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.

A 100% plant-based insect repellent

This formula concentrated in essential oils and plant pyrethrum is particularly effective against flying insects and mainly against flies and mosquitoes.

Unlike most insect repellents on the market, our product does not contain DEET or Pyrethroids, or any product of synthetic origin. Due to its composition, this repellent can be used everywhere without danger, under normal conditions of use, for humans, animals and the environment.

It is a concentrated product that you will need to dilute with water before use.

In order to make this repellent, we mainly used 2 products known for their repellent properties.

- Pyrethrum which has a repellent action on practically all insects.

- Some essential oils such as geranium, lavandin or lemongrass whose repellent properties are well known. In order to increase the persistence of these products over time, they are diluted in vegetable oil.

Range of action

The repellent action radius of this product is limited, so, as with all commercial repellents (organic or synthetic), do not expect to prevent insects from entering through a 6 m² bay window by only treating the management !

A lab-tested repellent

This product has been tested by the independent laboratory TEC.

Conclusion of the test carried out by the TEC laboratory :

Penn'Ty Bio insect repellent showed a highly significant intrinsic repellent effect (94%) against flies and 98% against mosquitoes when applied directly to the inert surface as well as a residual repellent effect of two weeks. (The full TEC report is available by clicking here). 

How to use this concentrated repellent

We recommend a 20% dilution. You can decrease or increase this concentration depending on the applications. Mopping the floors with the diluted product is also another protection solution against insects.

Diluted at 20% in water, this concentrated 250 ml bottle allows you to make 1.25 liters of repellent (1 bottle of 250 ml of repellent in 1 liter of water) and to cover an area of 12 to 15 m² (according to insistence in the application).

After diluting this product in the desired concentration, spray it on all fabrics such as curtains, tents, mosquito nets, net curtains or on all non-absorbent surfaces (paint, tiles, etc.) such as the floor, shutters, door frames, windows, etc... Being rapidly biodegradable, avoid sunny surfaces.

As insects will avoid all treated surfaces, the more treated surfaces you have, the more you will increase your protection volume.

Review Penn'Ty Bio

Our results confirm the tests carried out by the TEC laboratory. No insects and mainly flies have landed on the treated surfaces for at least 10 days (be careful in laboratory test conditions, the persistence will obviously be shorter for an application of the product outdoors or any prolonged exposure to UV, heat and rains).

Réponse de Penn'Ty Bio

Bonjour Christian,
Nous sommes désolé que ce produit ne vous donne satisfaction.
C'est la première fois que nous avons une telle remontée avec ce répulsif. Il est pourtant à notre catalogue depuis de nombreuses années et a donné satisfaction à de nombreux clients.
Si le dosage à 20% a bien été respecté, n'avez-vous pas trop insister sur la quantité pulvérisée sur les supports cités ? La description des traces tenaces que vous décrivez nous laisse penser qu'une quantité trop importante a été appliquée. Ce répulsif contient notamment une huile végétale pour augmenter la rémanence et l'efficacité de l'action du pyrèthre. Lors de l'application, il est important de ne pas insister trop longtemps sur la pulvérisation pour éviter les effets indésirables que vous décrivez. Un simple passage, sans aller-retour suffit à créer un dépôt du produit en surface et créer une barrière suffisante contre les insectes volants.
Pour les rideaux, un passage en machine à laver permettra d'éliminer les surplus de résidus. Pour les autres supports, un dégraissant comme un liquide vaisselle et une éponge humide élimineront sans difficulté la pellicule grasse déposée.
Penn'Ty Bio



Produit qui tache es rideaux, les pas de porte, les vitres . Très difficile de nettoyer les vitres car produit gras. La notice fausse, indique «  diluer à 20% », dans ce cas impossible d’utiliser le pulvérisateur, Trés décevant. Et beaucoup d’huile de coude à prévoir pour enlever ces traces de gras.



appliqué sur des encadrements de fenêtres. A bien réagit face aux insectes volants. Je les observaient après l'application et on voyait bien que ça les perturbait. Ne pas hesitez à réappliquer de temps en temps, surtout l'été quand l'exposition au soleil est forte



Répulsif efficace

Sabine M


Satisfait de ce produit concentré. Pratique. ça me permet de faire moi même ma préparation (et ma concentration)

Raymond R.


Idem, je suis satisfait de ce produit. L'effet répulsif est bien là. Il ne faut effectivement pas s'attendre à éloigner les insectes de toute son habitation. Son champ d'action est efficace au niveau des surfaces que l'on traite et dans un rayon d'environ 40 cm. ça me suffit. Difficile d'avoir mieux avec des composés 100% naturel.

Yvon U


J'ai trouvé pour ma part ce produit efficace. Il tient à distance des surfaces traitées les insectes. C'est ce que je souhaitais.



Ce répulsif n'est pas éfficace chez moi non plus, mais il sens très bon

Réponse de Penn'Ty Bio

merci d'avoir pris le temps de nous faire part de votre impression. Nous sommes navrés que ce produit ne parvienne pas à vous satisfaire. Peut-être que celui-ci n'est pas adapté à votre utilisation.
L'efficacité de ce produit a été confirmée par des tests officiels réalisés par le laboratoire TEC (visible sur notre site). Mais comme tout répulsif, son champ d'action est limité aux surfaces traitées.
Nous restons à votre écoute.
A bientôt.
Penn'Ty Bio.



ce produit n a pas été efficace chez moi. Dommage !!!
