GreenHero Marten-Ex Spray against Marten Damage

What really helps against martens?

An effective remedy against martens is a marten spray that releases a smell martens find unpleasant. The smell is so intense for martens that they choose a different direction. The key to driving martens away is knowing what they dislike and reducing their comfort in the engine compartment or loft. Eventually, martens leave of their own accord. The active substance takes effect quickly and the marten looks for different shelter.

In addition to the smell, the sprayed particles also contain an unwelcome taste component. If marten damage has already occurred, action should be taken quickly, as other martens may also be attracted and some have already caused extensive damage to entire engine compartments. Because the marten spray masks the body scent of other martens, the animals can no longer recognise each other by scent and consequently stay away.

Other marten control substances exist, but these often contain toxic ingredients and are not repellents. They kill the animal, which dies in agony, or cause lasting health damage. We therefore rely on repellent products from the outset.

Which marten protection is best?

Our aim is to support the conservation of the marten while ensuring that it does not become a hazard to people and vehicles. Effective protection requires an understanding of the animal's preferences and aversions. For us, marten spray was the only solution, and it is also very popular with our customers.

As an alternative, or in addition to this form of protection in lofts and engine compartments, dogs and cats are very effective. They pose a potential threat to martens, which is why martens flee at the mere sight of their hair. Keeping a dog or cat therefore provides good long-term protection against martens such as the stone marten.

Martens also strongly dislike toilet blocks. However, these options involve considerable effort: toilet blocks cannot be fitted everywhere in the engine compartment, cat and dog hair is not easy to obtain without pets, and other methods are often complicated, costly or time-consuming to install. Marten spray solves these problems quickly with a single product.

Which cars do martens prefer?

Martens obviously know nothing about car brands, yet statistics show that marten bites occur more frequently in certain vehicles and brands. Regardless of the statistics, it is the type and manufacture of the components in the engine compartment that matter. Martens prefer engine compartments that give them more room to move. Other martens then inevitably enter the engine compartment, which in turn leads to marten bites.

Marten spray also masks the smell of fishmeal, which is often used in the manufacture of certain vehicle parts. As martens feed on it, they search for the source and find it in the engine compartment. Marten spray counters this by releasing a smell martens cannot tolerate and neutralising the smell of fishmeal. The following car brands in particular require regular marten protection with marten spray:

• BMW
• Mercedes
• VW
• Skoda
• Audi

Owners of vehicles from other manufacturers are also occasionally affected by marten bites, and not only in summer. In winter, martens use the warm engine compartment as protection from the cold. They do not always bite into cables and hoses at the same time, but if they detect the scent of another marten, this inevitably leads to biting. Marten spray is therefore advisable regardless of the vehicle model.

Marten spray or ultrasound?

Marten spray is a very good choice and drives martens away reliably. Ultrasonic devices can also be useful: they disturb the marten and impair its field of vision, so that it turns away in time and does not reach the engine compartment. However, as ultrasonic devices cost more to buy and run than marten spray, marten spray is the preferable option.

Marten spray is also easy to store and very economical in use, making it suitable for an entire vehicle fleet. Store the spray in a cool place, protected from direct sunlight and out of reach of children. Read the instructions on the packaging before use and follow each step.

Anti-marten spray after a marten bite?

If there are already signs of a marten bite, more than marten spray is needed: the marten's scent must be removed completely. A full engine wash is therefore essential, as this is the only way to remove the scent marks and prevent further bites. In lofts, all marten residues must also be removed. Marten spray should only be used after this and then prevents renewed marten bites.

After marten spray has been applied, martens look for a different place. For the spray to work, all product information should be read carefully. The marten spray is supplied in a practical, ergonomic bottle with spray head, which makes it easy to apply the scent and taste components.

Marten spray – getting rid of persistent biters

Martens put drivers' patience to the test in particular. They settle unnoticed in engine compartments and can cause serious damage there, resulting in costly repairs. Driving safety is also at risk if martens bite through a vehicle's lines. However, these nocturnal, cat-sized animals do not only target engine compartments.

They often settle in garages or lofts, where they seek shelter and usually remain undetected. Marten spray is an effective means of combating stone martens and other animals and drives them away very reliably.

Why martens bite through cables

Many people wonder why martens prefer engine compartments as shelter. Especially in the cold season, martens look for shelter. Gardens offer no warm spots, whereas a recently parked vehicle is still pleasantly warm inside. Here the marten finds protection and can withstand the low temperatures.

If another marten has already settled in the vehicle's engine compartment, the newcomer detects the previous occupant by its scent marks. These scent marks increase the marten's aggression, and as a result it bites through plastic parts and hoses on the vehicle. If a car suddenly has difficulty starting, a marten should always be considered as a possible cause.

Getting rid of martens quickly

We feel closely connected to nature, and this includes an alternative form of marten protection: a high-quality marten spray based on geraniol that achieves good results.

Many marten sprays are less effective. Many users are looking for a quick solution. Our marten spray takes effect quickly, but the application has to be repeated. In return, it offers long-term marten protection.

Marten repellent spray with an effective active substance formula

Martens in the loft and looking for a good marten spray? We know which substances martens reject. These substances are unpleasant for martens – comparable to a smell a person finds repulsive and therefore avoids. The same applies to martens: if they smell the ingredients of our marten spray, they quickly move away. Other animals also stop seeking shelter in engine compartments, lofts or other areas around the building.

Importantly, the engine compartment is difficult to reach with a liquid repellent applied with a cloth, as not all areas can be covered. Marten spray is different: the fine spray mist reaches all surfaces. This masks the marten's scent marks with the scent of the anti-marten spray, so the animals no longer feel comfortable.

Applying the marten repellent

The marten spray is supplied in a practical 500 ml bottle with a pump spray head at the top. The spray head atomises the liquid, which helps to reach all areas, including hard-to-reach parts of the engine compartment, quickly and easily. This ensures that martens no longer enter the engine compartment after application.

Shake the marten spray vigorously before first use. Open windows if necessary and wear protective clothing. Make sure there are no open drinks or food in the room. Move children and pets to another room beforehand. Turn the spray head by 90 degrees; the bottle is now ready for use. The surfaces to be treated must be dry. Spray every area. Repeat this procedure every 4 weeks to drive martens away or make them move elsewhere.

Preventive measures: what helps against martens?

The spray for engine compartments is also suitable as a preventive measure, including for vehicles that have not yet been attacked. The marten repellent for cars and buildings is a good option in both winter and summer. If typical marten traces are found in a loft, only use the repellent after the animals' access point has been closed.

It is also important to remove droppings and other residues; thorough cleaning is necessary. Wear protective clothing for this as well. Wash hands thoroughly after cleaning and after applying the spray. Then store the spray out of reach of children.
