box with a light, or a stainless spike belt for a downpipe. In the United Kingdom the marten that actually lives here is the pine marten. It is a protected woodland species. Chewed car wires are far more often the work of mice, rats or squirrels, and the RAC and the AA also name foxes as able to chew. A stone marten in the engine bay is a continental pattern, not the default UK case.
The marten in Great Britain is the pine marten, and it is protected. Engine-bay damage here is described by the RAC and the AA as rodents, with squirrels and foxes also able to chew. A stone marten in the bay is a continental pattern.
Each score is the amazon.co.uk star line times 20. A 4.8 from 15 reviews scores above a 4.1 from 385 reviews. The Advertising Standards Authority has not accepted efficacy claims for electronic scarers on testimonials alone.
One listing says solar in the power field and USB, AA cells or vehicle power in the bullets. Another prints 10 mm dimensions against 170 g. Do not seal a loft while an animal may be inside, and do not spray a loom that is already cut.
Species comes first. Mammal Society and NatureScot treat the pine marten as the British species, protected since it sits on Schedule 5. Do not trap one, and do not block a den. If the damage is a UK car, the RAC and the AA describe mice, rats, squirrels and foxes, not a stone marten as the default. Mechanism follows the route. Scent is a spray or a pouch. Ultrasound is a box, with or without a flashing light. A spike belt is a climb barrier for a downpipe, a gutter or a tree.
Power has to match the place. A pouch or a spray needs no lead. AA cells or USB suit a cool mount. 12 V leads need a fuse and a fixing point off hot and moving parts. One twin states a shut-down when the vehicle moves. Other rows do not. None of these listings claim CAN-bus compatibility. A chemical scent can be a biocide under GB BPR, or EU BPR in Northern Ireland. A physical belt is outside that definition, on the HSE account.
Three typical situations, each with a recommendation from this comparison.
You will not wire a battery, and the chew is in a parked car rather than a protected den. The AROBA Kunagone pouch, model B2-WC4N-6KGO, at about £5.99 is the best value: 3.8 from 108 reviews, with a claimed life of 3 to 6 months. The ingredient is not named, and reviews describe pouches chewed or carried off. None of those blocks are marked United Kingdom. Skip it if you need a named ingredient or a spike belt.
In Scotland, Wales or a reintroduction area, identify the animal first. A pine marten den is a legal problem, and none of these rows is a licence to block one. If the visitor is a rodent and you want a named ingredient with no wiring, the BMUT MS-500 at about £16.00 is the top pick: geraniol, 4.1 from 385 reviews, and no UK review text in the file. Leave it if a den may still be inside.
You are stopping climbs on a downpipe or a tree you can reach, not chewed wires under a bonnet. The ISOTRONIC 84025 is two V2A stainless strips at about £17.92, with 4.0 from 47 reviews, the larger barrier sample here. A UK reviewer calls assembly fiddly. Another says the product is useless. Leave it if the gutter needs work at height.
The top pick is the BMUT MS-500 geraniol spray, 500 ml, at about £16.00. It is the no-wiring spray with the largest amazon.co.uk review file in this set, 4.1 from 385 reviews, and the bullets name geraniol. The numeric score is only the star line, so the HONGXIAN strobe at 4.8 from 15 reviews scores 96 and is not the top pick. The file has no UK review text, N-111079 is a printed code rather than a GB authorisation shown here, and repeat advice splits between a few weeks and 3 to 4 days. The best value is the AROBA Kunagone pouch, model B2-WC4N-6KGO, at about £5.99, with 3.8 from 108 reviews. It is the cheapest pouch that still has a review line. The about £5.86 single has no star line. Reviews describe pouches chewed or carried off. None of these scores is a repellent trial.
