If you’re a plant enthusiast, whether indoors or on your terrace, you’re well aware of the importance of keeping insects at bay. These pests can ruthlessly attack your plants, hindering their growth or even causing them to wither away. Here’s a simple guide on how to prepare a homemade spray – one of the most powerful (and eco-friendly) natural insecticides for the protection and maintenance of your beloved plants.


  • 25 ml neutral soap
  • 50 ml white vinegar or apple cider vinegar
  • 1-liter pitcher
  • Spray bottle


  1. Fill the pitcher with 1 liter of water.
  2. Add 25 ml of neutral soap (dish soap, for example) to the water, and mix thoroughly.
  3. Slowly pour in the vinegar while continuing to stir, preventing the soap from foaming.
  4. Transfer the solution into the spray bottle.

Remember to apply the DIY insecticide in the evening or on cloudy days. Doing it under direct sunlight could potentially harm the plants.

Spray the solution all over the plant, including the leaves and stem. Let it sit for 15 minutes, then rinse the plant with a bit of water.

If you notice lingering insects, wait for two or three days and reapply the DIY insecticide. To keep your plants insect-free, apply a small amount of the solution once a week.
