Ok Juicy fruit does not work! Neither does a radio stuffed down the hole, the beeping thing from Lowe's, Hair, nope, smoke bombs, funny... The only thing that kills these pests are poison and my cats. The "gummy worms" poisons are the best because worms are what these guys naturally eat. The reason they dig around the liner is because the ground is easier to move. Under Rail Road Ties are their favorite place to dig their tunnels. (I had in a run in my yard over 100 feet) This is because the ground stays moist under the ties and makes for easier digging. (Wish I had known this BEFORE I built my ponds' retaining wall with RR Ties. They are territorial and will not use eachothers runs, but once you get rid of one, another will take over their run. My yard backs up to a 10 acre marion berry farm so there is no way to "flush them out with a hose, their runs are just too long. Do I sound like an expert??? Can't tell you how much $ and how many hours of research I have done just to find another @&*$?@@!ing hole the next day. UGGGHHH
PS J. W. You're killin' me! Releasing them in the woods...which probably backs up to a marion berry field... ; )
