How to Prepare It
- In a large container, pour 1 liter of water.
- Add the liquid soap and stir gently to avoid too much foam.
- Mix in the vegetable oil, which creates a coating that suffocates soft-bodied insects.
- (Optional) Crush garlic or chili peppers, let them steep in warm water for 12 hours, then strain and add to the mix.
- Pour the solution into a spray bottle.
How to Use It
- Spray directly on the leaves, stems, and undersides of plants, where pests hide.
- Apply in the early morning or late afternoon to avoid leaf burn from sunlight.
- Repeat every 3–5 days until pests disappear.
- Use preventively once a week during growing season.
Extra Tips for Success
- Rotate ingredients: Sometimes alternate between garlic spray, chili spray, and soap spray to avoid pests developing resistance.
- Target soft-bodied insects: This works especially well on aphids, whiteflies, mealybugs, and spider mites.
- Combine with companion planting: Planting basil, marigolds, or mint nearby naturally repels insects.
