Neem oil works by disrupting the insect’s hormones and preventing them from feeding and reproducing. It can also coat the insect’s body and suffocate it. It is most effective against the immature stages of insects, but it can also kill adults.

How to Use Neem Oil

Neem oil can be applied as a foliar spray or as a soil drench.

  1. Mix neem oil concentrate with water and mild liquid soap according to the label directions.
  2. Pour the mixture into a spray bottle and shake well.
  3. Spray the entire plant, including the tops and bottoms of the leaves, stems, and soil.
  4. Reapply the spray every 7-10 days until the pests are gone.

As a soil drench:

  1. Mix the oil concentrate with water according to the label directions.
  2. Pour the mixture around the base of the plant.
  3. Reapply the soil drench every 2-3 weeks to prevent pests and diseases.

There are also ready-to-use mixes available that you simply spray right from the bottle. Be sure to read the directions to find which method is right for you.

  • Do not use in direct sunlight.
  • Test on a small area of the plant before using the spray on the entire plant.
  • Reapply regularly to maintain its effectiveness.
