Garlic insecticide spray

Garlic is a powerful natural insect repellent, capable of deterring and driving away many insects from our garden. To prepare our insecticide, crush a head of garlic with some cloves (spice) in the blender, along with two glasses of water to obtain a well homogeneous compound. Let it rest for a day and then mix in 3 liters of water. The mixture obtained can be vaporized directly on the leaves of the plants. Garlic infusion is also quite effective in fighting aphids.

Fungicide with milk

There are many ways to combat fungi, some better than others, but with this home remedy (as well as cheap) and ecological we will have a great weapon to combat and prevent them.

Chromatic traps to combat whiteflies

To combat the whitefly we are going to use a very simple principle and that is that many insects are attracted to the color yellow, this is the basis of the chromatic traps that knowing that they are attracted in an irresistible way towards that color, we can always catch them one Once they are perched on it, with adherent materials such as glue, honey, etc ...

Ecological remedies for snails and slugs

For everyone who has plants outdoors and especially for people who have a garden, snails and slugs are usually one of the biggest problems they must face, both because they eat the leaves (which is the least serious) but especially because even sprouts of newly planted plants, you can leave us a simple stem in such a way that that plant will no longer have a future.

As always in a matter of home remedies, the ideal is to apply it when snails or slugs become a plague, if we have few snails and the damage is not very serious, my recommendation is to do nothing.

Nettle tea

How many times have you accidentally touched a nettle leaf and had that annoyingly itchy sensation? Well, nettle may not be so annoying when it becomes a great ally for your crops. Put on a pair of thick gloves and pick up some nettle. Put it in a bucket and cover it with water, let it sit for at least a week and you will have your new 100% organic liquid fertilizer.

Tomato insecticide

Tomato leaves are rich in alkaloids, an excellent repellent for aphids, worms and caterpillars. Fill two cups with chopped tomato leaves and add water. Let it sit for at least one night and dilute the mixture in two glasses of water. Ready! You can spray tomato spray on the plants. Keep it away from pets because it can be toxic to them.


Eggshells are an interesting ingredient for our garden. They have a double benefit, they can be used as a fertilizer or as a repellent, in chunks or ground. Crushed, sprinkle the powder at the base of your plants, or in pieces, creating a kind of ring at the base of the plant: this barrier can keep them from snails and some caterpillars.

Macerate tobacco

The nicotine present in tobacco leaves can be a great repellent for insects. To prepare the tobacco macerate put 3 or 4 cigarettes in half a liter of water. Let it marinate for two days and then filter or pass the liquid through a fine strainer. Put in a vaporizer and your natural insecticide is ready.

Ginger tea to combat the tuta or tomato moth

This moth wreaks havoc on our nightshades, especially tomatoes, with ginger tea we are going to combat this pest that pierces our fruits. In addition, ginger is very easy to grow at home.

Pepper Insecticide

Pepper is a natural repellent against pests. To prepare the spray, beat 6 to 10 chilies (any type) with two cups of water in a blender on high speed for 2 minutes. Leave the mixture overnight. The next day, filter and add a glass of water. Pour the liquid into the sprayer.

Nematode friends

I know it may seem strange but there are friendly worms for your garden. Often, to control the population of some pests other pests are necessary, or on the contrary, other antagonists of insects. This type of good nematode is capable of killing many of the pests in your garden or orchard, including beetles, weevils and others. It can be bought in specialized stores.

Eliminate weeds with newspapers

Here is a trick to eliminate weeds in your urban garden or plot of land without using herbicides or toxic chemicals, so we will not damage our land. With some newspapers, a little work, no maintenance we will achieve a higher quality land without weeds.

As we've seen, you can do a lot to preserve your crops without the use of chemicals and pollutants. Once again it is nature that gives us the solutions to problems.
