The best Marten sprays, compared.
Top pick: Chemology peppermint rodent spray, 500 ml Best value: K2 cable coating spray, 400 ml – About £6.91 for 400 ml, the lowest shelf price with dozens of reviews (3.9 from 84), if you will accept a greasy film. Updated October 2026.
A marten spray is a liquid for cables, an engine bay, a garage, or the outside of a building, so a mammal is less likely to chew or linger. In the United Kingdom that label is easy to misread. Patrol reports name mice and rats as the usual animals on wiring, with squirrels and foxes also recorded. The pine marten that lives here is protected. A spray is not a tool for a den. You tell a suitable can from the listing. Check whether it is a scent that can fade or a physical film on hoses. Check the place the seller names, because a fence spray and a cable coating are different jobs. Check whether a repeat is stated in days or weeks, and whether any authorisation line is an HSE number. A German registration, a UFI, and the word natural are not that number. Do not spray a hot engine or an air intake. Wires that are already cut need a garage. How scent, coating, and a garden spray differ is in the [marten spray buying guide](/hub/pest-control/marten-spray/sub/marten-spray-buying-guide).

Question 1 of 2
Where is the animal a problem?
Chemology's 500 ml peppermint aerosol is £11.99 and aimed at mice, rats and other rodents on wiring and in vehicles. The title does not say marten. amazon.co.uk shows 5.0 from one review, written in the United Kingdom on 29 September 2026, which says the animals had gone and the parcel was well packed. There is no second review, so there is no criticism pattern to read. The bullets give no day count for a repeat. The seller says the plant-based formula is safe around people and pets when applied as directed, and the saved listing has no HSE number, so that sentence stays a seller claim. The page also prints 16 fluid ounces beside 500 ml. Rank 2 in Automotive Pest Repellent Sprays is Amazon's list position, not a result from this comparison. It is a peppermint option for car wires if one UK line is enough and you are not shopping for a marten-named can.
Pros
Cons
Best for: You want a peppermint spray that names car wiring, and a single UK review is enough for a trial.
Less suitable: You want a marten-named label, or more than one review before you trust a 5.0.
Specifications
Common questions
Does this listing say marten?
The title and bullets name mice, rats and other rodents, including chewing on car wiring. They do not name martens.
How many reviews are there?
One review, 5.0, written in the United Kingdom on 29 September 2026. It says the animals had gone. There is no second review to show a criticism pattern.
Does the listing prove it is safe around pets?
The seller says the plant-based formula is safe around people and pets when applied as directed. The saved listing has no HSE authorisation number.
The IRONTEK IT208 is a 300 ml lavender-oil aerosol at £20.45, made in France, with 4.2 from only six amazon.co.uk reviews. The bullets say to shake the can and spray from about 20 cm for 2–3 seconds per running metre on tension-free, clean and dry surfaces, and to repeat weekly if necessary. Reviewers call the jet strong, say it dries quickly with little visible mark, and note a light lavender smell. The same six texts say they cannot tell the spray from chance, one used it beside an ultrasonic device, and earlier chewing faults did not go away. The saved listing prints UFI HJYV-J5Q4-050C-YTTW, which identifies a mixture and is not an HSE authorisation. First available on 21 July 2026, so the sample is both small and new. It is a lavender option for an engine, a mower or a shed only if six reviews are enough for you.
Pros
Cons
Best for: You want a lavender aerosol with a written spray distance and you can accept a sample of six reviews.
Less suitable: You want a large review file, or you need an HSE number before you spray an engine bay.
Specifications
Common questions
What does the IRONTEK listing tell you to spray?
It names lavender oil and says to shake the can, spray from about 20 cm for 2–3 seconds per running metre, on tension-free, clean and dry surfaces, and to repeat weekly if necessary.
Is the UFI an approval to sell in Britain?
The saved listing prints UFI HJYV-J5Q4-050C-YTTW. It does not print an HSE authorisation number. A UFI identifies a mixture; it is not a star rating.
How many reviews are in the saved listing?
The listing line is 4.2 from 6 reviews. Those reviews describe easy spraying and say the writers cannot prove the spray is why animals stayed away.
Across 385 amazon.co.uk reviews, the BMUT MS-500 is a 500 ml water-based geraniol spray at £16.00, with a 4.1 line. The bullets describe a mist and a jet for a car, an engine bay, an attic, a house or a garage, and they say to repeat after a few weeks. One reviewer reports mice gone within 48 hours in a cluttered 10 m by 10 m space and found the geranium smell tolerable. Other drivers say the animal stayed out of the bay only when they kept spraying, and one who also fitted mesh preferred the mesh. Several reviews report no effect at all. A weak spray head that lets liquid run down the bottle is a repeated complaint. Those same reviews put the interval at every three or four days, which is shorter than the bullet. The listing prints German number N-111079 and says made in Germany, and this file does not show an HSE authorisation, so the top pick here is the size of the marten-named sample, not a UK approval.
Pros
Cons
Best for: You want a geraniol scent spray for a car, attic or garage, and you will respray, with the largest review file in this comparison.
Less suitable: You need an HSE authorisation printed on the page, or you want a coating that does not depend on smell.
Specifications
Common questions
Is the BMUT spray water-based?
The listing says the formula is water-based and free from propellant gases, and that it has no hazard symbols. It names geraniol and a mist or jet nozzle.
Is N-111079 a UK authorisation?
The saved listing prints N-111079 and says made in Germany. It does not print an HSE authorisation number.
What do the reviews repeat?
Some drivers report no further animal in the bay if they respray. Others report no effect. A weak nozzle that dribbles is a repeated complaint. One reviewer also fitted mesh and preferred the mesh.
At £6.91 the K2 K199 is a 400 ml aerosol sold as a slippery coating for cables, hoses and insulation, with 3.9 from 84 amazon.co.uk reviews. One driver used half a can on hoses and cables after an engine wash and reported no bite for four months. Other reviews say rats were still in the bay, and that any smell only helps if you renew the coat often. Several texts call the film greasy and then sticky, and say cleaning the bay took a long time. The seller says the effect is physical and not a biocidal product under Regulation 528/2012, and the saved listing has no HSE number. A live amazon.co.uk page on 21 October 2026 shows extremely flammable aerosol warnings that the raw capture omitted, so treat the can as a pressurised flammable product. The listing also notes that some products cannot be delivered outside mainland UK. It is the best value here on price beside a sample of 84, if you will accept the residue.
Pros
Cons
Best for: You want the cheapest cable coating in this set and you will live with a greasy film on hoses.
Less suitable: You want a water-based scent with no sticky residue, or delivery outside mainland UK if the listing blocks it.
Specifications
Common questions
How does the K2 listing say it works?
It says a slippery layer makes cables and hoses harder to bite, and that the effect is physical rather than a biocidal product under Regulation 528/2012.
What do reviews say about the finish?
Several reviews call the film greasy and then sticky, and say cleaning the bay took time. Comments on whether animals stayed away conflict.
Where does the listing say to use it?
On cables, hoses and insulation in the engine bay, and also in garages, barns, attics and storage rooms. The saved listing also notes a possible delivery limit outside mainland UK.
Substral Celaflor model 1300 is a 500 ml ready-to-use spray at £22.83 for dogs, cats and martens on fences, walls, drives and covered areas. amazon.co.uk shows 3.5 from 952 reviews, the biggest count in the file, and the written themes are garden fouling rather than engine bays. Some reviewers say dogs or cats stopped fouling, and several call the smell mild. Many more say cats were back within hours or a few days, that rain washes the spray off, and that a few days of effect sits against the seller's claim of up to 6 weeks. A gummed trigger and a child-resistant cap that is very hard to open also come up. The saved listing prints 50 g for a 500 ml bottle, which is the figure as captured. No ingredient and no HSE number are named. It is the garden row in this set if the problem is a dog or a cat on a path, and a poor stand-in for chewed car cables.
Pros
Cons
Best for: You want a fence and drive spray for dogs or cats, and you will respray after rain.
Less suitable: Chewed car wiring, or anyone who reads 952 reviews as evidence for an engine bay.
Specifications
Common questions
Is this an engine-bay cable spray?
The bullets say fences, walls, drives and covered areas around the house, for dogs, cats and martens. They do not describe a cable coating.
Do the reviews support six weeks?
The seller claims up to 6 weeks. Many of the 952 reviews describe cats or dogs returning within days, and some say rain removes the effect. A gummed trigger is also reported.
Why is the weight 50 g?
That is the item weight printed in the saved listing for this 500 ml bottle. It is copied as printed, not corrected.
STOP&GO model 07520 is a scent concentrate at £12.69 with glue-on fragrance reservoirs for a car, a home, a garden or a carport. The saved listing states no volume in millilitres and no chemical name. The listing says you glue the reservoirs in place and respray them, and it gives no day count. There is no customer-review line and no review text, so the comparison score stays at 0. The pack is listed at 180 g and 5 x 18 x 5 cm. Its best-sellers rank sits in Automotive and in Motorbike Theft Protection, which is a different shelf from the rodent-control rows. No authorisation number appears in the file. It is a pad system to consider only if you already know this concentrate and you do not need stars or a named ingredient.
Pros
Cons
Best for: You want glue-on scent pads and you can buy with no customer reviews in the file.
Less suitable: You want a rated aerosol, a named oil, or a coating for cables and hoses.
Specifications
Common questions
Is STOP&GO a ready aerosol?
The listing calls it a concentrate used on enclosed fragrance reservoirs that you glue in place and respray. It does not state a volume in millilitres.
Is there a customer rating?
The saved listing has no customer-review line and no review text, so there is no star rating to show.
Where does the listing say to use it?
Car, home, garden or carport. It does not name an active substance or an authorisation number.
Six amazon.co.uk listings are scored out of 100 from the files captured on 19 October 2026. The star block is (stars divided by 5) times 70. The sample block is log10 of (review count + 1) times 10, capped at 30. A missing star line scores 0. Price, a sticky film, a German registration number, and a missing HSE line are written in the assessment and do not add points. This is not a spray trial and not a count of chewed cables. The top pick is the highest score. Best value is the lowest shelf price that still has dozens of reviews.
Star rating
70%The star block is (amazon.co.uk stars divided by 5) times 70. A 4.1 becomes 57.4 before the sample term. A 5.0 becomes 70. A missing star line scores 0 for the whole card, which is why a concentrate with no review line sits at 0.
Review sample
30%The sample term is log10 of (review count + 1) times 10, capped at 30. A file of 385 reviews adds about 26 points. A file of one review adds about 3. The two terms are added and rounded. A 5.0 from one review therefore scores below a 4.1 from 385 reviews.
Start with the animal and the place, then the mechanism, then the review sample. A scent can fade. A physical film can turn greasy. A fence spray is not evidence for an engine bay. Shelf prices in this capture run from about £6.91 to about £22.83. The top pick is the BMUT geraniol spray. The best value is the K2 cable coating. Nothing on this page is a spray trial in a lab, and none of these listings was matched to an HSE authorisation number.
A marten spray is a liquid you apply so a mammal is less likely to chew cables or linger in a bay, a garage, or around a building. In the United Kingdom the product name is a poor guide to the animal. The AA names mice and rats as the usual animals on vehicle wiring, with squirrels and foxes also recorded. The pine marten that lives here is protected. A neighbour's cat on a path is a different job again.
The AA names mice and rats as the usual animals on vehicle wiring, with squirrels and foxes also recorded. A can that says marten does not make a stone marten the animal in a British engine bay. A pine marten in a loft is a protected species, not a basket choice.
The 500 ml garden spray has 3.5 from 952 reviews, and the written themes are dogs and cats on paths. Rain and a return within days come up often, against a seller line of up to 6 weeks. That file is not evidence for chewed car cables.
N-111079 on the geraniol listing is a German number. A UFI identifies a mixture. HSE product type 19 covers repellents, and Great Britain needs a GB authorisation. None of these six listings was matched to an HSE number in this research.
Car wiring parked in Britain points to mice, rats, squirrels, or foxes. A pine marten in a loft is a legal problem, not a reason to spray a den. A neighbour's cat is a fence-and-drive job, not an engine spray's job. Scent (geraniol, lavender, peppermint, or a pad concentrate) can fade. Reviews often say respray in days or a few weeks. The physical film is the alternative, and several reviews call it greasy then sticky.
The largest marten-named sample is the geraniol spray, 4.1 from 385 reviews, at about £16.00. The cheap coating with dozens of reviews is 3.9 from 84, at about £6.91. One five-star UK line and six lavender reviews are thin samples. A missing star line scores 0. HSE lists product type 19 as repellents and attractants and product type 14 as rodenticides. Repellents can be biocides even when they do not kill. Great Britain needs a GB authorisation.
Three typical situations, each with a recommendation from this comparison.
You want a geraniol scent for a bay, an attic, or a garage, and you will respray. The BMUT spray is about £16.00 for 500 ml, with 4.1 from 385 reviews, the largest marten-named sample here. Some drivers report the animal stayed out when they kept spraying. Others report no effect, and a weak nozzle comes up more than once. The listing prints German number N-111079, not an HSE number. Skip it if you want a coating that does not depend on smell.
You want the lowest shelf price that still has dozens of reviews, and you will live with a greasy film on hoses. The K2 coating is about £6.91 for 400 ml, with 3.9 from 84 reviews. One driver reported no bite for four months. Other reviews say rats were still in the bay, and that cleaning the residue took a long time. The live page shows extremely flammable aerosol warnings. Skip it if you want a water-based scent with no sticky film.
The problem is a dog or a cat on a fence, a wall, or a drive, not chewed car cables. The Substral spray is about £22.83 for 500 ml, with 3.5 from 952 reviews. The seller says up to 6 weeks. Many reviews say cats were back within days and that rain removes the effect. Those reviews are garden fouling, not an engine bay. Skip it if you are reading 952 ratings as proof for car wiring.
The top pick is the BMUT geraniol marten spray, 500 ml, at about £16.00. It is the highest score: 4.1 from 385 amazon.co.uk reviews, and it is the largest marten-named review file in this set. Reviews also report no effect, a weak nozzle, and a shorter repeat than the listing. N-111079 is a German number, and this scrape does not show an HSE authorisation. The best value is the K2 cable coating spray, 400 ml, at about £6.91, with 3.9 from 84 reviews. It is the lowest shelf price that still has dozens of reviews. Several reviews call the film greasy and then sticky. Substral scores 79 from 3.5 and 952 reviews and is not the top pick, because those reviews describe dogs and cats on paths. None of these scores is a laboratory spray trial.
K2 cable coating spray, 400 ml
About £6.91 for 400 ml, the lowest shelf price with dozens of reviews (3.9 from 84), if you will accept a greasy film.
