A man who can trap problem animals fast and effectively, whatever they be, will never be out of work. IMO. There are, however, a lot of pretenders. I hear some right horror stories. A farmer near me had three mole catchers on his fields this winter and all were useless. One caught nothing, one caught one and then lost his traps, and the third caught three. he wanted a tenner a mole and he came to the field for four days I was told. For a grand total of £30....It's amazing how these people make any money....
