Nasser Ahmad, who has been assigned the straightforward job title of "Rat Killer", will receive a monthly salary of 15,000 rupees (USD 147), as well as a 2,000-rupee bonus per mission.
Ahmad says he has already killed more than 100,000 rats in the past 19 months, inspired to take action after seeing the wife of a friend hospitalised after being bitten by one of the rodents.
"We have been receiving complaints about the growing number of rodents in the city, which were causing damage to the fabric of houses and shops, and contaminating food," Nasir Ghafoor, the general manager of Water Supply and Sanitation Peshawar, told AFP.
Ahmad, who has thus far done the job with just a hoe, a wheelbarrow and plastic gloves, has been assigned a staff of five, and plans to train others in a bid to tackle Peshawar's rat problem.
