If small white spots appear on succulent plants, treat them immediately, otherwise the whole plant will be wiped out even one day later!

Causes and harms of scale insects in succulent plants

Causes of scale insects: The temperature is high and the weather is hot and humid in summer. Once the ventilation is poor, scale insects are easily attracted.
Harm caused by scale insects: 1. Scale insects can cause poor growth of succulents, wilting leaves, or even falling off. 2. The honeydew secreted by scale insects can also cause sooty mold on succulents, and they will die if you are not careful!

How to treat scale insects when their numbers are small

If you find that your succulents are infested with scale insects, you must treat them immediately!

1 needle, toothpick, tweezers

If you find that there are not many scale insects on the succulents, only a few scattered here and there, you can directly use a needle, toothpick or tweezers to clean off the scale insects. However, this method is time-consuming and labor-intensive, and it is always difficult to clean up thoroughly.

2. Rinse with water

If you find it too troublesome to use tweezers or a needle to find them one by one, you can take advantage of good weather in the morning and evening, spray the succulents with water from the faucet a few times, and use the strong water flow to wash away all the scale insects.

3. Alcohol spray

In addition to the above two methods, you can also use 75% alcohol, dip a brush in it, and repeatedly wipe the leaves of succulents where scale insects appear. Because alcohol has a bactericidal and disinfecting effect, it can not only kill scale insects, but also evaporates quickly. The solution will not remain on the leaves of succulents and affect the appearance.

4 Mosquito-repellent incense

If you really don't want to do it yourself, but still want to get rid of the scale insects, you can light a mosquito coil next to the succulent flower pot, cover the succulent and the mosquito coil with a plastic bag to form an enclosed space, which can also kill the scale insects.

How to treat scale insects when there are a lot of them

Generally speaking, when you find a few scale insects starting to appear on the leaves of succulents, in fact, the hidden scale insects and eggs in places that are invisible to the naked eye have basically become rampant.

1. Spraying

If you find a lot of scale insects, spraying pesticides is the most effective method. Recently, Huahua Mall has launched a medicine that is specifically targeted at scale insects on succulents. You can mix 1g of the medicine with 2L of water and spray it on the leaves. Try to spray in the evening to prevent the medicine from burning the leaves due to strong light. If the scale insect infestation is serious, spraying once every 3-4 days is sufficient.

2 Systemic insecticides

Spraying pesticides can only temporarily relieve scale insects. If you want a long-term cure, you can also use systemic insecticides. Systemic insecticide means that no matter where the drug is applied to, it can be absorbed into the body of the succulent and then transmitted to the entire plant, killing scale insects without hindering the normal growth of the succulent. Although its effect is slow, it lasts for a long time and has a therapeutic effect on scale insects, small black flies, etc.

3Add paving stones

Adding a layer of paving stones on the potting soil of succulents can effectively isolate scale insects from entering the soil to lay eggs and reduce the occurrence of insect pests.

4. Repot and change soil

Generally speaking, when scale insects are found on a large area of succulents, there are basically a lot of insect eggs in the soil. 1. Hold the succulent with one hand and turn the flowerpot upside down with the other hand to remove the succulent from the pot.

By the way, repair the root system of the succulents, then soak them in potassium permanganate for sterilization, and then place them in a cool and ventilated place to dry. 4. Use carbendazim or potassium permanganate to clean the flower pot inside and out to ensure that the flower pot is not contaminated by scale insects. 5. Discard the potting soil that already has scale insects, or heat it in a microwave at high temperature for 3 minutes to kill all the scale insect eggs. 6. Then change the soil and re-pot it; place it in a cool and ventilated place for 1-2 weeks, and then put it in the sun for normal maintenance.
