The balance of their diet include seeds, grass roots, etc. Earthworms are one of their favorites, and although grubs may attract moles to an area, the elimination of grubs will not remove the moles if there are earthworms present, and conversely, the presence of moles is not a sure sign that you have grubs, especially if it has been treated for grubs. Baits are successful if a mole accidentally eats them while searching for food. The same is true with chewing gum. Castor Oil will move moles temporarily, as will ultra- sonic sound, but not for long.
Traps are effective but time consuming , expensive, and difficult to place properly.
Years of experimentation with every product on the market has led us to a product and program that we believe to be the most effective for mole elimination. The product is a fumigant in tablet form that, when placed directly in the mole run, will instantly kill them. The program consists of three steps including the placement of the fumigant, tamping all runs and hills the following day, returning in one week to be sure all moles were killed, and retreating if necessary. It is a deadly fumigant. Although underground, dogs and small children must be kept off the area for twenty four hours to prevent them from digging in the runs.
