The scabbard, as well as the false scabbard, is a harmful insect that can infect various plants. It poses a danger to a huge number of indoor plants. But especially laurel, citrus fruits, oleadra, palm, and also amaryllis can suffer from it.

Scale insects (Diaspididae) are members of the family of homoptera of the coccid suborder. Their body is rounded. And it is noteworthy that females have coatings in the form of wax shields on top of their bodies.

The false shield is a representative of a different family (Coccidae or Lecaniidae), but belongs to the same order of coccids. Their size is much larger than that of scale insects, or rather, from 3 to 7 millimeters. These insects do not have a shield, and the eggs and larvae are protected by the dried body of the female.

In both the false-scale insects and the scale insects, the difference between females and males is quite large. After the female becomes an adult, she stops moving, thus protecting the eggs attached to the surface of the plant. On the contrary, not very large males are quite mobile. At first, the larvae are also very mobile, but when they attach to the plant, they become immobile and they have a wax shield.

Types of scale insects

In nature, there are a fairly large number of species of scale insects that can harm any indoor plant. But they are very similar to each other, the difference is only in size and color.

  • scale brown - most often this insect affects: ficuses, laurel, palm trees, camellias, citrus fruits, yucca, dracaena, boxwood, oleander, hibiscus and other plants;
  • scale cactus - most of all prefers to settle on cacti;
  • scabbard olive - settles on oleander, laurel, camellias, pomegranates, citrus fruits, hibiscus, fat women;
  • scaled palm - can seriously harm palm trees. Most often, these insects damage young leaves of fan palms that have not yet blossomed. They are also dangerous for bromeliads, orchids and other tropical plants grown at home.

What is the danger of scabbards

Larvae, as well as adults, feed on plant sap. Adult females attach very tightly to the surface of the plant and stop moving, thus providing protection for larvae and eggs. In places where scale insects have settled, spots appear that have a brownish-red or yellow color. After some time, the leaves begin to turn yellow, the stems do not develop correctly, and the infected plant also sheds its buds. It practically stops growing, and its branches gradually become bare, and soon the plant itself begins to wither, and eventually dies.

Getting rid of these harmful insects is a rather laborious process. The point is that the shields they have protect them from chemicals.

Signs of infection (external)

It is quite easy to detect these harmful insects. Outwardly, they look like small convex tubercles or plaques that have a rounded shape. Their color may be different. So, they can be colored green, yellow or brown. Most often, they are attached along the veins on the leaves, both on the outside and on the inside.

It is worth knowing that the scale insects produce a sticky secret. So, if the plant is infected very recently and the females are still almost impossible to see, then the leaves become quite sticky already at this stage.

Methods of dealing with false shields and shields

After even one scale insect is found on the plant, it must be immediately removed away from others. Also, be sure to check those home flowers that were next to the isolated plant.

After the scale insects become adults, they form a shield that very well protects them from insecticides. However, they can be removed manually from an infected flower. To do this, you need to prepare a soapy water solution and a cotton swab (small soft brush). The cotton wool is moistened in the solution. Then you need to carefully wipe each leaf with it on both sides, and do not forget to process the stems.

After the plant has been mechanically treated (cleared of adult scale insects), it must be sprayed with an insecticide. Also, the surface where the plant stood and stands should be treated with a chemical. And do not forget about the surface of the window, since the larvae of this insect may be there too.

It is much easier to deal with false shields, since they are devoid of a dense shield. It is quite possible to destroy them with insecticides.

Those plants that have dense leaves of a sufficiently large size are easier to clean from the scale insects. It is enough to regularly inspect the plant and remove adult insects. Plants with small delicate leaves are almost impossible to get rid of these harmful insects. For example, scale insects can kill asparagus or maidenhair.

A simple way to deal with the scabbard

Recommended insecticides in the fight against false shields and scabbards:

  1. Bankcol - this agent of contact-intestinal action has a mild odor and destroys sucking and gnawing pests.
  2. Inta-vir is an intestinal contact agent with a wide spectrum of action.
  3. Actellik ― is distinguished by its effectiveness. It is worth considering that it has a very strong, persistent odor, therefore it is not recommended to treat plants with it in closed rooms.
  4. Aktara is a broad-spectrum agent. They can both spray the plant and bring it into the ground. So, you can simply water the plant at the root with an insecticide dissolved in water, but only if it reaches a height of no more than 30 centimeters. Through the root system, Aktara spreads throughout the plant, making it toxic to pests.
  5. Mospilan - it has a systemic effect on the plant. It is able to absorb the drug in all parts. And after that, the insecticide is evenly distributed throughout the flower, and is contained even in those parts of it that have not been treated.

Plants must be processed according to the instructions attached to the preparation. Often, a few days after the first treatment, a second one may be required, since the pests that were at the time of treatment in the scales of the bulbs, as well as in the axils of the leaves, are likely to multiply again.

In addition to these insecticides, you can spray the plant with 96% alcohol. It is necessary to use a fine spray. It is worth considering that this substance can burn the leaves, so first you need to spray a couple of leaves and see how the plant reacts. The leaves are moistened quite a bit, after which the substance should evaporate.

There are also a large number of folk recipes. So, for example, plants can be treated with garlic or onion water, pepper tincture, a solution of celandine juice, and so on. However, they can only be used in conjunction with a mechanical processing method. But if there are a lot of scale insects, then these funds will not cope with the task.


If one day, when inspecting your favorite plants, you notice an insect that looks like a flat aphid or a shell, then you know that you have a scabbard. Do not panic and immediately throw your favorite plant out of the house. You can still help him. But first you need to understand what a scabbard is and how it is harmful.

The scabbard is a very serious enemy of the florist, especially the beginner. This enemy is terrible because at the initial stage of development, it is extremely difficult to detect it, since it is mobile and small insects. We can immediately say that the best way to prevent and combat the scabbard is a thorough and regular inspection of the plants.

Let's take a closer look at the shield itself and methods of dealing with it.

There are quite a few types of scale insects, and the difference between them is in size and color. But they all have a common feature - a wax shield that covers the body, and which gave the basis for the name of this pest. It is not worth describing all types, because there are quite a few of them and this is not interesting for everyone, but it is worth mentioning that there are false shields. But, despite their name, they do no less harm.

What is the danger of the scabbard?

The body of the scabbard is only 5 mm, but this does not make it less dangerous. The whole danger lies in the fact that she sucks out all the juices from the plant after settling on it. The result is abscission, drying of the leaves, and sometimes the death of the plant, if nothing is done. Conventional scabbard control methods may not work, as the wax shield makes it immune to many chemicals. There are many known cases when the war with this enemy was completely lost. But, in fact, not everything is so scary. After all, the shield can be defeated even in the very last stages. But this requires a lot of patience, time and the right approach.

Signs of damage with a scabbard

As mentioned above, the scale insect is very difficult to detect at an early stage, because it is a rather small insect that moves very quickly. Although it is the active movement that betrays her. And even if you do not have sharp eyesight, you can use a magnifying glass. The next time you inspect the plant, you will not be able to miss the movement along the stem and leaves of the plant. After that, you must immediately strike a preemptive blow. But adult scale insects can be easily seen with the naked eye, even if you have poor eyesight. They often appear at the place where the cutting of a leaf adjoins a branch or trunk, and their most favorite place is the bottom of the leaf. Scabbards look like specks on leaves, trunks, etc.

Still, there are cases when the florist did not see them. But here, too, there is no need to despair, because the next sign of a scabbard attack is very pronounced. A sticky liquid (the so-called pad) begins to appear on the leaves, and sometimes it becomes so much that this pad begins to flow down the leaves onto the windowsill. This becomes especially noticeable when the scale insect attacks the lemon. Because of this sticky liquid, the situation is aggravated even more by the fact that a sooty fungus develops on it. The list of plants (indoor) that the scale insect can easily attack is very long. These are many of ivy, citrus, palms, oleander, croton, ficus, yucca, dracaena, pachistachis, fat woman. But this is only the beginning of the list ...

Methods of dealing with the scabbard

If you managed to spot this parasite at an early stage, when it is not protected, then it is enough just to carefully and diligently spray the plant with an insecticide solution. However, if this moment is still missed, then the fight will become a little more difficult. Do not think that to get rid of the scabbard, it will be enough for you to raise the humidity, as is necessary for a spider mite, or to spray it with a solution of laundry soap, as required by aphids.

Mechanical cleaning is what will help remove the shield. Yes, with your own hands. Naturally, using improvised tools such as an unnecessary toothbrush can help. Many recommend using cotton swabs, which must first be moistened in a solution of Actara or Karbofos.

The mechanical method is quite reliable, but only if you have a lot of patience and can remove all the pests. The whole problem is that the scale insect reproduces at a tremendous speed, and there are viviparous, and there are those that lay eggs. They become immobile, as they guard their offspring. And if you missed at least one speck, then all the work was in vain. But florists recommend radical methods.

Immediately after you have removed all the parasites from the plant, you need to carefully spray it with a solution of actara. Pay special attention to the inside of the paper (this is their favorite place). A young or not tall plant must be watered the next day with the same solution. After, a week later, repeat the procedure. In this case, first of all, the plant affected by the shield must be isolated from others, and the place on which it stood, and, preferably, the neighboring plants, must be carefully treated with aktar.

Since almost all insecticides have a pungent odor, and are also toxic, it is better to carry out the treatment in a non-residential area. Another important detail should be taken into account: watch the humidity of the air, since if it is increased, then this is an excellent condition for the reproduction of the scale insect. Therefore, in sunny summer weather, it is better to take the plant out into fresh air and place it where there is good lighting. Bright light slows down the development of scale insects.

Scabbard discovered - how to fight on your own?

If you do not know how to deal with the scabbard, read some tips from experienced gardeners. Infected branches (shoots) should be cut off and destroyed by burning or insecticide treatment in order to prevent the spread of the infestation.

Beneficial predatory insects such as parasitic wasps or ladybugs may be used.

Release predators directly into the garden or garden. After they have eaten all the scale insects, they will leave on their own.

Folk methods of dealing with the scabbard

1. Treatment of plants with a solution of vinegar, garlic or onions.
2. Using potash green soap.

Just as with the application of chemical methods, the treatment must be repeated regularly and the plants must be carefully examined for the appearance of new individuals. It often happens that the scale insect affects not a single plant, but all nearby indoor flowers. Scabbard on indoor plants - how to fightwhat to use and what to process - all this will help you keep your flowers safe and sound. Methods to combat this parasite are quite simple and affordable, the main thing is to start the fight on time, preventing the death of the plant.

Scabbard on indoor plants

Reasons for the appearance

Parasitic insects enter an apartment and a private house in several ways:

  • with new plants from the flower shop. Insect larvae can be found in the ground or on leaves, and in the absence of a two-week quarantine, pests easily migrate to neighboring specimens from a green corner
  • through open windows from shrubs and trees located next to the house
  • from the soil brought by the hostess from the flower bed for planting a new plant. Various pests often settle in the ground near residential buildings, their larvae and eggs are found.

How to get rid of scale insects on plants

Measures to combat the scabbard should be comprehensive.

The first thing to do if you find an insect on a plant is to isolate it from the rest and cut off the infected leaves.

The area where the flowerpot was located should be treated with a solution of soap and then alcohol.

The most effective chemical agents in the fight against parasites are insecticides.

This is especially justified if more than one plant in the house is affected.

However, chemicals will practically not work on adults, they are protected by a shell, you will only destroy young insects and scale insects.

In this case, you will have to remove insects mechanically. Use a sponge or cotton pad. Soak them in soapy water - tar or household will do. The resulting foam solution must be applied to the plant very carefully. You need to wait about half an hour, then wash off the soap with hot water. The procedure should be repeated daily for a week and after another week, repeat once.

Alcohol, gasoline and kerosene cannot be used to treat plants, so you can harm it even more.


For an alternative fight against the scale insect using chemicals the following drugs are effective:

After applying chemicals to the infected plant, immediately ventilate the apartment well. It is safer to do chemical processing outdoors.

Folk methods of dealing with the scabbard

For adherents of folk remedies, the well-known means of combating parasites are suitable - onions and garlic and peppers.

Soap almost always appears in the composition of solutions from the scabbard.

To prepare the onion solution, you need to take a medium-sized onion, chop and pour a glass of water. Let it stand for a couple of hours. Spray the diseased plant with the prepared solution.

Solution from pests "Pertsovka" done like this: mix 50 grams of fresh pepper with 2 glasses of water and boil, then let it brew for a day. Mix the filtered liquid with soap and process the plant.

It is not recommended to repeat the procedure often.

Garlic solution done in a similar way. Chopped garlic must be kept in a closed container for a day, after which it should be sprayed with a flower from a spray bottle for a week. The second option for preparing the solution involves boiling the garlic and letting it brew for several hours.

The folk recipe for oil-based scale insects is as follows. You need to mix a glass of water with 10 grams of soap and 20 milliliters of sunflower oil. Covering the very ground of the plant with plastic wrap, process the stems and leaves and wash off after 6 hours. A second procedure will be required in a week.
