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.

Effective snake repellent

Repousser les serpents naturellement avec notre répulsif serpents

When the warm weather arrives, it is common for our leisure time to be disturbed by snakes in the open air. They like shelters and hiding places of all kinds such as tall grass, stones, debris, tiles, rocks, tarpaulins, or even piles of various materials such as piles of wood or logs... You can therefore come face to face with a snake during a picnic near a river, or in the vicinity of your home such as the terrace or the pond...

If some people are downright phobic about them, their presence does not reassure most of the time. However, snakes are essential to our ecosystem. In particular, they regulate the population of rodents (mice, field mice, etc.), insects (flies, mosquitoes, bugs, cockroaches, etc.) and larvae. They can also prevent a garden from having its vegetable garden and plants destroyed by the small insects that devour them. The idea is not to eliminate them, you would be punished because snakes are protected species (law of 1976 which protects all the snakes of the territory).

The solution to not being disturbed by their presence is to put in place a solution that will repel them and keep them away from places where they are unwanted.

Made from cereals, margosa extract and vegetable oil, ALT'O SNAKES is a highly concentrated natural repellent that will effectively keep all snakes away from places where their presence is undesirable.

The use of ALT'O SNAKES is very simple since it is enough to create a barrier by spreading a line of granules around the zone which you wish to protect.

This anti-snake product is perfectly suited to protect your home, garage, garden, orchard, terrace, but also the edges of ponds or swimming pools, rock gardens, playgrounds, picnic areas, camping areas, and anywhere else where the presence of venomous or harmless snakes is not desired.

How does ALT'O SNAKES work ?

As you may know, the snake has a very powerful olfactory organ which it uses to decode the odorous molecules taken from the air by its bifid tongue. This organ is called the Jacobson's organ. Thanks to their forked tongue, they "collect" substances in the air. This information is transferred to the palate and then transmitted to the brain by means of the Jacobson's organ located behind the vomer, between the nostrils and the mouth. But in addition to the 'decoding' of this chemical data by the vomeronasal organ, a large proportion of snakes can also recognise the heat emitted by warm-blooded animals. Located in front of their nasal cavity, this information detector is used to find potential prey but also to recognise their family members.

Alt'O Snakes are composed of strongly odorous substances that are unpleasant for them, and they will immediately move away from them, preferring to go to a space where this odour does not exist. The reptile's escape is therefore guaranteed. Alt'O Snakes acts on the reptile's sensory receptors and acts as an excellent barrier.

Directions for use

Scatter the granules over the whole area to be protected to scare away snakes.

After 48 hours, make a 10 to 20 cm wide band around the area to be protected.

In order to have a good protection, plan at least 4 grams of snake repellent per linear meter, i.e. 400 grs for 100 ml. With this dosage, tests have shown that the area can be protected for 3 weeks (see tests)

Despite a rigorous treatment and good vigilance, a snake can emerge from the ground, for example, by passing through a field mouse gallery. It is therefore very important to remain vigilant by scattering a few granules on the surface of the area from time to time. In order to preserve the properties of this repellent, our cans are treated "anti-migration". It is therefore necessary to keep the product in its original container.

Un répulsif qui me semble bien faire son travail. La couleuvre que j'observais dans ma rocaille à déménagée. C'est donc bon signe !


répulsif serpent.

bien reçu j'en ais mis a plusieurs endroit et pour l'instant je n'ai revu aucune couleuvre. ça a l'air de marcher mais un peu tôt pour le dire on verrat l'année prochaine.

les serpents n'ont clairement pas appréciés l'odeur (moi non plus d'ailleurs). Ce qui les a fait fuir très vite. Donc au final, plutôt satisfait de cet anti-serpent naturel.


un peu decu !!

les lézards ont disparus quelques jours avant de revenir comme avant
