What you need

Here are some recipes:

Based on black soap:

  • The base: dilute 5 tablespoons of liquid black soap with olive oil in 1 liter of lukewarm water. Once the preparation has cooled, spray on the leaves and stems, preferably in the morning or at the end of the day. Don’t forget the underside of the leaves. Repeat the operation several days in a row if necessary.
  • Bicarbonate fungicide treatment: In 1 liter of hot water, dilute 2 teaspoons of bicarbonate and 1 teaspoon of black soap. Once the preparation has cooled, spray on the leaves and stems, preferably in the morning or at the end of the day. Don’t forget the underside of the leaves.

Based on Marseille soap:

  • Dilute 20 grams of Marseille soap in shavings in 1 liter of hot water. Once the preparation has cooled, spray on the leaves and stems, preferably in the morning or at the end of the day. Don’t forget the underside of the leaves. Repeat the operation several days in a row if necessary.

Based on Castile soap:

  • Add 1 tablespoon of liquid castile soap to a 750ml spray bottle filled with hot water. Shake vigorously to mix.

*Optional: you can add 1 tablespoon of vegetable oil to help the mixture stick to your plants. Spray this mixture generously on your plants, starting at the base but without neglecting the leaves and flowers. Stink bugs hide in crevices and the undersides of leaves, so be thorough.
