What is the difference between PMD (p-menthane-3,8-diol) and DEET?

PMD (p-menthane-3,8-diol) and DEET (diethyltoluamide) are the two most effective approved insect repellents—but they differ fundamentally. DEET is a synthetic active ingredient that has been used since the 1940s and is proven to dissolve plastics, can cause skin irritation, and is considered concerning for infants. PMD, on the other hand, is obtained from the natural oil of lemon eucalyptus and is the only plant-based active ingredient that the US CDC (Centers for Disease Control) certifies as having an effectiveness against ticks and mosquitoes comparable to DEET. The World Health Organization (WHO) explicitly recommends PMD as a natural DEET alternative—a decisive advantage for everyone who wants to consciously avoid synthetic chemicals.

Does the protection still last after sweating or in the rain?

The protective effect of PMD-based sprays is reduced by sweating, water, and physical activity—just like all other insect repellents, including those containing DEET. The stated protection time of up to 8 hours applies under normal conditions. In the case of intense physical activity with heavy sweating, when bathing, or after heavy rain, reapplication is recommended to maintain protection. Especially during activities in midsummer or in tick-heavy areas: it's better to respray once more than to go without full protection. The same applies when using it on dogs—the spray should be reapplied after bathing or swimming.

Does the spray reliably protect against Lyme disease and TBE—or do I need additional measures?

The spray is an effective first line of defense: it significantly reduces the risk of a tick bite by keeping ticks at a distance. For comprehensive protection against Lyme disease and TBE, however, the spray should be combined with further measures: wear long clothing that covers the skin and additionally spray the product onto your clothes, carefully check your entire body for ticks after spending time in nature (especially the back of the knees, armpits, groin, and neck), and remove any ticks found immediately and completely. There is a recommended vaccination against TBE. Lyme disease is not vaccine-preventable—here, mechanical tick defense through spray and clothing is all the more important.

Can I apply the spray to clothing—and how long does the protection last on textiles?

Yes, the spray can be applied to light textiles as a supplement—this is particularly useful on areas of the body covered by clothing or for sensitive skin. The effect usually lasts a bit longer on textiles than on the skin, as the spray is not broken down as quickly by sweat or body heat. Important to know: PMD does not contain solvent-based substances like DEET and does not attack synthetic fibers—clothing made of polyester, nylon, or other synthetic materials remains undamaged. For best results, spray the clothing lightly from a distance of about 20 to 30 cm and let it soak in briefly before putting it on.

Why shouldn't the spray be used on cats?

Cats lack the liver enzyme UDP-glucuronosyltransferase, which is responsible for breaking down many substances—including essential oils—in dogs and humans. Without this enzyme, cats cannot metabolize eucalyptus oil and its active ingredient p-menthane-3,8-diol: the substances accumulate in the body and can lead to symptoms of poisoning such as salivation, vomiting, tremors, and in severe cases, liver failure. This also applies to small amounts that a cat might ingest while licking its fur. There are specially formulated, safe insect protection alternatives for cats—these should only be used after consulting a veterinarian.

How do I store the spray correctly – and how long does it last?

The spray should be stored in a cool, dry place away from light—direct sunlight and temperatures above 30 °C can impair the stability of the active ingredients. As this is a pressurized container, the spray must never be stored in direct sunlight in a car, especially in summer. Please refer to the packaging for the expiration date. Check opened bottles after the season—a change in smell or color can indicate a loss of quality. Always keep the spray out of reach of children and do not combine it with other liquids or transfer it to other containers.

Yara Natural Protection – Anti-Tick & Mosquito Spray for Humans & Dogs (100 ml, Vegan)

Natural spray against ticks, mosquitoes, and other insects. In a 100 ml spray bottle. Also ideal for on the go.

Pure Natural Protection: Suitable for humans (from 2 years old) and dogs

The “Yara Insect & Tick Protection Spray” is the perfect way to protect you and your family safely from insects and especially ticks – in a completely natural way. In the wild, not only annoying mosquitoes but also dangerous ticks that can transmit diseases often lurk. Our spray offers you up to 8 hours of reliable protection, so you can fully concentrate on outdoor adventures without worrying about unpleasant bites or stings. Ideal for hikes, forest walks, camping, or everyday use in the garden, this spray is a must-have for anyone who loves spending time outdoors.

Natural Benefits:

100% vegan and purely plant-based – environmentally friendly and gentle on the skin
Up to 8 hours of reliable protection against ticks, mosquitoes, and horseflies
Natural active ingredient (15% p-Menthane-3,8-diol) from lemon eucalyptus
Safe for the whole family (children aged 2 and up) and suitable for dogs
Free from aggressive chemical additives
Compact 100 ml spray bottle – ideal for on the go and outdoor activities

100% Vegan and purely plant-based – for the sake of the environment and your skin

A special highlight of the spray is its vegan and purely plant-based formula. The main active ingredient p-Menthane-3,8-diol is derived from the oil of the eucalyptus plant (Eucalyptus citriodora), a natural source with amazing insect-repelling properties. In a time when environmental awareness and sustainability are becoming increasingly important, we deliberately rely on a formula that is free of animal ingredients and poses no burden to nature. The spray contains no chemical additives, which are often found in conventional insect repellents and can irritate the skin. This way, you protect not only yourself but also the environment – without compromise.

Gentle and effective protection – also suitable for dog skin

Since the main active ingredient of the spray, p-Menthane-3,8-diol, is derived from natural eucalyptus oil, the product is gentle on the skin and pleasant even for sensitive dog noses. The plant-based ingredient effectively repels ticks and other insects without irritating your dog’s skin or leaving unpleasant odors. The spray contains no aggressive chemicals. It offers a plant-based alternative to conventional, chemical-based insect repellents, which are often harsher on the skin and can harm the environment.

Effective Tick Protection – Safe Protection from Invisible Dangers

Ticks are more than just an inconvenience. They can transmit diseases like Lyme disease and TBE, which can have serious health consequences. Our “Yara Insect & Tick Protection Spray” reliably protects you from these small but dangerous bloodsuckers. Thanks to the special plant-based formula, ticks are kept away from you without having to expose yourself to aggressive chemicals. The protection remains active for up to 8 hours, so you can enjoy your time outdoors with peace of mind. Especially for families with children, this protection is invaluable, as the spray is suitable for children aged 2 and up and is gentle on the skin.

The Power of Eucalyptus – Active Ingredients from Nature

Why did we choose p-Menthane-3,8-diol from eucalyptus oil as the active ingredient? It’s simple: this ingredient offers an excellent yet gentle effect against insects and ticks. The special scent of eucalyptus oil repels insects without being unpleasant for humans. Eucalyptus oil has been used as a natural repellent for centuries, and modern research has confirmed its effectiveness. In addition, p-Menthane-3,8-diol is well-tolerated and does not cause skin irritation, which is a great advantage, especially for sensitive skin. You benefit from the natural repellent power of eucalyptus without having to accept the disadvantages of chemical active ingredients.

Easy Application and Safe Protection – for All Outdoor Enthusiasts

Applying the spray is quick and easy: apply it evenly to all exposed skin areas, even under light clothing, to ensure comprehensive protection. The eye area should be avoided. If necessary, for example after heavy sweating or during particularly intense activities, you can easily reapply to maintain protection. Thanks to its compact size, the spray fits in any bag and is always at hand when you need it. This way, you are always optimally protected, anywhere – whether on a short walk or an extended hike.

Application for Humans

Note: Despite its plant-based nature, the spray should first be tested on a small skin area before widespread application to rule out skin reactions. If no irritation occurs, it can be used without hesitation.

Directly on the skin: The spray can be applied completely and evenly to exposed skin areas, but only on intact skin. Eye areas must be avoided.
Spray on clothing: Alternatively or additionally, the spray can also be applied to light textiles. This is particularly practical if sensitive skin areas need to be protected or if additional protection is desired.
Reapplication: If the effect wears off, the application can be repeated, especially during longer outdoor stays.
For children: The spray is suitable for children aged 2 and up. However, it should not get into children’s hands and should always be applied by an adult.
Duration of protection: The protection reliably works against mosquitoes for up to 8 hours and also protects against ticks and horseflies.

Application for Dogs

Note: The product is plant-based, but we still recommend testing it on a small area of fur first to rule out possible skin reactions.

Spray on fur: The spray can be applied in a light amount to the dog’s fur. Care should be taken to avoid the head area (eyes, nose, and mouth).
Prevent licking: After application, the dog should be prevented from directly licking the treated fur. For sensitive dogs, it is advisable to test the product on a small area first.
Supplementary application on textiles: If the dog wears a blanket or protective clothing, the spray can also be applied to these. This offers additional protection without direct skin contact for the animal.

Note:
Cats can metabolize essential oils poorly or not at all. Therefore, please do not use on cats.
