The past two years I have had mah hands full fightin' these tunnelin' bastages. I applied Grubex last year but it didn't seem to do much. I tried them 'spensive toxic rubber worms with no luck. I even tried to trap them with the standard mole/ground squirrel trap. Nothin'.
SO....yesterday I decided to re-apply what worked in OH so well. It's the YARD ROLLER!!! The sole reason I had not deployed it was because my yard has a lot of slopes and hills and some 500-600lbs. of weight can be tricky to keep from overturning or jack-knifing.
My new lawn tractor I have now is bigger than the one before, and I discovered I could dang near handle any slope with the roller. Nothing kills a mole like that roller! Nothin'!!!
