Aphids on succulents
The aphid is one of the pests that most commonly affects all types of plants. These insects are commonly green in color, although there are also black and yellow, all of which are a few millimeters in size. They feed by sipping the juices from the leaves and stems of the plants, but they also secrete a sugary substance that promotes the appearance of ants and a black fungus.
The best for remove aphids from succulents is to use a home remedy in the form of insecticide for succulents, always making an ecological one ourselves or buying an ecological one, always without resorting to those that are commercial chemicals too harmful to plants.
- One of the most practical with succulents is use 70% alcohol diluted in water. By spraying a spray on your affected succulents, 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 use it even preventively. Of course, always apply it at dusk so that the sun does not shine on them and thus avoid sunburn on the leaves. You can also bring them into the house and avoid direct sunlight during the treatment days.
- Against aphids it 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 when mixing it, it will dissolve more easily. As with alcohol, spray the plants at dusk, looking for the areas most affected by the pest, and so you should not take long to notice the effect. Here we tell you how to make potassium soap.

How to eliminate the cottony mealybug on succulents
The cottony mealybug it is another of the most feared and common pests. They are insects of about 4 mm in size, light in color and covered by a white layer of a substance that they 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 by that species of "cotton" that gives them their name and which is actually egg sacs.
It is a dangerous pest 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 swab or cotton impregnated with alcohol or potassium soap. If not, it will be better to spray with a solution, as with aphids.
We can also use Dishwasher 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 surfaces, it is applied by mixing a tablespoon of the oil in two liters of water and spraying the solution on the plants, at dusk and once a week.
