• 10 ml (2 tsp) of organic neem oil or an oil maceration of neem leaves or powder (Omit if using on outdoor plants!)
• 15 drops of organic clove essential oil (Eugenia caryophyllus) (optional)*
• 15 drops of organic bay laurel essential oil (Laurus nobilis) (optional)*
• 450 ml of water
• 5 ml (1 tsp) of unscented Castile soap **
• 500 ml amber spray bottle

*You can opt for other insecticidal and insect-repelling essential oils: field mint, spike lavender or rose geranium, alone or blended. You simply have to respect the total amount, which is 30 drops.

** A bonus tip! You can use our Castile soap like black soap for caring for your plants. Just dilute 1 tbsp of Castile soap in 1 cup of boiled, then cooled water.

1. Pour the neem oil into the bottle and add the essential oils, if desired.

2. Mix gently to help the oils dissolve in the oil.

3. Add the water, then the Castile soap.

4. Close the bottle and shake well.

Parasitic insects can affect the health of our plants by munching on them with gusto, can pass diseases to them, and risk spreading from one plant to another and becoming hard to eradicate. Oh no, not that!

That's why we must inspect our plants regularly, isolate those that are affected and treat them properly if we notice little unwanted guests. Good thing you now have your “natural born killer” insecticide!

Mix the insecticide before each use and spray directly on the leaves (top and underside), stems and soil of affected plants, including less visible parts.

Repeat every 4-5 days, as needed.

Warning: we avoid using this insecticide outdoors, since neem oil also affects beneficial pollinating insects, which we definitely don't want. So you can omit it for outdoor use.
