Кроме того, зимой насекомые появляются и дома. Казалось бы, должны исчезать хоть на время, но нет. Оказывается, мраморный клоп часто живет рядом с человеком – в щелях домов, под обшивкой, где тепло. Я сама видела, как они выползают откуда-то из недр жилья. Мало того, приходится травить насекомых летом на полях, теперь еще и зимой – дома. Обращаюсь к вам, т. к. ищу способы борьбы с ними. На огороде и в саду использую химические препараты, но что делать дома, какие методы можно применить, посоветуйте. Заранее благодарна, Гела.
The author of the portal answers the question:
In my material below, you will learn how to control the marble bed bug.
This is Insect is characterized by its unusual coloring, which gave rise to its name. The marble bedbug looks as if it is actually made of stone. Because of this, the pest is not always noticeable. In various countries, it is considered one of the most dangerous, because it rapidly destroys plantings. People have come up with many methods of dealing with these by insects.
Engage special meansThe use of the following methods, as well as improvised devices, scent baits, traps, repellents, etc., can help to reduce the risk of infection.
What the marble bug (Halyomorpha halys) looks like
The pest is a prominent representative of the Shieldworts. It belongs to the family Pentatomidae. The insect has a brownish-gray coloration. Moreover, the pattern is specific, which contributed to the appearance of the name - marbled (halyomorpha halys). Other external features:
- body length is longer than that of their counterparts of other species - up to 17 mm;
- light rings on the antennae;
- 3 pairs of limbs;
- on the underside of the body is light, rarely observed black gray dots;
- The limbs are also decorated with rings;
- have wings, adults are able to fly.
In which areas of Russia the brown marble bedbug prefers to live
It is believed that insects Came from the East - from Southeast Asia. But at the end of the last century, a gradual spread of such pests was noticed. They appeared in the United States, then - in the territory of Europe. This was facilitated by accidental migration together with the belongings of travelers.
The brown and marble bedbug is common in Russia today.
Lifestyle of the beetle
The insects made themselves known when they began to actively settle next to human habitation, literally in homes, but not inside the premises, but in cracks, under upholstery, exterior upholstery materials.
Here they found ideal conditions for wintering.
If, on the other hand temperature outside will slightly increase in winter, accordingly, it will also become warmer in the shelters, the pests immediately get out. As a result, a large number of insects are found inside houses. However, this problem occurs in private housing.
The pests feed on plant food. Their diet consists of more than 100 plant species. And the insects quickly destroyAs they gather in large numbers, they bring new offspring en masse.
This pest likes fruit, berry plants, grain crops and, of course, vegetable crops the most.

Peculiarities of the development of the marble bug: the stages of insect formation
A female can lay up to 30 eggs in one approach. These rounded formations are up to 1.6 mm in size. The duration of insect development is 30-45 days. Larvae form in stages; they go through five phases of maturation, molting at each. The pests have no ability to fly until they reach sexual maturity.
The coloration of juveniles constantly changes as they shed their outer covers. At first they are characterized by a red or orange color. Then the cuticle of the insects darkens to black. In the last stages, they lighten, acquiring their usual coloration.
A total of 3 pest generations appear during the warm season; only adults go to wintering.

Types
There are many varieties of bed bugs, and they are represented by many families. They are divided into groups according to similar external features, eating habits, and peculiarities of life activity.
The brown and marble bedbug, on the other hand, is isolated in the midst of all this diversity.
It is alone in its genus, and therefore it has no similar counterparts in appearance. However, in the range of its habitat are noted insects, which are often found, also belong to the species bedbugs.
Nezara Green
It is a green vegetable pest. The insect is dangerous because of its fecundity (it can lay up to 350 eggs). Most of the time the outer covers are green, but in autumn the cuticle changes color to bronze. Sometimes individuals with brown pronotum and head are found.
Berry Shield
The insect has a bright coloration - the body is reddish-brown, sometimes lighter in color, with visible puncturation on the sides. The insect is also distinguished by its glossy shine. Its body length is up to 12 mm. It feeds mainly on fruit and berry plants, sucking sap, but it can also destroy plantations of other crops.
Harm to agriculture from the marble bedbug
The pest promotes the emergence of several generations per year. All juveniles are no less voracious than adults.
The danger of pests is that they have no natural enemies in most parts of Russia.
The insects have already gained fame for destroying crops and, at the same time, the yield of fruit trees. Several years ago, they appeared en masse in Abkhazia and Sochi. Here the pests contributed almost twice as much to the decrease in the yield of fruit trees.
What plants are dangerous to the marble bug
It destroys a large number of plantings, crops. Among the most beloved:
- tomatoes;
- eggplants;
- nuts;
- figs;
- olive;
- pepper.
It would be difficult to list a few dozen plants. It is enough to know that fruit trees, berry trees, vegetable crops, grain crops, and even ornamental flowers are at risk on the plot.
Signs to determine if a plant-eating bug is present
The changes that happen to plants:
- necrotic areas on the bark of trees, here the trunk softens;
- Premature fall of the fruit;
- fruits, vegetables are susceptible to rot, changing their taste;
- spots also cover the fruits of trees and shrubs;
- fruits become lumpy;
- the leaves of the plant dry out;
- in areas where punctures are made, the color of the tissues of the green part of the plantation changes.
When a brown-marbled bedbug appears, the risk of phytoplasmosis increases.
This disease is accompanied by the appearance of spots on the leaves, gradually the green part of the plant turns completely yellow.

Are Marble Bugs Dangerous to Humans
The insect, like all shieldflies, is not adapted to attack humans. The brown and marble bedbug contributes to the allergies in those who suffer from hypersensitivity. The reaction in humans is caused by the secretion secreted by the glands of the insect.
Sometimes a strong odor can also cause discomfort in the eyes, throat, because it releases volatile substances into the air.
Contact with it rarely causes dermatitis (redness, itching). Shields - are not parasites, they do not drink the blood of warm-blooded creatures, but are herbivores.
Is the strength of the mouth of the Asiatic Shieldwolf strong enough to bite a person?
It is one of the varieties of pests of the Shieldworm family. It is also called the marble bug. Such a pest does not have the physical ability to pierce human or animal skin, despite information from some sources.
How to fight the marble bedbug - the best ways, methods of action on the bedbug
These insects are affected by different means, and you can get a good result of treatment, even if you use deliberately weak substances, preparations.
The best way to protect against brown marble bed bugs is the combined method, when using different types of products (chemical and biological basis).
Poison recommended by the Ministry of Agriculture of the Russian Federation
Insects gradually develop resistance to the used to insecticides. According to the recommendations of the Ministry of Agriculture of the Russian Federation, the most commonly used funds:
- Actara. The main active ingredient is thiamethoxam. The drug is one-component. It is characterized by its ability to affect individuals through the intestine and chitinous membrane.
- Klonrin. Concentrated two-component product, contains neonicotinoid and pyrethroid, which allows you to increase the effectiveness of treatment, reduce the risk of developing resistance and accelerate the destruction of bed bugs by getting them a double dose of poisons of different types.
- Tanrek. Form release form - liquid concentrate. It contains imidacloprid (neonicotinoid).
- Karate Zeon. It is a microencapsulated preparation that provides long-term plant protection. The preparation was developed in Switzerland and contains pyrethroid - the substance lambda-cyhalothin.
- Clipper. It contains bifenthrin, which is a pyrethroid. Its advantage is the ability to kill insects at different stages of development (eggs are killed too).
- Confidor Extra. It contains neonicotinoid, the drug belongs to the group of intestinal contact.
- Calypso. The composition includes chloronicotinil, while providing a double effect: the substance acts through the digestive tract and the cuticle.
All the remedies of these types affect the nervous system.
As a result, death occurs in a matter of hours, a maximum of one day.

Subtle effects of pheromone bait on plant-eating pests
Halyomorpha halys stal bugs, unlike other species, can be killed with substances of a special odor. This is how a pheromone trap works. It is used in the garden and vegetable garden.
The principle of action is based on attracting insects with a special substance.
The pheromone dispenser performs this function. It holds the secret of the species Plautia stali. The trap is fixed in different places, for this purpose a strong wire is included.
Biological way
There are no natural enemies for these pests in Russia. The Samurai wasp helps control their numbers in East Asia. Its habitat requires special conditions that are difficult to create in the Russian Federation, for example, in order to eradicate the marble bug in Abkhazia.
Preparations based on spores of fungal strains
Such remedies belong to the natural ones. They are called biopreparations. They are based on harmful microorganisms. In this case, we consider agents based on fungal spores.
In practice, it turned out that Beauveria bassiana destroys young second instars (larvae).
And the efficiency is quite high - if treated in time, more than half of the pests at the initial stage of development are killed.
Mechanical beetle collection
This method of control is recommended when the area is small. Catching bed bugs is carried out provided that a container of liquid has been prepared so that the insects cannot escape. But this method can be used as an auxiliary, as it does not provide 100% results.
Traps with their own hands
When choosing a way to get rid of the marble bug without harming the plants, consider improvised means. Their advantages: low cost, ease of making a trap.
Falszimnick
Gardeners know that marble bed bugs when it gets colder seek shelter where it is warm. Especially for them constructions are created: boxes (from improvised materials: cardboard, plywood) are filled with paper (shredded). Here the insects will find shelter. The boxes are suspended at the level of 2-3 m.
Marble Bed Bug Trap burnedwhen there are many individuals inside.
Light Trap
Insects are collected in wide trays with low sides. They are filled with soapy solution, placed under light sources, which will attract pests, and they will not be able to get out of the sticky liquid.
Where to buy ready-made traps and at what price
Before buying, you need to orient yourself in the price ranges of such products. Different offers are studied. Some of them are presented in the table.
What to do if you got into an apartment
It is necessary to find the source of pests entering the object. If this is not done, you will have to observe such individuals in your home more than once in the future.
Block the bed bugs from entering the room
Examine the object from the outside. Insects look for the smallest gaps in the panelling, plinth, windows, doors. If you manage to find traces of life in one of the areas, you first need to lure pests, and then you can remove the leaks, taking into account the properties of the materials.
Repel bugs with garlic
Strongly scented substances are used against bed bugs because these insects use their senses to navigate in space. Garlic is also used as these insects do not like it.
Spread the cogs everywhere where pests can appear.
You can also crush garlic, pour water on it, after a while the liquid treats the paths of likely penetration of marble shields.
Vacuum cleaner
If pests are already in the cracks, you need to get them out. You can try the action of traps. Alternatively, a vacuum cleaner, but then the technique will be ruined - there will be a strong smell of insects inside, as they will sense the danger and will emit a smelly secret.
Kill bed bugs with soapy water
Surfaces where there are insects are treated with such a product. It is easy to prepare: any amount of soap is dissolved in water. Then use a sprayer to sprinkle the areas.
Soap corrodes the cuticle of the marble bug.
The method of control will result in the insects soon not being able to move.
Hairspray is an effective way to immobilize insects
It is enough to treat the surfaces with a hair styling product.
The sticky substance will not allow the pests to fly away.
This will make it possible to freely collect the insects and then burn them. But when they are already crammed into the cracks, this method is not used, because the varnish will not allow the pests to fly away, which will contribute to attracting predators - other insects.
Cuticle burns from red pepper pests
This should not be taken literally - marble bedbug is not eaten. What is meant is the preparation of a concentrated solution based on red pepper powder. It is necessary to make a spicy remedy, and then it is sprayed over the surfaces.
Red pepper will literally burn off the outer covers of the pests.
Vinegar baths
If marble bed bugs have appeared, how to get rid of them - use strong-smelling improvised tool. It is necessary to prepare a solution (vinegar and water in a ratio of 1:1). Spray it with a sprayer over all surfaces and areas where insects have been encountered.
Exterminate bed bugs with diatomaceous earth
This powder is sold in a polymer bottle. It is enough to scatter it everywhere and the pests will die in a few hours/days.
Diatomite is a natural remedy, when in contact with the cuticle of imago, its integrity is violated, which leads to increased drainage of fluid.
As a result, the insects die of dehydration.

Vegetable gardeners' reviews
Expert tips
- When hibernation ends, bed bugs will fly over, so if you don't want these insects to get into your garden, cover the plants they are most attracted to with fine mesh mesh or minimal density agrofiber;
- I do not recommend the frequent use of insecticide-based products, even the most effective ones lose their properties, do not work on bed bugs with resistance.
Conclusion
Marbled pests have a number of similarities with their counterparts in the Shieldworm family. They have a flattened body, brown coloration, with light spots on top of the torso forming an interesting pattern, it resembles a marble crumb. Other features:
- Bed bugs hide closer to people's homes. This is where they get access to heat sources, which is important when the weather gets cold.
- The main harm caused by such species is the destruction of plants. Bed bugs affect different types of plantings - many dozens of them.
- Insects suck the sap. This causes the leaves, stems, and flowers to wilt.
- Humans are not attacked by such pests. However, they have their main weapon - a strong unpleasant smell.
