Natural repellents based on powerful ingredients : an effective defence against insects in our homes

The fight against crawling and flying insects invading our homes can be waged naturally thanks to a range of powerful plant-derived ingredients. In addition to insects, these natural active ingredients can also act as repellents for other animals, such as moles, slugs and even snakes. These repellents offer an environmentally and human health-friendly alternative to harsh chemicals. Let's find out how ingredients such as geraniol, eucalyptus citriodora, margosa, vegetable pyrethrum and essential oils can play a crucial role in defending our living spaces.

1. Geraniol : Geraniol, a natural compound found in certain essential oils such as citronella and geranium, has repellent properties against a variety of insects, including mosquitoes and flies. Geraniol-based products can be sprayed into rooms or applied to the skin to keep insects away.

2. Eucalyptus Citriodora : Eucalyptus citriodora essential oil is known for its strong lemony aroma. It is effective against mosquitoes and other biting insects. Mixed with a carrier oil, it can be applied to the skin or used in diffusers to keep insects at bay. Penn'Ty Bio offers a range of lemon eucalyptus products to protect you from insect bites

3. Margosa (Neem) : Margosa extracts, derived from neem seeds, have well-established insect repellent properties. The bitter odour and repellent action of margosa make it a valuable ingredient in sprays and lotions for protection against insects.

4. Plant pyrethrum : extracts of plant pyrethrum are obtained from the flowers of certain varieties of chrysanthemum. They are used to make natural contact insecticides or repellents. Pyrethrum is effective against a wide range of insects, including ants, flies and cockroaches.

5. Essential oils : As well as geraniol and eucalyptus citriodora, many other essential oils can be used as natural repellents. Peppermint, clove, lavender and lemon are just a few examples of oils with repellent properties. They can be mixed with water to create sprays or added to cleaning products.

Using natural repellents based on these ingredients offers a solution that is not only effective, but also without the drawbacks of traditional chemicals. However, it is important to note that although these options are natural, some people may be sensitive to essential oils or plant extracts. Before using these products, it is advisable to carry out a skin patch test and follow the manufacturer's instructions.

By adopting natural repellents, you can create a hostile environment for unwanted insects, while keeping your home and the surrounding ecosystem safe.

Lutter contre les insectes piqueurs sur une vache

ALT'O ZINSECT Spray is an active repellent against these biting and sucking insects. It provides an effective and long-lasting barrier for up to 4 to 5 days (without washing or sweating). This product has been formulated with 100% active plant ingredients. It is safe for your pets and for humans (under normal conditions of use of course!). For example, this insect repellent for animals will be ideal against flies on dairy cows, flat flies or horse flies on horses, donkeys, ponies, ticks on ruminants, sarcoptic mange on pigs, red lice on chickens, etc.

It is applied directly to the animal's coat, from the ears to the rump. For ticks, apply to the lower parts of the animal's body: legs, crotch and base of the neck, possibly up to mid-flank. Resistant to perspiration and light rain but not to shampoos, this insect repellent is marketed in the form of a spray (1 litre) or a gel (500ml), packaging that will allow total protection of your horse or pony for a season (or much more if your animal is smaller). Due to its high concentration, a small amount is enough to protect your animal (maximum 50 ml/application for a 600 kg short-haired animal).

You can also use ALT'O ZINSECT spray on the surfaces of buildings housing animals against flying or crawling insects (stables, boxes, kennels, henhouses, aviaries). However, the product must be cut with water (one volume of ALT'O ZINSECT spray to be diluted in the same volume of cold, clean water), then sprayed on the interior walls of the buildings.

Why does my horse attract flies ?

Lutter contre les insectes piqueurs sur votre cheval

Flies on your horse are naturally attracted by traces of dried or wet sweat and dirt. In the animal's hair and mane, flies find everything they need... a real larder! And flies are not the only ones, flying insects that find it easy to eat have quickly understood the good plan! Insects such as horseflies and mosquitoes that are present on your horses or ponies also take advantage of the opportunity to bite the horse's skin and suck the blood after depositing their saliva, thus facilitating the digestion of their meal. Applying fly protection to the horse's head, body and legs is the best solution. The presence of excrement (dung, manure, etc.) is also a source of excessive fly presence around the animal.

The equines most exposed to flies are obviously horses living in the pasture day and night, without a shelter to protect them from the heat, or living near water in wet and marshy pastures. Furthermore, unlike cats and dogs who regulate their temperature through their mouths, horses regulate their temperature through sweating. In the event of a heat peak or intense effort, the horse will therefore sweat. Insects are particularly fond of sweat with a very salty taste and will inevitably attack the horse. Flies also like dust and dirt and are attracted to dirty horses in the pasture.

Focus on the main active ingredients

actifs Eucalyptus citronné, pyrèthre végétal et géraniol

Eucalyptus citriodora : Lemon eucalyptus oil is a plant extract concentrated in P-menthane-1,8 diol molecules. This substance has a strong repellent effect against many pests (mosquitoes, ticks, lice, flies, snakes, small mammals, etc.). Its activity is comparable to the 3 main substances on the market (DEET, Icaridine and IR3535™). Lemon eucalyptus oil is the only substance of natural origin that provides a significantly long-lasting repellent effect. Its repellent effectiveness has been proven in the laboratory and in the field, including on tiger mosquitoes.

Pyrethrum : Pyrethrum is a plant insecticide extracted from dried chrysanthemum flowers. Kenya is the largest producer of pyrethrum, followed by Tanzania. The term "pyrethrum" refers to the powder extracted from dried chrysanthemum flowers, while the term "pyrethrins" refers to the six active compounds contained in this powder. It is these active ingredients that have a strong neurotoxic effect on insects. Pyrethrum Extract is effective on many of them. It acts on the nervous system of insects, causing them to suffer from lightning muscle paralysis. It is one of the most powerful knock-down agents. Pyrethrum can be used in organic farming. It is biodegradable and its action is limited in time because it degrades in the light. 

 Geraniol : Geraniol is obtained by fractional distillation from the Cympobogon Winterianus Jowitt plant by extracting all impurities without any chemical means. It is a member of the monoterpene alcohol family. Geraniol is a colourless liquid with a pleasant rose odour. Geraniol is naturally present in many fruits, vegetables, spices and essential oils. Thanks to its floral scent and special properties, geraniol is used in many fields of application (cosmetics, pharmaceuticals, food, detergents) and in particular as an anti-insect solution. It is also an excellent larvicide and ovicide. It acts at all stages of metamorphosis (egg, larva, adult) by suffocation and dehydration by acting on the chitin. It is often found in insecticide or repellent products to reinforce their action. This substance is effective over a wide spectrum.

Application of ALT'O ZINSECT on the animal

1 - Shake the can vigorously before use

2 - An application consists of spraying the product in fine droplets all over the body, without trying to completely wet the animal. Do not apply too much product. This product is used by spraying the areas to be protected, without dilution, on the animal's coat. Depending on the sensitivity of the animal, spray directly or use a pad, or distribute by hand.

Against ticks, apply to the lower parts: legs, crotch and base of the neck, possibly up to mid-flank.

3 - Apply only to dry hair

4 - In periods of heavy attack and for optimal protection, combine ALT'O ZINSECT Gel once a week on hairless areas.

Note : 1 pull of the trigger (spray) is equivalent to approximately 3 ml.

Chickens : 6 to 8 ml (2 to 3 sprays): it is necessary to raise the feathers a little during the treatment because it is often in these areas that the red louse is present. This treatment is sufficient for about 10 days.

Pony/calf : 15 to 25 ml (5 to 8 sprays)

Horse/cow : 15 to 50 ml (5 to 16 sprays) depending on whether the protection is local (e.g. head) or total. 1 litre of ALT'O ZINSECT spray corresponds to approximately 45 treatments, i.e. more than 4 months of protection for a horse. Indeed, 8 pressures for a horse: 2 on each flank, 1 on the midline, 1 on the buttocks, 2 on the chest. The first week, you can treat 3 consecutive days and then once every 3 days.

These examples will give you an idea of the quantities to use according to the size of the animal. Of course, the doses must be adapted whether it is a rabbit, a dog, a sheep or a cow. 

Spraying ALT'O ZINSECT in premises

1 - Shake the can vigorously,

2 - Take a volume of ALT'O ZINSECT spray, dilute it in the same volume of cold, clean water,

3 - Pour the solution into a sprayer, mix well and set the nozzle to fine,

4 - Spray the interior walls of buildings.

For example, the 1 litre can treats 2 boxes, giving them effective protection for 3 weeks.

Insects that disturb the daily life of our animals

As soon as the warm weather arrives and temperatures rise, insects, especially flying ones, can be a real nuisance for the comfort and health of your animals. Horses, cows, donkeys, goats, sheep, pigs and many others are concerned and are regularly harassed. Flies, flat flies, donkey flies, horse flies, ticks, mosquitoes, arabis, simulies come constantly to bother them, sometimes driving them completely crazy. A real ordeal for them.

Lutter contre les insectes piqueurs sur vos poules

Your hen also knows a lot about this. For her, it's not flies but red lice. A real nuisance in hen houses, pigeon houses or aviaries. Whether you are a hobbyist, a small breeder or a professional breeder, whether you keep ornamental birds (canaries, pigeons, serins, parakeets, etc.), laying hens, pheasants or quails, there are few people who have not been infected at least once by this parasite. Through its repeated bites, it causes anaemia (reduction in the number of red blood cells) which can be fatal in young subjects.

Probleme sur vos tetes de flacon. Le vaporisateur fonctionne tres mal. Les tetes se cassent.. cdl


Au top

j'avais déjà testé l'année dernière et là j'en ai repris parce que c'est vraiment efficace. Je l'utilise pour mon ânesse quand on part en balade et j'en mets aussi à mon jeune chien qui adore les fourrés ! Pour mon ânesse je mets aussi le produit en gel entre les pattes et autour des yeux et elle est tranquille (et moi aussi !). C'est vrai que c'est un peu cher mais ça vaut vraiment le coup.

tres bien

bon produit mais tres couteux ce qui est un frein aux achats de ce produit


Au top

C'est la première fois que j'utilise un produit naturel anti-insectes aussi performant pour mon cheval. Une vraie plaie ces insectes sur les beaux jours. Merci à vous.



Enfin un produit qui permet à ma ponette et mon ânesse d'être plus tranquille ! J’utilise en complément le gel pour le tour des yeux et l'entre pattes. En plus le produit sent vraiment bon alors je me dis que ça doit pas trop être gênant pour elles. Et puis pas de produits chimiques de m... dedans ! C'est vrai que c'est un investissement mais je regrette pas vu le résultat !



Pour mes poules difficiles (des Leghorn impossibles à manipuler) dévorées par les poux rouges, une pulvérisation en début de nuit alors qu'elles dormaient : dessus et dessous du croupion, dessous des ailes et cou. Depuis, elles dorment tranquilles. Et moi aussi ! Utilisé en complément du gel, un super investissement : "le prix s'oublie, la qualité reste" !


Polyvalent et efficace !

Utilisé sur chevaux (mouches, tiques) et poules (poux), très facile à utiliser, soulage tout le monde ! merci !
