Rat-catchers were employed in Europe to control rat populations. Keeping the rat population under control was practiced in Europe to prevent the spread of diseases to man, most notoriously the Black Plague and to prevent damage to food supplies. Today this job no longer exists.

What do rat catchers do with rats?

Rat-catchers may attempt to capture rats themselves, or release "ratters", animals trained or naturally skilled at catching them. They may also set a rat trap or other traps.

How much did rat catchers get paid?

De-ratting English manors and businesses earned rat catchers wages that ranged from two shillings to one pound. However, because rat catchers had to make an investment and at least own a terrier or a ferret, many rat catchers were older youths.
