Moles eat earthworms and grubworms, not grain, so any kind of poison grain or poison peanuts as I once tried, are really useless. I tried the poison "worms" and nothing happened to show they worked. I've tried a lot of "proven methods" to kill moles that were supposed to work, but didn't. Trapping is the best way, and it takes practice and studying the habits of a mole. A dog that will dig them up is just as good, providing such a critter can be found. My Aussie killed several one summer, then has not bothered them since, so much for that. I have 4 mole traps, 3 of the old spear kind and a scissors trap. I've had better luck with the spear traps, but then again, have used them more. I was told by one expert on moles, to spray my yard for grubs, and I wouldn't have moles, because they wouldn't have food. I have noticed that the areas where I've seen a lot of grubs in the past, are also the areas where the moles seem to also like.
