In India the farmers hire rat catchers. Some micro-loan program came up with a better device to smoke them out of their holes. So the rat catchers can catch more. They get 50 cents bounty per rat, get to keep the rats, and any rice that the rats had stashed in their holes!
One catcher said now he catches enough rats to not only feed his family, but his wife prepares them and sells them. He is making enough money now to send his kids to school so they won’t have to be rat catchers.
Of course here in the U.S. you would have to promise $50 per rat in order for anyone to get off the front porch and go after them.
In Thailand, at certain times of the year, they beat the rice paddies to run the rats into catchers at the opposite end. Granted, these are not Norway rats (like in NYC) but we used to eat the rats off barbecue stands every night (once we got drunk enough). Sorta like squirrel, but with a ricey taste.
Note to self - if ever in India, don't buy anything from the food carts!
