aphids on succulents
The aphid is one of the pests that most commonly affects all types of plants. These insects are commonly green, although there are also black and yellow, all of them a few millimeters in size. They feed by sipping the juices from the leaves and stems of plants, but they also secrete a sugary substance that promotes the appearance of ants and a black fungus.
The best for remove aphid from succulent plants is to use a home remedy in the form of insecticide for succulentsalways making an organic one ourselves or buying an organic one, always without resorting to commercial chemicals that are too harmful for plants.
- One of the most practical with succulents is use 70% alcohol diluted in water. By spraying your affected succulents with a sprayer, you will kill the aphid quickly. Normally plants do not tolerate alcohol well and it can harm them, but succulents are so strong and resistant that they are not affected by it. So much so, that you can even use it preventively. Of course, always apply it at dusk so that the sun does not hit them and thus avoid sunburn on the leaves. You can also bring them indoors and avoid direct sunlight during the days of treatment.
- Against aphids also works very well potassium soap, another great ecological insecticide used against a large number of pests. It is very easy to acquire and you simply have to dissolve a tablespoon of it in a liter of water. If you heat the water a little while mixing it, it will dissolve more easily. As with alcohol, spray the plants at dusk, looking for the areas most affected by the plague, and it shouldn’t take long to notice the effect. Here we tell you how to make potassium soap.

How to Get Rid of Cottony Mealybugs on Succulents
The cottony mealybug It is another of the most feared and common pests. They are insects about 4 mm in size, light in color and covered by a white layer of a substance that they themselves produce and that accumulates in plants. They usually accumulate on the underside of the leaves or under the roots, although they are easier to distinguish because of that kind of “cotton” that gives them their name and which is actually egg sacs.
It is a dangerous plague because the substance they produce can cause the appearance of other diseases, such as black fungus, so it must be remedied as soon as possible. If we locate the pest in a very early stage, we can remove the insects ourselves manually, with a cotton swab or cotton impregnated with alcohol or potassium soap. Otherwise, it will be better to spray with a solution, as with the aphid.
We can also use dishwashing soap diluted in water or neem oil, very effective remedies against many pests in succulents. Neem oil is an ecological product that can be purchased online or in specialized stores, it is applied by mixing a tablespoon of the oil in two liters of water and spraying the solution on the plants, at nightfall and once a week.
