Pasyuk (gray barn rat) - the most unpleasant and widespread rodent. Every day, colonies of these pests cause irreparable damage to agriculture, berry and forest plantations.
They can pose a danger to pets and human he alth, as they are carriers of serious diseases.
Gardeners need to be able to properly deal with them and protect their territory from such unwanted guests.
Description of the pasyuk rat
The animal belongs to the order of rodents and to the genus of mammals. It is considered the largest rat that lives in nature in Russia.
The main characteristics of the animal: the pasyuk rat is a gray, ordinary, rat. It has an elongated body 20-27 cm long, weighs 150-400 g, tail length 19-21 cm. Paws are pink, clawed, skeletal. The barn rat has a wide muzzle and a light mustache. The ears are pointed with a pinkish tint. The color of the fur is grayish, close to agouti, whitish belly. The border between the color of the barrels and the belly is clearly traced. The fur of young individuals is gray, with age a redhead slips through it. Sometimes in nature there are ordinary black rats. The hairs are quite hard, have different lengths, the guard hairs stand out - those that are more shiny and long.
Origin of the species
Scientists believe that this type of rat appeared in the eastern territory of China. They were brought to Europe on merchant ships through maritime communication between countries. The scientific name "Norwegian rat" acquired in 1769 due to the mistake of the English biologist John Berkenhout, who made the rash conclusion that the rodents came to Denmark on industrial ships from Norway, although at that time they were not yet in that country.
Distribution and reproduction
In various parts of the world you can meet these rodents. They achieved wide distribution due to passive movement on merchant ships.
In the early 18th century, these rodents began to be found in every part of Europe, including Russia. Their habitat can be any part of the planet where there is water and food, as well as climatic conditions favorable for survival.
The barn rat is very fertile. She reaches puberty at three months. At the age of one year, it can produce a brood of about 7-10 individuals. One can imagine how many offspring a year appear everywhere. Pasyuk is considered one of the most prolific rodents on the planet.
Lifestyle
The way of life of ordinary rats is twilight. The activity of these individuals is manifested from seven in the evening to eight in the morning, at ten o'clock in the eveningmaximum peak. They can also crawl out of their shelters during the daytime, if there is any need for this. They live in colonies or groups, rather aggressively protect their territory from strangers. Recognize members of their pack by smell.
Refugees in nature for them are: stumps, snags, burrows, ruined nests. In an urban environment, they most often live in garbage dumps, basements, landfills and sewers.
Food
Food consists of plant foods, fish and meat, grains, any food waste. Many animals can envy the vitality and stamina of pasyukov. They have high adaptive capabilities, have flexibility of mind, swim and dive well, jump up to 80 cm, reach speeds of up to 10-12 km/h.
Harm
Barn rats in the household cause a lot of harm. Rodents drag away and eat crops of beans, beans, grains from barns. Disable storage containers, boxes, boxes, bags, gnaw fruits and vegetables. In suburban garden plots, pests prefer to eat vegetables, berries, fruits, roots of plants and garden flowers.
Gray rats gnaw through the walls of barns, buildings, spoil furniture, wires. After their teeth, not only does the appearance of the living space become unaesthetic, damage to the wiring can lead to short circuits and fires.
The rat is not only dangerous for human he alth. Often there are cases when rodents attack pets.
Waysrodent control
The most effective and best rat control products to exterminate them should be considered.
Poisonous substances are sold in large quantities in specialized stores. Varieties of poisons can be conditionally divided into strong and weak. The first category includes zinc phosphate and phosphide. It's a fast acting poison. When it enters the stomach, it reacts with hydrochloric acid, which produces hydrogen phosphorous, which stops breathing. To kill a rat, a three percent concentration of poison will do. On the plus side, if a poisoned rat is eaten by other animals, it won't cause poisoning in them.
For the fight against small rodents, long-acting poisons are more suitable. It will take quite a long time until a sufficient amount of the substance accumulates in the body to destroy the animal. The body of the gray rat is resistant to poison, and this can be addictive, so the type of substance will have to be changed from time to time.
How poison is used
Main uses include:
- Poisons impregnated with delicacy: bread, cheese, pieces of meat, grain. This method is the most effective in the common one.
- More chemicals dissolve in water, milk - liquid baits.
- Powder chemicals. They pollinate the exit from the hole and other places where gray rats can be seen
- Gas chemicals. They can be used to irrigate burrows, but this method should be used with caution, especially in areas where people live.
Mechanical Traps
You shouldn't charge the mousetrap at full capacity, the rat needs to get used to the left treat. In this case, they will not suspect that the trap will soon work and slam shut.
Arrangement of mousetraps is the easiest way, but unreliable. The size of a barn rat is larger than a vole, so a simple standard mousetrap will not work for it. In addition, after catching a rodent and successfully escaping it, 1/2 of the rats will not come back even for the most exquisite bait.
Ultrasonic repellers
This method is quite effective. Ultrasonic waves have a negative impact on the psyche of rodents, which makes them leave the territory they previously inhabited. But to achieve a good result, the device must work on an ongoing basis. In addition, when buying a device, it is necessary to take into account on what size territory it will be used and what is the duration of the emitted wave. For sheds and barns, a standard universal repeller is suitable. However, if the unit is to be installed in a larger area, several units must be purchased.
Overlapping paths
In order to get rid of rats in a barn or house, you can use another good way - blocking the paths. To do this, it is necessary to calculate all the passages and paths along which the rat sneaks into the house and sprinkle calcium chloride near them, these animals do not tolerate it. More rat loopholes and passages are covered with cement withcrushed glass, it will be extremely difficult to gnaw through such a wall.
If a rat is wound up, all means are good to deal with it. To achieve an effective result, you should not dwell on any particular method, but rather combine them or change them periodically. And do not delay the destruction of the rats, so as not to aggravate the situation.
