The common mole is an insectivore, not a rodent. Its diet is restricted to ground invertebrates such as grubs, millipedes, ants and the like. However, the mole's primary food source is earthworm, so trying to control white grub and lawn insects is no protection from mole activity. The activity in certain lawns can simply come and go throughout the season. On large properties the activity may gypsy from one part of the lawn to another. This movement or migrating is controlled by climate and ground moisture. Moles will adapt to changes in food supply and source as different insects become available in different places and at different times throughout the year. Moles will jump home range and readily re-colonize other existing or deserted tunnels. Moles may leave an area if disturbed but will usually return when you least expect it. Even without disturbance mole activity may last only a week or two in a particular area. This here-now gone-tomorrow behavior is probably the root of most of the subjective misconceptions that make some home remedies including moleicides appear credible.
Home remedies are also the root of such remedies as lye, Drano, pickle juice, broken glass, red pepper, razor blades, bleach, moth balls, rose branches, human hair balls, vibrators, ultrasonic contraptions, castor bean derivatives (Mole Med), gasoline and explosives. Although this fun and games approach may relieve frustrations, these and other home remedies have little if any value in controlling moles.
The only way to really eliminate your mole problem is to call a professional.
