Rats- the gnawing problem underfoot
The common rat is an everyday companion that we know very little about, says S.Ananthanarayanan.
The hopelessness of solving the rat menace is legendary. In the German folk tale, the Pied Piper lures the rats of Hamelin away by his music. On not being given the promised fee, the piper leads away the children of the town.
What the story underscores, however, is the futility of ordinary methods used by municipal services to deal with infestation by rats.
