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.

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 of this gel

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 gel on the animal

Apply ALT'O ZINSECT gel with a soft brush or by hand to the hairless parts of the animal: sheath, anus, vulva, teats, inside of the ears, corners of the mouth, nostrils, flank, base of the neck, possibly up to mid-flank.

Be careful around the eyes. Leave at least 5 cm between the gel and the edge of the eyelids.

Apply 10 to 15 ml per spot (10 ml = 2 teaspoons; 15 ml = 1 tablespoon). Causes the parasites to disappear. This product is of course interesting for treating certain delicate parts of the body, but also for all animals that do not tolerate sprays! It will also be useful when the farrier changes the shoes, so that the horse is not irritated by the flies. 

In periods of heavy attack and for optimum protection, apply ALT'O ZINSECT Spray once or twice a week to the animal's coat.

Application of ALT'O ZINSECT gel on supports or equipment

Harnesses, halters, feeders, nesting boxes, cages, etc. are supports or equipment located close to the animal. You can use ALT'O ZINSECT gel by applying it directly to these supports to protect the animal from insects. 

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.

Excellent produit

Il semblerait que ce produit marche à merveille et en plus il ne sent pas trop fort donc ne dérange pas trop mon cheval. Je l'utilise surtout pour éviter que les tiques ne viennent se loger sous sa tête et à l'intérieur de ses membres. Je recommande.



Parfait pour protéger le contour des yeux et entre les pattes de mon ânesse. J'utilise en complément la version spray et tout le monde est tranquille! Je préfère payer un peu plus cher mais avoir un produit vraiment efficace comme celui-ci.

Marche plutôt bien

J’utilise le gel pour mes 3 chèvres laitières. Les mouches et moustiques se calment pendant 3 jours, après il faut en remettre. Cette année j’en ai utilisé tardivement et mes chèvres ont attrapé des myases, alors que l’année dernière j’avais protégé plus tôt et n’en avais pas eu, je ne sais pas si c'est lié. Mes chèvres adorent se faire crémer. Un petit bémol sur le prix car le pot part vite!

Pratique et efficace

Produit facile à appliquer et efficace sur les parties sensibles des poneys.



pas top comme produit mais comme tous les produits pour chebvaux il faut en passer toutes les heures !!!!!


Vraiment interressant

Satisfait de ce produit. Facile à appliquer et une très belle action répulsive sur les insectes piqueurs



Je suis partie avec un âne cet été en randonnée. J'en ai appliqué régulièrement au fil de la journée. ça a été très efficace pour moi ... et surtout pour mon compagnon de route !


Miraculeux !

Dès la 1ère application sur la paroi du poulailler, les poux rouges cachés se sont retrouvés englués. Appliqué également sous les perchoirs avec le même succès. Les poules sont soulagées. Je suis ENCHANTÉE par ce produit : odeur forte mais agréable qui ne gêne pas les poules. Compliqué à nettoyer (surtout quand il y a des milliards de poux collés) mais le jeu en vaut la chandelle : plus de poux après 2-3 jours de traitement.

Gel anti poux-rouges

Efficacité 1000% pour le gel anti poux rouges ! Ces saletés se sont engluées dans le gel dès la première nuit. Merci et bravo !


Au top !

Très efficace comme son compère en spray, la formule gel permet en plus une application précise sur les zones sensibles, comme le tour des yeux etc pour les chevaux par exemple ! et transportable facilement en petit flacon. Merci à vous !
