Often, such a pest as a bear is a lot of trouble, so getting rid of this insect and its larvae is always important.
Medvedka leads an underground lifestyle, so sometimes gardeners can't even immediately understand why the plants suddenly began to die.
After the mating process, the female insect builds a nest, which is a rounded cave about 10 centimeters long.
Such a nest lies at a depth of 10-15 cm, it is in it that she leaves eggs, the number of which can reach 500 pieces. To prevent the eggs from becoming moldy, the bear turns them over from time to time and examines them carefully.
Eggs are oblong balls that look like small grains. Eggs can vary in color from beige to yellow-brown with a slight bloom. The clutch of eggs looks like an ant, only the eggs themselves are slightly larger in size.
Since eggs need warmth, the bear buries them at a shallow depth, so you don't need to dig deep to find them. Most often they can be found in bumps on the surface of the earth. The bear larvae emerge from the eggs in about 2-3 weeks.

Description of the larva
Larva of a bear able to slightly resemble crickets or six-legged spiders with an elongated body. Their size can be up to 15 mm. The front legs of the larva are turned outward, with them the larva works, raking the ground in front of it.
The appearance of the cabbage larva resembles adult insects, with the difference that it is much smaller in size. During its active development, the insect larva molts five times, after which it matures and becomes quite ready for further reproduction.
The larvae are not able to fully develop in the summer, so they stay overwintering. Part of the already adult insects hibernate with them.
Medvedka is not particularly resistant to cold conditions, therefore, in severe winters, some insects may die. From that how much fat has the insect accumulated, its survival during the winter days, as well as subsequent fertility, will depend.

Many people ask questions: is the bear a poisonous insect or not? Despite its frightening appearance, the insect is not dangerous to humans, but, nevertheless, it does a lot of harm to gardeners and their crops. There are many, both folk and modern ways of destroying it.
The difference between the bear larva and the May beetle
The larva of such a pest as the May beetle is not like a white caterpillar, the size of which reaches 2 cm, and the thickness can be up to 8 mm. The mouth is located in the front of the larva. and three pairs of small paws, which are covered with hairs.
Brown dots can be seen on the sides of the larva of such an insect, and its rear part is slightly darker in color than the rest of the larva.
The bear larva is completely different from the beetle larvae.... When hatching, the larva resembles a small bug, and with each molt it becomes larger in size and takes on a characteristic shape, increasingly resembling an adult bear.

How to fight?
If you do not immediately start fighting the bear, then her cubs and adult pests will remain in place for all the following seasons. Such a pest able to easily dig holes in any type of ground, so the bear can make a hole for herself, regardless of the weather conditions.
It is necessary to fight the bear insect and its larvae as quickly as possible, since both adults and the larvae of this insect are famous for their very high voracity, which means that they are capable of damaging the root system of a large number of plants in a short period of time.
Currently there are several effective meanshelping to get rid of such a pest. The first of them is agrotechnical. It consists in the fact that it is necessary to prepare the soil in advance for planting plants.
In early spring and late autumn, the land must be plowed and dug up. Thus, the egg clutches of the bear, the larvae will be destroyed, as well as the underground passages that have been made are disrupted.
Planting plants such as marigolds around the perimeter of the garden able to permanently rid of the bear and its larvae... The fact is that the smell of this plant scares away underground pests.
Another environmentally friendly way to get rid of bears is to lure insects into vegetable oil. Into the hole left by the bear a couple of droplets of vegetable oil are poured, after which a glass of water is poured into the same place. After a couple of minutes, the bear will appear on the surface of the soil, and after a few more minutes it will die.
You can also fight the pest using modern insecticides. The smell of the granules attracts insects, after which they eat the bait left by them and, getting out, immediately die. When using this method, it is very important to collect all the poisoned bears, since birds can also be poisoned by these insects.
Medvedka is an insect harmful and dangerous for the crop, capable of rapid reproduction. That is why it is important to fight both the bear itself and the larvae and eggs. Controlling the pest is difficult, but it is worth taking the time to kill the insect and thus save most of the crop.
