What is the best homemade insecticide that exists? When we have some plants, the difficult thing is to keep them healthy, without pests, throughout their lives, since they are the food of many insects: some very easy to see, such as grasshoppers, and other smaller ones, such as aphids or red spiders. What’s more, organic treatments can be very effective, but based on my experience, they do not always eliminate the pestespecially if it has already invaded almost the entire plant.
But that doesn’t mean I don’t recommend them: on the contrary. We use more and more chemical insecticides, which are directly responsible for the death of insects that are essential for ecosystems, such as bees or butterflies, and this is a very serious problem, because if we run out of pollinators , many of the plants that we know would stop producing fruits with seeds and would end up becoming extinct. That’s why I’m going to tell you what is the best homemade insecticide and when to use it to be really effective.
Homemade insecticides that work
It is a fact that there are plants that, due to their characteristics, are very attractive to insects, but it is also true that there are others that repel them. An example of the latter is the lavender essence
. This, as you well know, is aromatic. It has an aroma that is very pleasant for us, but it is horrible for a very specific insect: the mosquito. Therefore, we highly recommend plant some lavender for the garden, patio or terrace.
On the other hand, there are also some really curious plants that do not repel insects, but rather the opposite: they deceive them. It is the case of the carnivorous. For example, one of the easiest to care for, the Sarracenia, which develops tube-shaped traps with a kind of hood, produces nectar inside these traps, at the junction between the hood and the rest. In addition, they have very slippery hairs that grow downwards, which means that if an insect loses its balance, it falls into the trap and drowns.
So it is also advisable to have some carnivorous plants, since the Sarracenia are excellent “catchers” of flies, for example, but the Drosera and Pinguicula, on the other hand, catch more tiny flies, such as those of the fruit, and mosquitoes.
But If what you are looking for are homemade insecticides to apply to your plants that already have a pest, I would definitely recommend the following:
- Garlic: Take a head of garlic and crush its cloves. Then, add them to a liter of water, and bring it to a simmer. Once it is boiling, let it cool and then strain it while you fill a bottle or sprayer with the mixture. With this infusion of garlic you can eliminate aphids, but also prevent fungi and bacteria from harming your plant. For me, it is the best homemade insecticide that exists, since even modern medicine has discovered that it has multiple benefits (in this case for humans).
- Copper: I know, you can’t say it’s a homemade product, but it is organic and it’s not hard to find. Copper, like sulfur, are two powerful fungicides that, in fact, are widely used in the preparation of anti-fungal products for use in organic farming. For this reason, it is advisable to apply in seedbeds, but also in plants that have suffered or are suffering from excess water.
- Lemon: you cut a lemon in half, and rub it against the trunk of trees and palms. This is the only way you will prevent them from being filled with ants. But if you have any with flying insects (whitefly, aphids, etc.), boil 1 liter of water and add the lemon peel. The next day, strain it and fill a spray bottle with this mixture. So you can apply it to plants.
- Diatomaceous earth: It is a product that when you see it for the first time, it gives you the impression that it is a type of flour. But nothing is further from reality: it is composed of fossilized algae, which contain silica. Silica is what causes practically any insect -small- to die of dehydration, since it perforates its body. Of course, when applying it, wear gloves because, although it is not toxic, if you have sensitive or dry skin like me you may feel some itching (it goes away immediately with water). It will help you eliminate aphids, mealybugs, whitefly, red spider, etc. you can buy it here!.
Although there are many more Home RemediesTo date, the ones that have worked best for me are these four.
So which one is the best?
It depends on the problem that your plant has, but I am convinced that one of the ecological insecticides that eliminates the most pests is diatomaceous earth. It takes a few days to take effect, yes, but since it leaves no residue and, in addition, it serves as a fertilizer for the land, its use is very interesting. You can apply it at any time, and in a short time you will see how the plague disappears.
Here is a video in which we talk about this product:
When to apply homemade insecticides?
The problem with many homemade insecticides is that they are very useful as preventiveor when the plague is not yet very advanced, such is the case of potassium soap or tobacco infusion. Others, like the diatomaceous earth, they do serve more as curatives, since their effectiveness is greater and they can kill it.
Therefore, it is important to know when to apply these homemade products so that they really serve us. Y, when is that? As soon as we notice the first symptoms. The first. In other words, we don’t have to wait for the leaves to turn wilted or for pests to invade them. What are those symptoms?
- Some spots appear on the leaves
- We begin to see some insect on the underside of them and/or on the tender stems
- Some sheets appear folded or closed
But if the situation of the plant has worsened a lot, then it must be treated with diatomaceous earth.cleaning its leaves with water and neutral soap beforehand so that the product takes effect faster.
We hope it has been useful to you.
