Natural and Homemade Insecticides

Natural insecticides or homemade insecticides are the need of an hour. We don’t want to let insects destroy our crops and plants but also at the same time, we don’t want to destroy our environment. We all want that satisfy our present needs, without destroying the environment for our future generations. Let’s see some of the ways to do it. People might think that homemade insecticides are less effective than chemical insecticides. But that is not at all true. Homemade insecticides are as effective as any other insecticide and in fact more effective than artificial ones. It might take a little more time as compared to artificial insecticides but still, it is worth it.

Let’s see what are the differences between the different chemicals that we use in our gardens:

Pesticides: Chemicals or substances used to destroy insects, plant diseases, bacteria, fungus, slugs, and snails.

Insecticides: They come under pesticides only but as the name suggests, they are used exclusively to kill insects.

Herbicides: They are the chemicals used to destroy weeds. Specific herbicides can be made for specific kinds of species. And if proper knowledge is not there, the whole plant crop could be destroyed.

Also, I would want to say that if you don’t want to make insecticides at home, you can get organic one from the market as they are also made of natural products and are also helping us to save the environment. But organic products are quite expensive. So, to avoid the expense you can either handpick the insects from your plants and garden which is an effective method but also very time-consuming. Or you can just make homemade insecticides which will solve a lot of time and will be an effective method to save your crop.

To make this, use one cup of white mineral or vegetable oil and one tablespoon of soap. Pour the ingredients into a container and shake it well. But before applying it to the plants, make sure to dilute it. Use this homemade insecticide once a week on just the affected plants. This works by wrapping the insect’s body with oil and suffocating them by blocking their breathing holes.
