What is a bear, its beneficial and harmful properties, methods of struggle

Hello! How happy I was when I was able to build a greenhouse on my site.

I was already looking forward to gathering huge harvests of vegetables. But reality turned out to be very cruel. And my first problem was the activity of the bear.

At first, I was even shaking from anger and powerlessness. I had no idea what could be done about this pest. But now I was able to rectify the situation. Want to tell you what a bear is and why it is a serious threat to any site? Then read in the article below a detailed analysis of this issue.

Bear, cabbage or earth cancer - a dangerous insect - a pest

What is a bear, every gardener knows, including even inexperienced "green" beginners. Everyone who at least once in his life held a shovel in his hands, of course, came across round through holes in well-groomed beds, digging out which you can find the egg laying of a pest or an adult.

From under the shortened elytra, the developed wings, which are folded, are clearly visible. In front of the body there is a pair of limbs with sharp teeth, which are an excellent digging tool that allows the bear to make moves - tunnels underground.

The body color of the insect is brown, the belly is a shade of light ocher, the head and chest are dark brown.

Despite the fact that the bear lives mainly underground, it can fly perfectly, run on the surface and even swim quite well. An insect is selected from its underground minks very rarely, mainly at night.

Earth cancer is omnivorous. Basically, it feeds on the roots of cultivated plants, paving the way for them underground, but does not disdain various types of insects, eating earthworms, earthworms and other larvae.

Medvedka prefers well-moistened and fertile soil. In early spring, it attacks seeds (including only sown ones), gnaws stems and roots of cultivated plants, and can even harm the roots of young fruit trees, shrubs, vineyards, not to mention seedlings, vegetable plants and ornamental flowers.

The pest is not indifferent to the tubers and root systems of potatoes, beets, corn, and for its special addiction to cabbage, the people called the bear a “cabbage”.

For an effective fight against the bear, it is necessary to use an exclusively integrated approach, including the use of all available means, both chemical and folk.

Folk remedies

For prevention, to limit the access of the bear from neighboring sites, many gardeners are fenced with slate or sheet iron, burying these materials around the perimeter of the garden to a depth of sixty centimeters. Such a shield is a reliable defense against the bear, as it blocks access from the outside.

If there is an opportunity to fence off neighbors, do it, and then the fight against the pest inside the site will become much easier and more successful.

When digging the soil, gardeners often stumble on pest nests. The found masonry must be carefully excavated (along with the ground) and stored in a prepared bucket of water.

In the spring, as soon as the soil warms up and thaws, it is useful to lay out pieces of broken slate, unnecessary boards or sheets of plywood right on the beds. The little bear will certainly come out to bask in the sun and climb under them, and gardeners will only have to systematically check these impromptu traps and immediately destroy all the discovered insects.

In the fall, to combat the bear, it is effective to use hunting pits. To do this, in September, on the site, you need to dig small indentations (up to fifty centimeters) in the ground, which are then filled with manure or humus.

It is noted that the bear is not indifferent to the smell of beer, therefore, two to three tablespoons of this drink and one tablespoon of unrefined vegetable oil can be added to the contents of the formed pit.

According to a similar principle, you can catch a bear in the spring, laying out in several places of the bait of fresh manure (at least two traps for every hundred square meters of land). Once a week, hunting pits must be inspected, and the bear and masonry destroyed. The main thing when examining the fossa is not to make noise, and when you see the bear, do not hesitate, otherwise it will disappear instantly.

It has long been noted that the bear is intolerant of pungent and strong odors, so it does not tolerate calendula, parsley, and garlic. Knowing this, gardeners next to potatoes (between rows) sow precisely these crops, as well as marigolds (small ones are better, because large ones will obscure the plants), or Turkish cloves.

Some vegetable growers, to scare away pests with a fresh smell of alder, stick stakes of this tree species in the ground or arrange fresh odorous alder twigs (one and a half meters apart) throughout the plot.

In addition, the bear is also scared off by the husks of onions, garlic and pine needles (both old and fresh).

Using any of the above methods, you have the opportunity to catch a live bear, so do not forget that if there are fishermen among your friends or acquaintances, try to keep this insect alive for them.

Fishermen will be incredibly happy because they will get in her face an excellent bait for catching large fish, such as catfish.

Another way to catch insects, although it is time-consuming, but very effective.

If massive underground pest tunnels are found, it is necessary to pour a solution of washing powder directly into fresh passages (for this, two tablespoons of any detergent are diluted in ten liters of water).

As soon as the water with the powder is absorbed into the ground, after one or two minutes the bear crawls out and is immediately destroyed (for example, cut with a shovel). With this method of catching pests, it is necessary to observe silence and have a quick reaction.

And the last way. It has been proven in practice that if you take a small crushed egg shell and moisten it with unrefined vegetable oil, and then dig it somewhere on the site (preferably in places where the pests live), then the bear will die soon after eating such a “treat”. Take note.

Chemical methods of pest control

Before using pesticides, it must be remembered that they are toxic and, if used improperly, can cause irreparable damage to the environment, since birds, beneficial insects, and even domestic animals can die.

Currently, there are several drugs on sale (in granules): Grizzly, Thunder, Medvetox. When planting cultivated plants (potatoes, seedlings or various seeds), these granules must be decomposed from them at a distance of five to ten centimeters.

It is best to lay granules in shallow grooves (about three to four centimeters deep) that can be built between rows.

Poison grooves, after they have been laid out and dug, it is advisable to pour water, because the bear prefers to use soaked granules, which it quickly finds by smell. The protective effect of the preparations in granules is about a month.

Another effective way to deal with the pest is as follows: you need to take an enameled mug, pour ordinary wheat into it (fill the mug with grain about four centimeters) and boil for forty minutes.

When the grain is boiled, drain the water, allow to cool to a warm state, and then add one package of the Regent preparation to the grain, which is most often used for pickling the Colorado potato beetle. Mix the solution.

The resulting "drug" to invest in each hole when planting seedlings. Ten etched grains are enough for one hole. The result will impress you.

Fighting the Bear

Medvedka (Gryllotalpa) - an insect that feeds on small animals and plants and causes great damage to gardens with well-groomed, rich humus, moistened or regularly irrigated soil.

Pests of crops are: common bear (G. gryllotalpa L.), single-spike bear (G. unispina Sauss.), Far Eastern bear (G. africana Pal.) - they damage the roots and root necks of plants, as well as root crops and bulbs sown seeds.

The bear reaches a length of 6 cm and has a rigid body with wings, strong horny jaws; the highly developed forelegs of the bear are digging - adapted for digging underground passages in the soil.

The pest was called the “bear” for the clumsy, densely pubescent dark brown body of adult individuals; for the gray color of young larvae and pirate manners it is also called the “spinning top”, for the presence of claws with a serrated nail file - “earthen cancer”; also called "cabbage" and "cabbage" (probably for a special addiction to cabbage).

Medvedka digs in the soil the main vertical course up to 120 cm deep, ending in a horizontal section for wintering of adults; larvae of the first year winter in a vertical course at a depth of 70-80 cm.

In the spring, upon the onset of heat, the bear in search of food make numerous horizontal passages in the soil at a depth of about 2-5 cm, which communicate with the minks and the main vertical pass.

During the breeding season (May, June), the bear appears on the surface of the earth.Near the main course, the bears arrange at a depth of 10-20 cm a special nest-cave measuring 6x6 cm, compacting the soil inside it.

There they lay in heaps dark yellow eggs with a diameter of about 4-5 mm in an amount of 300-500 pcs. After 2 weeks, motile gray larvae emerge from the eggs, leaving the nest after the first molt in late June-early July.

The length of the larvae of the bear varies from 5-6 to 20-30 mm; they look like an adult insect, but do not have wings (larvae complete their development in the summer of next year).

It is recommended to use the mechanical method of agronomic techniques for fighting the bear: early spring and deep autumn plowing, deep loosening of the soil by 15 cm throughout the growing season - these methods destroy the bear’s moves and make it difficult for her to get food, destroy eggs and larvae.

In areas infected with the bear, you can not feed the plants with fresh mullein - it will attract a pest from the entire district. Divorced bird droppings, on the contrary, scare away the bear (you need to water the ground in dry weather with infusion of chicken droppings).

Marigolds, sown along the boundaries of the site, block access to the bear from neighboring territories - the bear does not tolerate the smell of marigolds.

In autumn, when the temperature of the soil is not lower than +8 degrees, it is recommended to dig fishing holes 50-60 cm deep in areas infected with the bear (they dig at least two holes per 100 square meters of the territory), cover the bottom and walls with old film and fill the holes with half-rotten manure - in them the bear climbs for the winter.

With the onset of stable frosts, dung with cubs is scattered on the surface of the earth and the cubs die from the cold.

After lowering the temperature of the soil to +5 degrees and below, the cubs become inactive and mostly settle in the vertical course - this should be taken into account in the manufacture of hunting pits without delaying their excavation until late autumn.

Bears crawl into the manure for laying eggs; the larvae hatching from the eggs at first do not leave the nests in heaps and feed on manure. After 3-4 weeks, the manure along with the larvae is removed and burned, or laid in specially equipped pits.

The use of chemical methods to protect the garden from the bear is recommended only as a last resort, when other methods are insufficient. The drug "Thunder" in small granules (it is effective, but carcinogenic and requires careful handling), pour 3-4 pieces per course and sprinkle with soil. Similarly used less toxic drug "Phenaxinum".

In the spring, before the emergence of plants, for the bear, baits are prepared from corn, barley, rye, and wheat. It is important to prepare and decompose the bait just before the emergence of seedlings - otherwise the bears begin to feed on young plants and almost do not eat the bait.

Up to 0.8 kg of seeds are consumed per 1000 square meters, evenly distributing them over the soil surface, sealed with a rake and watered. Zinc phosphide is also used as poison (per 1 kg of dry grain - 50 g of the drug, adding 3% of sunflower oil); mix thoroughly and close to a depth of 3-5 cm

Bears by smell find the bait, eat and die. Poisoned insects are regularly collected from the surface of the earth and destroyed so that they are not glued and the birds are not poisoned.

In summer, such a method of dealing with a bear is also used: a few drops of sunflower oil are poured into the opening of the course of the bear and immediately 1-2 liters of water are poured from the watering can. After a few minutes, the bear comes to the surface of the soil and dies.

When planting seedlings in the ground, they protect plants from the bear with the help of cylinder-cups from plastic bottles, raising the edges of the cylinder above the ground during planting.

It is practiced to fill the bear’s moves with soapy water, dissolving 10 g of laundry soap and 50 g of laundry detergent in a bucket of water. After 1-2 minutes after pouring about 0.5 liters of soapy water (then you can pour clean water into the hole) into the hole, the bear dies underground or comes to the surface where it is collected and destroyed.

Experience S.I. Milestone: “I noticed that where the bear harms, the plants wilt. In these places, I carefully remove the topsoil until an annular course is detected. If you dig even more, a nesting chamber will open, and next to it are two minks that go deep into where the pest is hiding. It remains to fill these shelters with soapy water and after a while to catch the crawled out insect. ”

Experience A.D. Alekseenko: “Early in the spring, when preparing beds in the garden and in the greenhouse, between rows of plantings, I lay a board on the ground, stand on it to compact the soil, raise the board and dig a trap - a glass jar, the neck of which is lubricated with honey on the inside.

I dig a jar into the soil along the neck and lay a board on top with a gap of 1.5 cm so that the bear can climb into the trap; I periodically check the traps and remove the pests that got into them. ”

Experience N.P. Gryazeva: “I collect eggshells in winter and grind them into powder; in the spring during planting, egg powder soaked in vegetable oil, I put a teaspoon in the planting holes - having tasted this bait, the bear dies. ”

Experience N.I. Polovtseva: “Before digging the site, I tear out a trench deep on the bayonet of a shovel and half a meter wide, fill it with water from a hose and then let out a small regulated stream from the hose to maintain the required water level in the trench. I’m throwing lumps of soil with a bear into a trench and digging up pests. ”

In May-June, I carefully dug up empty soil and loosened sown ridges, when weeding, I looked for open holes of holes and wilted plants, destroying the nests found - after all, during the laying period, the bear does not make deep passages in the soil (mechanical destruction of the incubator nest at this time violates it temperature regime that destroys eggs and larvae).

“I didn’t use non-ecological chemical methods of fighting a bear - I didn’t want to pollute the soil in the garden with pesticides and destroy useful insects and birds.”

Experience Yu.P. Minin for the protection of tulips from the bear: “Before planting tulips, I dig a wide trench for several rows of bulbs, scatter full mineral fertilizer along the bottom of the trench, on top of it a sand layer 2-3 cm thick.

Once again, I scatter full mineral fertilizer from above and cover everything with black soil 5-6 cm thick. With this planting, tulips do not bury. During the digging of tulip bulbs, having removed the top layer of earth to the sand with a shovel, I pull the net by the ends and choose from it the bulbs and the baby - not a single one is lost.

And most importantly - the bulbs are not damaged by the bear, although before, up to 40% of the bulbs were gnawed.It turns out that the bear does not like sand, since its moves collapse in it. Therefore, the area with the sand of the bear passes by. ”

The healing benefits of the bear

Medvedka - a large insect akin to the locust, which lives in floodplains of rivers and land. But, despite all its external ugliness and great harmfulness to gardens, for humans this insect is simply a unique find, the healing properties of which among some peoples have been known since ancient times.

Recently, the beneficial healing properties of this insect were confirmed at the Pasteur Institute in Paris, the institute is a world leader in the study of infectious diseases.

Of course, the bear’s maximum medicinal properties during life, but such humanity has not yet learned to use it, therefore the most common variants of its dosage forms are: dried insects and tincture.

Tincture is used relatively rarely, but dried bear is used quite often, as a rule, to fight cancer (lung cancer) and tuberculosis.

Also in Asia, a bear successfully treats kidneys and relieves swelling (ascites, dropsy), swelling of the legs, treats lymph nodes tuberculosis in the neck, difficulty urinating (Dysuria), gout, is used to treat cirrhosis and liver cancer, chronic hepatitis, it has diuretics characteristics.

All the benefits of this insect, even dried, in its white blood cells - leukocytes, and a special enzyme ferase, capable of dissolving the waxy shell of tubercle bacillus literally within half an hour.

As a result, Koch’s wand becomes defenseless against the body’s immune system, where it is present, and with drugs that people use to fight the disease. The patient begins to recover.

First, this manifests itself in improving appetite and facilitating breathing, and then in reducing coughing attacks. Moreover, this applies not only to the initial (mild) forms of tuberculosis, but also to more severe ones, both to those that are not amenable to medical treatment, and to those that doctors unsuccessfully try to treat.

Successfully helps the bear with various tumors and inflammations, including it is taken to treat cancer. (In these cases, it is recommended to take from 8 courses.)

Bear: insect, its life, habitat and behavior

Bears are representatives of the family Gryllotalpidae (Gryllotalpa literally translated as “molecrick”). Her relatives include all Orthoptera. In its appearance, the bear is very similar to the mole, just like its life.

On the lower leg of her hind legs are thorns in the amount of 4 or 5 pieces. This feature distinguishes the bear from its close counterparts of other species. The body can reach a length of 5 cm. Many other crickets have an ovipositor; it does not have it. The body of the bear has a brown shade and is completely covered with thick golden-colored hairs. The length of its antennae is rather short.

The diet of the bear is made up of roots and insects found underground. In the daytime, these animals hatch in their underground minks and passages, and at night they are selected for food and for flights. Yes they really fly well.

Thus they find new places for their settlement. In summer, the bear digs passages at a depth of 10-20 cm from the surface, and in winter it can dig into a depth of 1 m.

The chatter of a bear is many times greater than the sounds of a cricket. For example, the sound power of a cricket is 0.06 mW, and for a bear, 1.2 mW. A person is able to hear such a sound at a distance of 600 m. When a bear mumbles, her oxygen consumption increases 10 times due to the work of muscles.

Not only males chatter at the bear, but also females. In the afternoon, they behave calmer and make sounds less quiet. Experts say that these animals learned to communicate with each other using identification signals.

Most predators determine the location of the orthoptera by their characteristic sounds. Hunter birds find the bear in this way.

One such clutch can number about 600 eggs. The female does not bury her eggs in the ground. The development of the larvae of the bear is a long process, sometimes lasting 2 years.

Almost all the orthoptera, newly hatched, are characterized by independence and good mobility. In addition, many of them immediately see well. But the bear is an exception to this rule.

Therefore, in newborns, small and limited mobility is present. They are pale yellow in color and do not see until the first age of molting has passed. Their goiter contains a yolk, due to which they survive. The adult stage of development, when the bears are able to breed, begins after 8-10 links.

If we conduct a comparative analysis of the bear and any other orthoptera, then it seems that the bear is born not quite full-term. In other species, the moment they hatch is considered the middle of development in the egg (embryonic development).

Such a process is called "deembryo". The importance of such a phenomenon in evolution cannot be overestimated. Desembryo and embryo (reverse process) allow you to "take from the egg" or "put in the egg" any important signs. Thus, the hatched individual will have this trait in its finished form.

Medvedka refers to pests in gardens that spoil the ground fruits and underground parts of many vegetables and plants, it is also often referred to in the literature as a folk potion for various serious ailments. Medvedka are found in the European part of Russia, with the exception of the north, the Caucasus and Central Asia.

In addition to the common bear, in Russia (the Ussuri region) there is also the bear Gryllotalpa africana. This variety can be found in India, Africa and China.

True connoisseurs talk about its beneficial properties, as it contains many micronutrients. A deep fried bear, served in the restaurant as an appetizer for cold beer.

How to deal with a bear in the garden

A well-kept area with a variety of vegetable crops and shrubs attracts a dangerous insect. The pest regales on young herbs, tubers, roots. The more labor a landowner puts into cultivating a rich crop, the higher the risk that cabbage will be chosen by this particular garden.

Loose, well-fertilized soil in which it is convenient to dig in and make moves is another reason why the bear lives in the gardens of caring owners. The insect of the bear is picky - it does not eat weeds. For this reason, the pest never settles in abandoned areas.

How to recognize

The folk name of the bear is cabbage: the creature eagerly eats succulent leaves and heads of cabbage. It is no coincidence that the pest is called in another way - earthen cancer. It is easy to understand why gardeners dubbed the insect so.

What does the bear look like? Characteristics:

• the body is covered with a hard shell of brown color resembling the chitinous cover of crustaceans;
• adult cabbage can not be crushed by fingers, unlike many beetles and larvae;
• powerful forelegs with outgrowths, whiskers, processes at the end of the abdomen, similar to an oven grip, a large head give the insect a formidable look. A creature dangerous to the garden resembles a small copy of a monster from science fiction films;
• with an abundance of food, adults grow to 5-6 cm;
• the larvae of the bear are large, milky white with spots on their sides. The view is unpleasant - a fat individual with short legs, powerful jaws and a yellow-brown head;
• wings allow an adult bear to fly from one garden to another in search of food;
• the female lays up to hundreds or more eggs. If the owner did not notice the appearance of the bear in the garden in time, you can forget about a good harvest: the omnivorous insect that has bred on the site gnaws tubers, shrub roots, and greens.

The main problem is the omnivorous earthen cancer. Few insects destroy so many underground parts of plants in the garden by eating:

Another unpleasant moment - the bear breaks through multi-level passages in the soil. The cabbage woman spends most of the time underground in search of food.

The insect with powerful jaws does not stop the roots of trees and shrubs: the bear gnaws at everything in its path. If several individuals settled on the site, voracious larvae appeared, most of the area at different depths will be covered with burrows and underground passages.

The pest hibernates in the ground. The insect digs deep burrows closer to the roots of the plants, so that in early spring immediately eat young roots and tubers. Experienced gardeners recommend destroying the insect in the fall and spring, while the cabbage has not had time to actively breed.

Mechanical methods

To understand that the bear live on the site, you can on small mounds of peculiarly rolled up lumps of soil on its surface, which are especially noticeable after rain. The highest activity of these insects can be observed in May, when the bear crawl out of the already warmed land.

It was at this time that you should dig shallow holes on the site and fill them with chopped straw or fresh manure. Bears crawl into the egg-laying pits so that the hatched larvae can eat manure or straw. After 3-4 weeks, the contents of the traps along with the larvae are removed and burned.

Carefully dig out the nests, put them in a bucket, and then destroy them. Try to do this so that the female does not crawl to the surface. Take the pesticide and spread its granules in all the moves leading from the nest - this way you will destroy the female.

There is another way to get rid of the bear. Once you find the nest, fill it with soapy water so that it fills all the passages dug by the insect. From the soap solution, both the larvae and the female will die if it is in one of the passages.

If she is not there, be prepared for the fact that after a while in the same place the female will again make a nest and lay eggs in it. The soap solution is prepared as follows: 10 g of grated laundry soap and 50 g of washing powder are dissolved in a bucket of water.

Instead of a soap solution, you can use water with vegetable oil to fill the aisles - stir a tablespoon of oil in 4 liters of water - or water with kerosene - 100 g of kerosene per bucket of water at the rate of 30 g of solution for each hole.

If the bear was discovered by you near the end of the growing season, wait for autumn and dig soil pits 50-60 cm deep at a soil temperature of at least 8 ºC, line the bottom and walls of the pits with plastic wrap, fill them with started manure and close them with an impromptu lid.

As soon as steady frosts come, get the dung out of the pits along with the bear cubs, who crawled into a warm shelter for the winter, and scatter around the site. Bears will die from frost, because even at a temperature of +5 ºC they become inactive.

Remedies for the bear (drugs)

Pesticides are also fighting in the garden with pesticides, however, chemicals from the little ones are used only as a last resort, when other methods of fighting were ineffective. Several effective remedies for the bear are known:

Fighting folk remedies

How to destroy a bear with chemical and mechanical means, we told you, but there are many effective folk methods and ways to deal with this pest that destroy or scare the bear away without harming useful insects, animals and people.

How to get rid of a bear with onion infusion? In order to prepare this miracle cure, one kilogram of husk and onion waste is poured into 10 liters of water and infused for 4-6 days, after which the infusion is filtered and diluted with water in a 1: 5 ratio. Watering the site with onion infusion is carried out after rain.

The device of traps, for example, with beer or honey, also refers to folk methods of fighting a bear. How to bring a bear using such traps? Dig a plastic container or glass jar into the soil, treating them from the inside to a quarter of the height with honey for bait, cover the jar with a sheet of iron on top and sprinkle it with straw.

Or dig a half-liter can with half a glass of fresh beer, tilt it with thick cardboard or iron, and after a week and a half dig up traps with pests that have got into them.

The bear will certainly appear in order to enjoy this fragrant “dessert”, which will lead to its death, and the eggshell will become a good fertilizer for young plants.

Preventative treatment

It is much easier to prevent the bear from entering the plot than to fight it later. A bear will not appear in the garden if you dig the soil every autumn to the depth of the bayonet of a shovel - larvae and adults will die from the cold.

The preventive measure against the appearance of the bear in the garden can be the refusal to use manure as a fertilizer for plants, since it is with it that the pest most often gets to the site. You can replace manure with chicken droppings.

The bear prevents the appearance of garlic, cilantro, coriander, parsley, marigold, calendula or chrysanthemum planted in the aisles. He does not like the pest of needles and fresh alder leaves that are dug in grooves along the perimeter of the beds. They say that a good scarecrow is a bear - poured into deep furrows around naphthalene beds.

You can scare away the bear in the greenhouse using a mixture of sand and kerosene at the rate of 1 kg of sand and 50-70 ml of kerosene per m² of bed: pour sand with kerosene, mix it thoroughly, toss a few shovels of dry earth to the sand and mix everything again. When planting seedlings, scatter this soil mixture on the surface of the beds and evenly mix it with the topsoil.

Reliable protection against the bear is given by processing when planting the root system of seedlings with a suspension of Actara or Prestige. And those who are not bothered by the smell of rotten fish can use this method of scaring away the pest: when planting seedlings in the ground, they put small fresh fish in each hole.

When the fish begins to rot, the smell of decomposition repels the bear, and she leaves. True, she can go not far - to the neighboring garden.

Plants with an unbranched root system can be saved from the bear by digging a cut plastic bottle into the hole and planting a seedling in it. This "armor" does not allow the pest to get close to the roots and stems of the plant.

Well, it would be nice to enlist the support of biological enemies of the bear, which are birds (storks, rooks, crows, starlings) and insectivores - shrews, hedgehogs, moles, lizards, ants, scolopendra or ground beetles.

If you attract the most harmless of them to your site, you may never know what an ordinary bear looks like.

The best are methods that take into account the nature of the pest. In order to get rid of the bear, it is necessary in spring and early summer to carry out the cultivation of row-spacings to a depth of 15-20 cm to detect and destroy insect nests.

In autumn, when a bear cub seeks refuge for wintering, it is effective to dig holes in the ground with a depth of 0.5-0.7 m and fill them with manure. Such pits are attractive to them, they climb into manure, and when frost begins, manure must be removed from the pits and scattered on the surface of the soil. Both adult insects and larvae cannot stand the cold and die.

When laying greenhouses, it is necessary to carefully examine the soil for the detection of adult insects or nests, around the greenhouse it is necessary to dig hunting grooves. From manure intended for greenhouses, you need to choose and destroy the bear. Knowing what a bear looks like, you definitely will not lose sight of it.
