Make Homemade Insect Repellent for Plants

Insect or bug repellents for plants are readily available in supermarkets or garden shops. But they are not only expensive, they can also cause harm to the plants and to us humans once we inhale them. It is also harmful when we consume those plants, like those in our vegetable gardens. Pests are attracted to our plants. Different insects and bugs, like ants, aphids, mites, and grasshoppers, may frequent our plants and consume from the leaves to the stems and especially their fruits. These insects would eventually kill our plant if they remain untreated. So, if we want to keep our plants in tact, we have our choice of which we want to use -- one of those ready-made insect repellents that are sold in the market and made with harmful chemicals, or a safe and inexpensive homemade spray that we can make in our kitchen. But homemade insect repellents, even if they are known as non-harmful, may still harm our plants if not sprayed properly. Even if we make use of these sprays, we still have to take precautionary measures before we spray them on our plants. We can also make different sprays for different plants, depending on what insect or bug attacks them. We have to know what insects we are dealing with, but some sprays can protect the plants from several insects, so I will be sharing with you several recipes that I make use of and that are really effective.

Tips, Tricks and Warnings

  • Soap can be harmful to some plants. Wash the leaves with water.
  • When oil is sprayed on plants, make sure that the plant will not be directly hit by sunlight.
  • Oil can burn the leaves, stems and flowers of the plants.
  • If the temperature is more than 80 degrees Fahrenheit, do not spray with oil.
  • Take precautionary measures before trying these homemade sprays. Spray on a small portion of the leaf and leave for one day to see if the spray has an unfavorable effect on it, before you spray the entire plant.
  • Discontinue use if you see that it dries out or burns the plant.
  • If it does not burn the plant, you have to continue spraying for several weeks to completely eradicate the insects.
