Ok so they aren't a problem i don't know how to deal with. i have a barn with various feeds in it. currently i use a verity if rat control methods. 1) steel traps on the rafters, unbaited. when i feed up in the morning i have 10 to 15 dead rats hanging from the rafters. they use the rafters as highways. 2) barrel traps. 55 gallon drums with a inch of feed in the bottom under steps and close to work benches. i have 4. rat jumps in and can't get out. you've heard of shooting fish in a barrel. i shoot rats in a barrel. maybe 10 to 30 in each barrel each morning. 3) assorted regular rat traps. hit and miss on catching them. use peanuts held on with bread ties. 4) 4 cats. i never feed them but i suspect the lazy jokers are eating the rats i kill in the traps instead of working for a living. i usually just throw the rats out the door. 5) redneck games. a cooler of beer, a flashlight, and a pistol with rat shot. yes i'm easily amused. 6) 1 barn owl. for now i'm letting him stay in the barn. if he takes a biddy this spring then he's getting evicted. what i want to know is any other ideas of getting rid of these vermin. no poison. i'm all for catch and release on animals that haven't harmed me or mine yet, however rats die. i know i'll probably never get rid of all of them. i just thought i'd ask fresh minds for suggestions.
