How did big cities completely eliminate mice? –

mice are animals that cover their body except fur, about nine centimeters long, live near the human environment and feed on many of the foods and tools they use, such as paper, household food, or wood, and have a strong sense of smell. The mouse is an unpopular animal, especially in the fields, because it destroys the plant and causes severe damage, causing great economic losses to the owners of farms, and is not granular in the house also because it is a carrier of diseases and causes of disturbance and unpleasant odors.

Problems of mice around the world:

“I would not deny that I do not like rats or hate them, but I appreciate them,” said Phil Merrill, head of the Rat Control Program in Alberta, Canada.

Norwegian rats, known as brown mice, are characterized by rapid reproduction and large numbers of young people at a time. These mice eat almost everything, from household waste to rotten meat and grains, and live where humans live. As well as being able to chew the metal, swim long distances, and bear the fall of heights up to 50 feet, and may seep into your home from the toilet.

Its original home is said to be northern China, and from there it has spread to all continents except Antarctica. As the numbers of many animals diminish, mice multiply and spread, especially in cities. Mice are the most vulnerable invasive species outside their habitat. Once they invade an area, they damage wildlife, damage property, contaminate food and transport diseases.

The United States spends $ 19 billion a year on rat control, a sixth of what it spends annually on fighting gaseous organisms. In Mumbai, mice cause most of the vehicle fires.

There is no city in the world devoid of mice, with the exception of Alberta, which includes the towns of Calgary and Edmonton, with a population of 4.3 million. Alberta is the only place in the world with so many rural and urban populations and no problem with breeding mice.

Do not let mice escape from you:

“We started the fight against the rats before they reached our eastern border in 1950, and we tried to drive them out,” says Merrill. “We searched all farms along the border from mice and killed them all with poison.

The geographical characteristics played a role in keeping the mice away from the province. The mice do not tolerate cold in the north and do not live in the rugged mountains of the west.

Only the western borders where strict measures of prevention of mice are maintained. The rats arrived in Saskatchewan in the 1920s. Merrill says the government in the neighboring province of Saskatchewan was not ready to invade the mice at the time, but when I reached the Alberta border (30 years later) we already had a Ministry of Health and Agriculture.

And In 1950, rats were included in the pests and became compulsory. The poison was used to kill mice that reached Alberta and treated the buildings that housed them. Control and inspection measures were intensified in one area along the border with Saskatchewan province, called the Mice Control Area, and a pest control team was identified and the area was free of rats.

The government has launched an awareness campaign to help residents distinguish between Norwegian rats and rodents inhabiting the area. Thousands of banners have been published, including slogans to urge people to kill mice, such as “killing mice where they are found. They threaten health, homes and industry.” Some encouraged farmers to keep their farms clean so as not to endanger their neighbors.

What is Nature of Life In mice:

when living in their natural environment, they are animals with night activity. They do not go out of their hiding places to search for food or walk often until after dark, and in rare cases they can go out in daylight. They live in burrows dug underground, they are good at jumping and climbing difficult places, except that many of them can swim in water with excellent efficiency. One type of rat spends almost all of its life under the ground to dig complex, deep, mole-like fossils. The natural environment of rats is the grass meadows and the fields. They dig small grasses among them, consisting mainly of one main chamber, whose land is covered with hay and dry grass, and faces a very large number of natural enemies in their original habitat. Many species of snakes and birds In particular) and medium-sized mammals (such as cats and foxes) are frequently targeted and relied upon as primary food.

Inventory of costs:

Meryl has been working on pest control since 1970 and says some changes have made his job easier, including the modernization of farm buildings and rat control activity in Saskatchewan, where the incidence of mice has declined.

While the cost of the anti-rat program is only $ 500,000 per year, the Alberta Research Council estimated the annual loss of rats in 2004 at C $ 42.5 million annually.

These amounts were estimated on the basis of a US study that assumed that each rat consumes or destroys cereals or other substances valued at about US $ 15 per year. The losses include fire from wire loan, contaminated food and disease related losses.

“There is no doubt that the program has saved the government millions of dollars that would have been wasted in fighting mice every year,” said Larry Roy, co-author of the report.

Follow the Alberta model:

Most rat control projects include eliminating all mice that have spread and proliferated in islands, rather than preventing them from reaching them. The motives of these projects also differ from the motivation behind the Alberta project, which was largely economic.

“Many rat eradication projects rely on loss-for-benefit assessment, but in most cases, these projects aim to conserve wildlife that dominates the place,” says Tony Martin, who led the rat extermination project on South Georgia’s South Georgia island. Not economically motivated. ”

In South Georgia, poisoned baits were thrown from the planes as part of an eight-year, $ 10 million rat extermination project. This project was based on voluntary funds.

Martin sees the Alberta project as an outstanding achievement, because it has managed to keep this vast area completely free of rats.

Martin hails the enthusiasm of the population and sees it as the most important factor in project success. Opposition may discourage people and cause projects to stop. Martin refers to the island of Lord Howe in Australia, where the eradication of mice began only after 20 years of opposition, as well as in New Zealand, which announced an ambitious project to get rid of rodents from abroad by 2050 to protect biodiversity on its territory, But the idea was met with considerable opposition.

Merrill says population support is essential to the success of the project. “People are told about mice as soon as they enter their gardens,” he says, but there are still few opponents of the ban on rat breeding, and some snake breeders call for freezing mice. The rest of the population is happy to get rid of rats.

“We love mice that inhabit our territory, like musk and forest mice, and if these mice can live in nature away from humans, we will not get close to them,” says Merrill. “If we eat our food and waste and invade our homes, we do not want them.”
