How to make a natural pesticide: the expired milk method

One teaspoon is enough to protect your plants naturally and economically.

Having the yard full of   plants   and flowers is definitely a wish for anyone with green thumb.

To have   healthy  and lush plants, however, there are many aspects to take into account and to which we pay all our attention. One of them is the possible attack of   parasites  . Insects (and not only that) that   attack   plants to feed them and in doing so weaken them.

If you have noticed the presence of these annoying “plant enemies”, don’t worry. There are several specific products on the market, but they are mostly industrial products.

Instead, you can use   common ingredients  that you probably have at home. Have you ever had a bottle of   milk   in the refrigerator for several days after the   expiration date  ? Don’t throw it away, because it’s good for you.

Let’s see how.


  • 500 ml of expired milk
  • 1 teaspoon garlic powder
  • Gauze or cotton canvas.
  • Funnel
  • Spray


  1. Mix milk and a teaspoon of garlic powder.
  2. Mix well and leave for 2 or 3 hours.
  3. Strain the mixture through cheesecloth and place it in a spray container.
  4. Bathe the plant regularly: this will protect it from parasites.
