Origin of species of pasyuk
Scientists suggest that the birthplace of a barn rat is eastern territories of China. To Europe they hit through the maritime communication between countries on merchant ships.
The scientific name Rattus norvegicus (Norwegian rat) was acquired by an English biologist John Berkenhout in 1769, who rashly suggested that rodents came to Dania from Norway on industrial vessels, although at that time they were not there yet.
Distribution and reproduction
Gray rats are found in various parts of the world. They managed to achieve wide distribution thanks to passive movement on merchant ships.
They can live anywhere where there is access to water, food, as well as favorable climatic conditions for survival. Barn rats differ in high fecundity.
Puberty occurs by three months. Up to eight litters can be born per year. 7-10 individuals.

Methods of rodent control
Consider the most effective ways to protect homes and land.
Toxic substances
In specialty stores there are many varieties of poisons.
All poisons can be divided into strong and weak actions.
- The first category includes zinc phosphide. Poison acts fast. Once in the stomach, it begins to react with hydrochloric acid and forms phosphorous hydrogen, which stops breathing.
For the death of an animal suitable 3% concentration of poison. Good for not poisoning other animals if they eat a poisoned rat. - Long acting substances more suitable for dealing with small rodents. It may take a little time until the poison accumulates in the body and destroy the animal. In addition, the body of a gray rat is more resistant to poison and can get used to it, so from time to time the appearance of the substance will have to be changed.
In which species can poison be used?
- Poison-soaked delicacies (grain, cheese, bread, pieces of meat). The method is effective and the most common.
- Liquid bait - dissolved chemicals in water, milk.
- Powder chemicals - for pollination of outlets of burrows and other places where granary rats could be seen.
- Gaseous chemicals - used, for example, for irrigation of holes. This method should be applied with caution, especially in residential areas.
Mechanical traps
Arrangement mousek - the easiest way, but not reliable. A barn rat is larger than a vole in size, so the standard simple mousetrap is not suitable for it.
In addition, after catching 1-2 rodents, they do not want to go into a mousetrap even for the most exquisite bait.
Ultrasonic Repeller
Enough effective method. Modern devices operate effectively. Ultrasonic waves adversely affect the psyche of rodents and force them to leave the occupied territories.
Overlapping paths
Another not a bad way to fight. To get rid of gray rats in the house or shed, you can use overlapping paths.
Try to calculate the moves, loopholes, paths along which the pasyk sneaks into the house, and sprinkle around them calcium chloride. Rodents do not tolerate this powder.
Rat loopholes and Strokes can be plastered with cement with crushed glass. It will be extremely difficult for them to gnaw such a wall.
In the fight against the hated gray rodents all ways are good.
For the work to be done effectively, it is better not to dwell on any particular method, but try to change them or use them in combination.
Then even such unpleasant pests as gray rats will not be scary to your home and site.
