I admit it - I'm very, very ambivalent about harming any creature, even one that tears up our lawn the way moles do. But after one of our kids fell and nearly broke a leg in one of the numerous mole holes in our yard we (reluctantly) decided to cut down on the mole invasion. We did not want or need another emergency trip to the doctor's office. We also have elderly parents who visit often and the thought of THEIR falling was frightening to us.
