Organic Pest Controls

Organic Pest Controls

Biological methods of pest control, as a rule, are less harmful to the environment and toxic. Wherever possible, you should first use the least toxic method. There are very effective natural methods of pest control. The good news is that with proper education and cultural practices, they rarely, if ever, need to go beyond the initial levels of protection.

The first step in pest control is to create the most favorable environment for the growth of your plants. A healthy garden is the best of existing organic pesticides. This creates biodiversity. Therefore, useful insects, without the need to apply any treatments, can treat pests for them.

Although useful insects are incredibly effective, you probably need to show some tolerance to some pest damage. Organic methods are usually not as fast, but over time they can become as effective as synthetic means of struggle.

With any antiparasitic treatment, the first step is to identify the intruder and select a method of struggle that will act only on him. You do not want to use a selective chemical that can also damage useful insects!

There are quite a lot of biological variants, and some are more specific to certain pests than others. Here are some of the most popular options in order from the least toxic to the most toxic.

Microbial insecticides

These insecticides cause pest health issue, are very specific for target pests, do not harm beneficial insects and are not toxic to mammals. One of the most popular options is Bt (Bacillus thuringiensis). I use it whenever necessary to treat a range of worm larvae, from hornworms to cabbage roots and tapeworms. The Bt bacterium paralyzes the digestive system of the larvae, and within a few days the parasites die. If there is one drawback to this type of insecticide, it is that it does not act as quickly as you would like, but it is very effective and worth the compromise.

Insecticidal oils

These oils work by suppressing pests. The oil envelops them with an oil-based liquid and blocks their access to oxygen. This method of struggle has existed for a long time. It is mainly used to finish eggs and immature stages of insect development. These foods are very effective because they are well distributed and quickly broken down. However, these oils can affect beneficial insects, but they are less toxic to them.

Oils are often used to action aphids, thyroid glands, spider mites, powdery mildew, psylla and some other insects. These oils can damage your plants and trees, mainly leaves. Therefore, be sure to read the instructions that accompany the packaging.

Never spray these oils on a hot day, usually above 85 degrees, and it’s best to spray a small portion of your plants first. After a few days, check if the oil is damaged before starting to apply a larger volume. If no damage is detected, continue spraying, covering the upper and lower surfaces of all leaves.

Land of diatoms

This product is a petrified siliceous algae shell. Although these shells are microscopic in size, they are covered with sharp protrusions that cut through the cuticle of the insect and penetrate into it. This leads to leakage of vital body fluids of the pest. The result is dehydration and passed away. The uniqueness of diatomaceous earth is that the cause of the damage is not the coarseness, but the abrasion resistance of the dust for the body.

DE is effective against soft pests, including aphids, flies, whitefly, caterpillars, root larvae, slugs and snails. However, DE is not selective and can also damage beneficial insects. Apply to the soil to action pests that live on the soil, and to the foliage to action other pests. Therefore, for better adhesion to damp foliage, it is best to apply it in the early morning, when the leaves are wet from dew or after rain. Be sure to use “natural quality” compared to “pool quality”. It contains additional chemicals that can be harmful to humans and mammals when inhaled. In both matters, it is recommended to put on a respirator when working with a dust remover.

Insecticidal soap

The salts and fatty acids contained in this soap are used to action many soft pests, including aphids, whitefly, thyroid glands, earwigs, thrips and lepidoptera. Insecticidal soaps penetrate the soft outer shell of these and other pests, damageing the cell membranes. They then begin to collapse, which eventually leads to dehydration and fasting.

This soap can be phytotoxic to some plants, so make sure you test a small area before applying it on a large scale. Another disadvantage is that soap can also be toxic to beneficial insects, so use it sparingly, like any pesticide. It has been established that insecticidal soap is not toxic to humans and other mammals.


Nim is a broad-spectrum insecticide that acts as a harsh, deterrent and deterrent agent for food. In addition, it also stabilizes some insect species and slows or stops the growth cycle of others. The composition of neem includes many parts of the neem tree, originating in India. It is used in the form of foliar spraying or soaking the soil. It is used to action a variety of pests, such as aphids, thrips, diapers, white wings and thyroid glands. A unique aspect of this biological agent is its systemic properties. Plants absorb neem extracts through the foliage and roots of plants, where they are present in the tissues of plants. Therefore, nim is also effective against leaf eaters, which are usually not affected by other non-systematic foliar spraying.

In general, it should enter the body to become toxic and be practically non-toxic to mammals. Although it decomposes quickly, you should spray it only if necessary and only with plants that are known to be affected. In this way, you will minimize the damage to beneficial insects.
