1) Diatomaceous earth, one of the best natural insecticides
Its 80% mineral silica has a powerful short-term effect for all those who want to find a radical solution against small beasts. Indeed, this formidable powder saves your plants by dehydrating all insects (especially against the very invasive ants). This organic insecticide also has a preventive and repulsive effect, especially on snails. Thus, you can spread it around and on the plants, on the foliage. On the other hand, water inactivates it a little, so don’t hesitate to reapply it as needed after a rain shower.
2) A few sprays of garlic spray will work very well as a natural insecticide
Can’t see yourself making a meal without garnishing it with a little bit of candied garlic? Unfortunately for them, its active ingredients and distinctive smell allow it to fight the worst infestations. To create a ready-to-use curative for the garden, puree two garlic bulbs (not just the heads). Then mix this paste with 250 ml of water and leave overnight to concentrate the infusion. Then add half a cup of vegetable oil and a teaspoon of liquid soap or dishwashing liquid. Then dilute in a spray bottle of water and treat the infested plants. No need to rinse when you have finished treating the crops and eliminating the pests.
3) Natural treatment in the form of a soap spray
Gardeners can make smart use of organic black or liquid soap to control garden mites, moths, beetles, aphids or even white flies in the vegetable garden. To make this mixture to spray on infested leaves, you will need to incorporate 1 and a half tablespoons of mild liquid soap in 250 ml of water. However, avoid doing it in full sunlight or you will burn the plants! Instead, do it early in the morning or in the evening.
4) Natural oil-based insecticides
They suppress insects by covering their bodies with oil and suffocating them. Here, it is possible to use a cup of vegetable oil such as rapeseed oil or any cooking oil. Then, a tablespoon of soap will be added to it. Then, before spraying it, we will take 2 teaspoons of the preparation to dilute it 250 ml of water. As simple as that!
Otherwise, it is possible to use neem oil (neem tree). It is one of the most powerful natural insecticides with a range of action covering more than 400 species of insect pests sometimes resistant to chemical pesticides and works equally well on adult specimens as eggs and larvae! Indeed, its hormones prevent insects from feeding by disrupting their nervous system. Also, this preventive and treating fungicide is biodegradable and presents no toxic danger to domestic or wild animals. To use, mix 2 teaspoons with 1 teaspoon of liquid soap and 250 ml of water.
5) The spicy formulation treatment
Fresh or powdered chili pepper works just as well as garlic to kill bugs and grubs. Before you can spray it, you’ll need to mix it with a little liquid soap and 250 ml of water. To measure out the chili pepper, use one tablespoon of powder. The dosage would be more like a half in a cup of water for a fresh chili pepper. In addition, note that it is better to take your precautions not to irritate your skin or your mucous membranes. So, avoid irritation by wearing gloves and being careful with your mouth and eyes when spraying.
6) The all-in-one lightning spray that mixes the natural insecticides presented above
For this mixture, you’ll need to bring along: 1 small onion and 1 garlic bulb crushed and 1 teaspoon of cayenne pepper powder. Mix everything together and leave for an hour before filtering carefully and adding 1 tablespoon of liquid soap. Dilute in a good amount of water and spray this powerful solution on both sides of the affected leaves. Between uses, remember to put this product in the fridge!
7) And finally, tomato leaves are also good natural insecticides
Some of their molecules, alkaloids, are effective against insect invasions, especially aphids. Put a large handful in 250 ml of water and let it infuse overnight. After filtering, you can spray your little 100% natural preparation! By the way, note that you can also use them against unwanted flies, especially at mealtime. It’s not well known, but always good to know 😉
