Maybe I missed something. We're talking about mice here, right? Along with their cousins, the other rodents, these are the scourge of mankind. We're talking Black Death, recurring pandemics** and so on.
I assure you, you'll pay the devil finding a place to re-home wild mice. Releasing them or relocating is equally useless.
I personally have nothing against mice, in general. They are what they are.
But why can we not cut through all the red tape and simply put water in the bucket to drown them?
** Most people have a vague notion of the disease called bubonic plague, or The Black Death of the Middle Ages. Some few know that it is spread through the bite of an infected flea, most often parasites on rats and mice. From them it can spread to both other animals and humans.
But beyond that, they are ignorant of it's effects and causes.
The original bubonic pandemic is thought to have begun in Central Asia or India and spread to Europe during the 1340s. It wiped out roughly half of the population of Europe (30% to 60%) in its initial appearance, not to mention the outbreaks in Aisa and the Near East. This great "die-off" is one of the most influential events in human history, with far reaching effects still felt to this day.
The total number of deaths worldwide is estimated at 75 million people; approximately 25-50 million of which occurred in Europe. It is estimated to have reduced the world's population from an estimated 450 million to between 350 and 375 million by 1400.
But it didn't stop there. Bubonic plague is thought to have returned to Europe every generation with varying virulence and mortalities well into the 1700s. During this period, more than 100 plague epidemics swept across Europe. On its return in 1603, the plague killed 38,000 Londoners. Other notable 17th and 18th century outbreaks were:
The Italian Plague of 1629-1631,
The Great Plague of Seville (1647-1652),
The Great Plague of London (16651666),
The Great Plague of Vienna (1679),
The Great Plague of Marseille in 17201722,
The Great Plague of 1738 (which hit eastern Europe), The 1771 plague in Moscow.
After that, it seems to have disappeared from Europe in the 19th century.
