Together with their furry faces, nearsighted eyes and oversized front nails, moles appear anything but threatening, and they eat grubs and worms, not just the vegetables you cultivated all night. Nevertheless, their tunnels do as much damage to a lawn or garden that most men and women believe them little more than cute pests. If you don’t have the belly for skewering or crushing scars with traps, then you may regard repelling them with devices that are vibrating as a humane alternative. You aren’t likely to have much success, however, unless you’ve got several such devices and supplement them with other mole control tactics.

Walk across the yard or lawn and find as many active tunnel gaps as possible. You can tell if an opening is active by stepping on it and closing it away. The mole will return and dig it out — generally from the next day — when it’s an active opening.

Place a vibrating or ultrasonic unit from the bottom near every opening except one and turn them on. If the vibrations scare the moles, they’ll make their way to the tunnel opening that isn’t protected by means of a device to escape.

Increase your probability of success by baiting the unguarded opening using poison grubs, available at many garden centres. As the moles make their escape, they may be tempted to eat.

Close off the devices after 24 hours, then leave them away for several days and turn them on again for 24 hours. Continue turning them off and on at irregular intervals to prevent the moles from growing accustomed to the vibrations and ignoring them.
