Are you looking for a natural pesticide for your plants? Here is the baking soda trick and other very effective recipes to try immediately.

Anyone who has a flowery garden or balcony knows how difficult it is to eradicate parasites: these small insects attack plants and consume their lifeblood, often seriously damaging them, if not even causing their death. There are many types of parasites, some very common – it is practically impossible not to have ever had to deal with them – and others that are decidedly rarer. In any case, it is necessary to resort to some remedy to protect plants from their devastating effects. How to do? There are many chemical pesticides on the market, but it is possible to try natural solutions first . Let’s discover the best.

Goodbye parasites: how to eradicate them

From ants to rose lice , your garden is constantly in danger. And if you only have a small balcony with a few seedlings here and there, you are not safe anyway: parasites really arrive everywhere , and cause serious damage to flowers and crops. It is important to act quickly when you notice the first signs, thus trying to prevent a real infestation. However, if it is too late, don’t waste any more time: you will have to find the best pesticide for your needs.

But are chemical insecticides the right choice? We are talking about products that are effective against parasites, but are also highly polluting and often dangerous for health. Thinking of using them on fruit and vegetables, but also on your aromatic herbs that then end up in the kitchen, is not exactly the best. Better to try natural remedies , more environmentally friendly and often much cheaper, because they are prepared with ingredients available in every supermarket. Here are some very effective ones.

Natural pesticide with baking soda

There are ingredients that we all have at home, and which incredibly have a repellent action against insects and parasites . One of these is  sodium bicarbonate : a perfect ally for household cleaning and flawless laundry, it is also useful for preparing a cheap and super effective DIY pesticide. Not to mention that it is harmless to plants and above all safe for humans. Let’s see the best ways to use it to protect your crops.

First, sprinkle a little bicarbonate of soda all around your plants, both on the garden soil and on the floor of the balcony, where you have placed the flower pots. In this way, you can keep earthworms, snails and ants away: for them, this common, usually harmless white powder is a real danger. For greater effectiveness against parasitic infestations, dissolve 3 tablespoons of bicarbonate in 4 liters of hot water and pour everything into a spray bottle, nebulizing the mixture on the leaves and surrounding soil.

If you want an even more powerful remedy, excellent not only for fighting parasites but also against fungal infections of plants, then fill a spray bottle with 1 liter of water, adding 4 tablespoons of bicarbonate and 60 ml of olive oil . Once everything is mixed well, spray the solution on the leaves and around the plant, avoiding the fruits and flowers. Even better if you do it early in the morning or in the evening after sunset, to prevent the water from evaporating immediately in the sun.

All natural parasite remedies

Of course, the baking soda trick isn’t the only one you can use to get rid of parasites. In the case of scale insects or aphids, for example, a very effective remedy is Marseille soap . This product, even before being the best solution for household cleaning and laundry, is widely used in agriculture to protect plants from some parasites, especially in the cultivation of aromatic herbs, vegetables and small fruit trees .

To prepare the pesticide, cut a block of  Marseille soap into flakes and dissolve it in a saucepan full of water, heating it over low heat until you have obtained a homogeneous mixture. Let everything cool down and transfer it into a spray container, using it on the leaves and flowers you want to defend against parasites. If you want to make it even more powerful, add a few drops of Neem oil , which contains an active ingredient that is excellent for keeping insects such as beetles and red spiders away.

Another natural solution is propolis : this substance produced by bees contains flavonoids in large quantities, which stimulate the plant’s metabolism and strengthen its defenses. Preparing this pesticide is a little more complicated, but it’s really worth it because it is very effective and safe, both for humans and for the vegetation itself. Start by preparing an aqueous solution : pour 150 g of propolis into 1 liter of water, adding 1 g of soy lecithin. Leave to macerate for at least two weeks. At the end, pour the mixture, filtering it carefully. The residues will be used for the alcoholic solution.

The latter is prepared by pouring the residue into 1 liter of 95° ethyl alcohol , also in this case adding 1 g of soy lecithin. Leave to macerate for a couple more weeks, mixing well at least once a day. At the end, filter the mixture obtained. The last step consists of mixing 100 g of aqueous solution with 100 g of alcoholic solution. Take 10 g of the mix thus formed and dilute it in 5 liters of water : here is your pesticide to spray on the plants in the garden or balcony, to fight parasites and fungi.

Then there are other macerates that are easier to prepare, but just as effective. The first is nettle macerate , which has a really unpleasant smell for insects (and is actually quite unpleasant for humans too). Collect 1 kg of nettles without roots and put them to macerate in 10 liters of water for at least a couple of days. Filter the solution obtained and pour it into a spray bottle: the insecticide is ready, you just have to spray it on the plants without needing to dilute it further. The additional idea? Let the nettles soak for a couple of weeks, and you’ll also have an excellent fertilizer .

Finally, let’s see how to prepare garlic macerate : this bulb, which gives off a certainly not pleasant smell, contains significant quantities of  allicin , an antibiotic substance with strong antiparasitic properties. Crush 75 g of garlic and put it all in a container containing 10 liters of hot water. You will have to let the mixture macerate for at least 5 hours, before filtering it and transferring it into a spray bottle . Spray the garlic macerate on the plants without diluting it, preferably early in the morning or in the evening.
