When I accidently flooded part of my lawn, I saw the mole making a getaway across the street! All I had was my red rain full of plants. I ran over him and his pointy little head. But it only stunned him. My neighbor saw me and my ruckus and came over with her hammer to finish the job.
I took out another one when I saw the ground pulsating. I hammered a loooong screwdriver into the soil until it came up bloody. Then hammered it all the way in and let it sit there for an hour . Instant burial!
So far, so good this year with no unearthed trails. But I've made double sure the grub worms stayed out of the lawn after all the rain. Plus it helps that the neighbor next door has started to take better care of his lawn.
