Organic insecticide against caterpillars (Bacillus thuringiensis)

This organic treatment against caterpillars contains a natural microorganism: Bacillus thuringiensis, also known as BTK. It acts specifically on plant-eating caterpillars, including the box tree moth and the processionary caterpillar. After ingestion, the larvae stop feeding and are eliminated within a few days. It is a perfectly selective biological insecticide, respectful of the environment, beneficial insects (bees, ladybirds), animals, and humans.

It is used in particular on vegetables, fruit trees, ornamental shrubs, and potted plants. Thanks to its targeted action, it helps effectively control fruit worms, the box tree moth, or caterpillars that attack your flower and vegetable crops.

🌿 How to use Bacillus thuringiensis insecticide?

  • Pre-harvest interval: 5 days
  • Dosage: 1 g/L of water
  • Dilute the dose in a little water, shake, then top up the sprayer
  • Thoroughly wet both sides of the leaves – an even spray is essential
  • Shake the mixture regularly during treatment

💡 A measuring scoop is included in the box (about 4 g)

📆 When to apply this biological treatment?

Act as soon as larvae appear or preventively during high-risk periods. Bacillus thuringiensis is a contact and ingestion insecticide: it is important to treat at the first signs of damage for maximum effectiveness.

💡 Gardener’s tip / trick

To effectively fight the box tree moth 🐛 or the processionary caterpillar, regularly monitor your plants from spring onwards. Early treatment with Bacillus thuringiensis quickly limits the infestation. Don’t wait until the leaves are completely eaten! Repeat the treatment in case of a new generation or after heavy rain.

Oui. Le Bacillus thuringiensis (BTK) est homologué contre les chenilles phytophages, dont la pyrale du buis. Pour un bon résultat, traitez dès l'apparition des premières larves au printemps (mars-avril), en pulvérisant les deux faces des feuilles. Les larves âgées ou les infestations avancées nécessitent plusieurs applications.

Après ingestion du traitement, les chenilles cessent de se nourrir en 1 à 3 jours et disparaissent progressivement. Les dégâts visibles sur les feuilles n'ont pas le temps de se résorber, mais l'attaque s'arrête. Si de nouvelles chenilles apparaissent (nouvelle génération), renouveler le traitement.

Oui. Ce traitement est homologué sur tomates et aubergines. Le délai avant récolte est de 5 jours après la dernière application. Il est conseillé de traiter en soirée et d'attendre que le feuillage soit sec avant de manipuler les plantes.

Oui. Le BTK est dégradé par les UV et lessivé par la pluie. Si de fortes pluies surviennent dans les heures suivant l'application, renouveler le traitement. Par temps sec, l'efficacité sur les feuilles dure plusieurs jours.

Le BTK est une bactérie naturelle qui n'agit que sur les chenilles phytophages. Il ne touche pas les insectes utiles (abeilles, coccinelles), les vertébrés, ni les autres insectes. Un insecticide chimique à large spectre peut détruire d'autres organismes. Ce produit est homologué (N° AMM 2150417) et respecte la réglementation française pour les jardins.
