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

Ready to use produc

This ready-to-use formula contains essential oils and vegetable pyrethrum. It 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.

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

- Vegetable 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.

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 Repellent (formerly named PRO2) 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 two weeks. (The full TEC report is available by clicking here). 

How to use this repellent ?

Spray this repellent 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).

Its composition

Vegetable oil, Essential oils, Active ingredient: Chrysanthemum cinerariaefolium extract produced from open and mature Tanacetum cinerariifolium flowers with supercritical carbon dioxide (CAS: 89997-63-7) 0.025%. Naturally contains allergens: citronellal, citronellol (components of essential oils). 

Choice in packaging

- 500 ml spray bottle

- 1 liter refill container

- Also available in its concentrated form (to be diluted yourself).

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 !

Excellent produit

Généreusement pulvérisé sur mes rideaux et doubles rideaux quand j'aère mon appartement, ce produit à l'odeur citronnée très agréable renforce l'efficacité de mes diffuseurs de répulsifs anti-moustiques (citronnelle, eucalyptus citronné). La possibilité de le recharger est un plus

Efficacité du produit

odeur légèrement désagréable et tenace



A bien fonctionné cet été sur les mouches et moustiques


Répulsif insectes mais pas puces

Nous avons acheté ce produit car il était annoncé comme répulsif pour les puces et en fait pas vraiment. Nous continuons de l'utiliser mais nous ne sommes pas très convaincus par le produit pour les puces
