Local farmers hunt the rats, weighing more than a kg each, at night during the harvesting season with traps made of bamboo, to prevent their fields from being damaged by the rodents that eat paddy and other crops.
The farmers claimed that the trapping of the rats was helping them to curb the growing menace of rodents in recent times.
Explaining the method of trapping the rats, a seller said the rodents are hunted at night when they come out of their holes and walk straight into the traps placed by the farmers at the entrance of the rat-holes.
Rat meat is usually sold by the economically challenged people of the Adivasi community to augment their income earned from working in tea gardens, where plucking of tea leaves reduces during the winter season, the sellers said.
"Business is good as we can trap rats weighing 10kg to 20kg a night for selling it in the market," they said.
