What is diatomaceous earth ?

Diatomaceous earth is a natural product often used for pest control and environmental protection. It is a substance formed from diatoms, fossilised microscopic algae rich in silica. Its texture resembles that of a fine, light, white powder, and it is completely safe for humans and animals, making it an attractive option for domestic use.


Diatomaceous earth, a natural insecticide

Diatomaceous earth has formidable drying, dehydrating and abrasive properties for insects and other parasites. The microscopic particles cut through the protective waxy layer of their exoskeleton, causing them to dehydrate and eventually die. This mechanism of action makes it an effective solution and an excellent natural insecticide for getting rid of harmful insects such as cockroaches, ants, fleas, bedbugs and mites.

Crawling insects are particularly affected because once they have passed through this diatomaceous earth, the after-effects are irreversible. This is never immediate (24 to 72 hours), but always fatal for the insect affected. You will understand that diatomaceous earth has a more limited effect on flying insects.

Diatomaceous earth can be applied to plants to control pests such as slugs, snails, aphids and caterpillars. By depositing a thin layer of diatomaceous earth on the leaves and stems of plants, it acts as a physical barrier to repel insects. It is also effective in protecting stored grain from insects and rodents.

Diatomaceous earth is a versatile natural product that offers a safe and effective alternative to chemical insecticides. Its ability to combat pests while preserving the environment makes it a valuable ally in pest control, whether inside the home or in the garden. By using it responsibly, we can protect our living spaces while respecting the biodiversity that surrounds us.


Diatomaceous earth, for which insects ?

Diatomaceous earth can be used against a wide range of insects: Ants, aphids, mites, cockroaches, moths, maize earworms, earwigs, flies, leafhoppers, bedbugs, dimorph estigmata, weevils, spider mites, carpet beetles, millipedes, silverfish, slugs, mites, lice, red lice, snails, bedbugs, red spiders, floor fleas ...

Ideal against crawling insects

Terre de diatomée Aries

Insectosec® powder is composed of a powder of fossilized marine micro-algae: Kieselguhr (otherwise called diatomaceous earth). No transformation was made to arrive at the finished product. This diatom is thus extracted directly from quarries.

This insecticidal powder acts by contact. Its fine crystalline structure causes lesions on the chitin (main component of the cuticle of insects and certain larvae), leading to their dehydration after 2 to 3 days.

This insecticide has a mechanical action and will be particularly effective in controlling crawling insects. It is odorless, can be used both indoors and outdoors (however, beware of showers and ambient humidity).

This diatom will be effective against

This insecticidal powder is effective against most crawling insects such as fleas, bed bugs, spiders, cockroaches, red lice, beetles, ants... The list can be long... In fact, all crawling insects are concerned.

Benefits of this Insectosec® diatomaceous earth

+ Long-term protection of treated areas,
+ Effective natural insecticide against all crawling insects
+ Odorless and unprocessed
+ 100% natural and ecological certified Organic Farming
+ a product authorized and classified biocide TP18 (insecticide powder)
+ Harmless to pets

How does this diatomaceous earth work ?

Insects such as red lice (strongly present in poultry farms), but also crawlers: woodlice, ants, etc. are covered with powder or are sprinkled during application.

The substance acts on the outer protective layer of the insects, causing them to dry out and then die after a few hours.

Tip : Diatomaceous earth is very effective against bed bugs: surround the legs of the bed with diatomaceous earth, also sprinkle the area between the mattress and the box spring. For maximum effectiveness, also dust carpets, bedroom corners and around furniture legs.

How to use this diatomaceous earth ?

Put powder on the places of passage and the hiding places of the pests. Use this product indoors (baseboards, cracks, bed legs, animal sleeping areas) and outdoors (patios, pool slabs). Apply 5 g/m² (i.e. a strip 0.5 to 2 cm wide by 2 mm high) around the areas to be protected. Re-apply diatomaceous earth monthly if needed. Do not use in rainy weather. At low temperatures or when the air is humid, the effect of Insectosec® may be delayed by 1 to 2 days.

Duration of action

The application is to be repeated after dispersion of the spilled powder. Monthly if needed or when powder is too wet.

Active substance

Silicium Dioxide/Kieselguhr* (CAS No. 61790-53-2): 100% Diatomaceous Earth. TP 18 - Insecticidal powder

*Silicium Dioxide/Kieselguhr is composed of sharp algae fossils, (also called Diatomaceous Earth), an amorphous (non-crystalline) form of silica that occurs in nature.

A product classified TP 18 insecticide

This Insectosec® diatomaceous earth from the Aries brand has obtained marketing authorization for biocides (AMM). This authorization is issued by the competent authorities, following the scientific evaluation of the efficacy and the risks of the biocidal product linked to its use. Today, thanks to this MA, Aries guarantees that the diatomaceous earth used in their product is effective on all crawling insects because these tests were carried out on the cockroach: the most resistant insect. The procedure for obtaining an MA is very long and costly, which obviously has repercussions on the price per kilo of the active substance. Hence a significant price difference per kilo between this diatom classified as biocidal and a non-biocidal diatom.


100 g bottle with spout.

Très efficace

j'avais déjà utilisé pour éradiquer des poissons d'argent il y a deux ans. Depuis je continue à en mettre par prévention


Combat contre les poissons d'argent

a priori efficace. J'ai retrouvé des poissons d'argent asphyxiés dans les WC et la cuisine. Le seul souci est que je ne peux pas en mettre dans les endroits fréquencés par les animaux.
Je ne peux pas non plus en mettre dans les VMC, la poudre serait rediffusée dans l'air et inhalée.
J'espère vite en venir à bout. La présence de ces bestioles me hante.


Poudre insecticide rampants - Terre de diatomée

J'en suis super contente. Je l'ai utilisé dans ma caravane infestée de perce oreilles et de fourmis. Plus rien !

Helène H


La terre de diatomée reste un moyen de lutte vraiment efficace sur beaucoup d'insecte. Je ne peux que la recommander

Véronique L


On saupoudre et on trouve les indésirables morts... sans oublier qu'il n'y a aucun produit chimique ! Le top, je recommande ++++

L. Ryati

Je le recommande à mon entourage.

Je l'utilise surtout contre les poissons d'argent. J 'en ai soupoudré dans les endroits habituellement propices. Pour le moment, rien à signaler. Je suis soulagée. Merci.

Merci d'avoir laissé votre avis qui servira à de nombreuses personnes.
Effectivement la poudre insecticide rampants n'est pas préconisée pour le traitement des acariens. Pour cela, vous pouvez utiliser par exemple l'aérosol anti-acariens Ecodoo.
La poudre Ariès n'est pas à utiliser sur vos animaux de compagnie, mais seulement sur leur lieu de couchage. Une fois que le traitement a été efficace, vous pouvez aspirer soigneusement les lieux si vos animaux sont sensibles. Les personnes sensibles, quant à elles, peuvent porter un masque (pour ne pas respirer les particules fines de la terre de diatomée) et des gants (pour éviter le contact avec la peau) lors de l'application.
Enfin, n'hésitez pas à consultez la fiche de données de sécurité, dans laquelle vous pourrez constater que ce produit n'est pas reconnu comme allergène. Mais nous le disons souvent, ce n'est pas parce qu'un produit est naturel, qu'il est innofensif et que l'on ne doit pas respecter certaines précautions lors de son application.
A bientôt

Pas si recommandable que ça.

Efficace contre quelques insectes
rampants ainsi que pour les puces, pas contre les acariens. Très allergène, dessèche la peau et les poils et les rend rêches et cassants, provoque des démangeaisons chez les animaux et les humains sensibles (yeux rouges, démangeaisons cutanées, asthme.
