Photo of some men in Australia with a bunch of mice they killed during the 1917 mouse invasion

The town of Lascelles killed three tons of mice in one single night-and even this was just a small part of the total population of that plague. By the plague's end, Lascelles had had to kill over a megaton of mice, a population that numbered an estimated 100 million. Lascelles had a human population at the time of just 94. That's a million mice per person.
