We have a had a problem with rats ever since we got a couple of round bales from a local farm. Unfortunately one came with a family of rats in it . We tried every thing from snap traps to water pails to live traps with glue paper . All with some success . But even using all at he same time could not get rid of them . Try putting bricks down to make a hard floor but the

just tunnels under and made highways under it . Finally decided to gas the

things . Do you know how much CO a Onan can make when the choke is half on . LOTS

. We penned the birds off away from coop/ run area for a few hours . prep everything an with some 1" flex exhaust tubing down each hole we gassed the buggers . WOT and half choke we ran the exhaust in to each hole for 10 min. then back filled the holes . Fill all the holes where they were coming and going yesterday . ZERO signs of them today . Hopefully thats the last of them . I am perfer to live and let live for the most part , but there are times you just got to do what you got to do .
