The mole's snout is long and slender and admirably suited to assimilating a diet consisting primarily of earthworms with an occasional side dish of grubs or larvae. His habitat is a lengthy network of runways through which he continually roams in search of food. Keeping these fact is mind, let's get on with the most common mole fighting misconceptions. Fumigating your soil with poison gas has a tendency to kill the good bugs and bacteria that assist you in your gardening. Fumigants MAY occasionally kill a mole or at least drive him away, but not consistently.
Fumigants are most likely to work in heavy soil that is saturated by water.
If the bait doesn't have the consistency of a wet noodle, he probably won't eat it. So far, the brands we have tested have been ineffective for quick control. In our tests, moles ignored chewing gum. If you feel compelled to try this method, just remember to keep the stuff well away from your vegetable garden. Environmentally speaking, it's a very unsound practice and technically illegal.
