How to get rid of caterpillars

The caterpillars are the larvae of insects of the order Lepidoptera, which includes butterflies and moths. There are many chemical products used to protect plantations. These can be potentially toxic to human beings and produce harmful effects on our health. In this article, we explain how to get rid of caterpillars in trees.

In the first phase of its life cycle, the butterfly or moth lays the eggs in the plant. In a few days, the caterpillar is born, characterized by a healthy appetite and the need to feed continuously to develop and become a new butterfly. It is this voracious and aggressive appetite that gives rise to one of the most frequent problems that we find in plants and crops. It can cause, in the event of plague, damages so severe that they determine the total loss of the crop.

How to get rid of caterpillars in trees?

Detecting the presence of caterpillars in the garden or mint plants is relatively simple, firstly because of their size and colors. Secondly, because of the visibility and evidence of the symptoms, they produce in vegetables.

Some of the symptoms of caterpillars in plants that can be noticed more easily are galleries, defoliation, holes, and bites in the superficial leaves. They can also attack and feed on tender shoots and fruits. Also, you will see an accumulation of black spots on the leaves, which are the feces of the caterpillars.

How to remove caterpillars naturally with organic pesticides

Making a pesticide or pesticide home without chemicals to ensure the health of the plants and not generate toxic waste is relatively simple. Knowing the properties of some plants and other natural products. These are ecological pesticides that we recommend to eliminate the caterpillars of plants naturally :


It is a natural insect repellent. Crush a garlic head together with a couple of water glasses and let it stand to get an effective insecticide. Although, it is true that, to facilitate its application it is advisable to mix it once again, once it has been left to stand, with three liters of water, to achieve a more liquid and easy to spray product.


The tomato plant produces during its metabolism molecules called alkaloids that act as an excellent repellent to scare aphids, worms, and caterpillars. For the preparation of the pesticide consists of crushing or chopping the leaves of this plant and mixing them with water, letting the mixture rest. As in the case of garlic, it is advisable to dilute the mixture again so that its use is more comfortable.


Also known as Chinese parsley, cilantro is a plant native to Asia, which has multiple properties, used for digestive problems, infections caused by fungi and bacteria, some pains and of course, to repel the most annoying species of our gardens and orchards. For its application, it is necessary to boil the plant for about 10 minutes, strain the mixture and spread it with a spray.


It is a plant considered “weed” for proliferating in the fields and gardens and for causing stinging and inflammation in the skin. There is contact with it due to the release of an acid substance located in its hairs. It is also known for its medicinal properties and for being an excellent pesticide. Mix 100 grams of nettle with 10 liters of water and letting it rest. After a while, we obtain a perfect pesticide.


The tobacco plant has an alkaloid called nicotine that acts as a repellent against pests. By mixing about 60 grams of natural tobacco with 1 liter of water, we can obtain an excellent pesticide.

Egg shells:

There are other natural products of animal origin, such as eggshells. In addition to being a perfect repellent has multiple benefits for plants, acting as a fertilizer rich in calcium carbonate. Its application comprises crushing the shells and spreading them at the base of the plants.

Prevent and eliminate caterpillars in plants with natural balance

Another effective, natural and respectful method with the environment and with our plantations consists. Precisely, in propitiating the biodiversity of the species and their balance. So that, by planting allied crops or favoring the existence of certain natural predators. It is possible to fight the appearance of pests such as caterpillars.

This is the case of plants such as basil, calendula, mint, and sage, which have such strong odors that caterpillars and other insects rarely tolerate. Thus, acting as a perfect repellent. Put some of these plants around crops where you have ever detected the caterpillars.

It is to use certain natural predators since some feed on caterpillars such as parasitoid wasps, predatory wasps, beetles, frogs, toads, and birds. In this way, favoring its presence in the habitat, through techniques such as the installation of nesting boxes for some birds, or the maintenance of humidity and ponds for frogs and toads, we can guarantee the health and safety of our plants in the long term.
