I had an exterminator at a Hanesbrands site tell me to use instant mashed potato flakes and pour it down in their tunnels.Leave a bowl of fresh clean water out to encourage them to eat it.They'll take the food down in their dens and feed it to their babies. It may not kill the adults but the babies won't live and the colony will die out eventually.I fed it to mine 3 years and they're gone! Owls,snakes and possums also eat rats.
