You believe every rumor, home remedy or control method is worth trying. Moles are woodland animals in nature, but can quickly colonize and spread through adjacent residential properties if not handled properly. Since they need a well-established tunnel network to survive, the longer they're allowed to tunnel, the more habituated they become and difficult to control.
Trapping is the only effective method of control.
It is literally a war of attrition. Since few homeowners bother to trap moles, large mole populations can develop in residential areas. It seems odd to me that in spite of all knowledgeable sources advocating trapping as the only reliable approach to a mole problem, we're still pouring on the chemicals, pumping the soil full of gases, snapping up sonic noise makers and trying age old home remedies that never have worked. The common mole is an insectivore, not a rodent. Its diet is restricted to ground invertebrates such as grubs, millipedes, ants and the like.
