Hmmph, my moles go after the earthworms, ignore the grubs. So I spread coffee grounds out in the part of the yard they can disturb, then water. It works as well as everything else, until the cats and my dogs get after them. The voles, well, you could shove 50 gals of water down those holes and the trees would say thanx, but it wouldn't even begin to do anything but cool the dirt off for the voles. 3rd year of drought, for once my bugs are minimal, more grasshoppers than anything else, red wasps, even mosquitoes are minimal so far. Deer are starting to move here, tho.
