The following content is factual information and honest advice on mole behavior, ecology and mole control. The cheapest and easiest way to deal with mole damage is to pick up the piles of dirt and not step on them. Spread the dirt around. You'll find there is good grass under the dirt and there won't be a large bare spot. Mole tunnels should be walked down to keep the grass from browning out. This won't necessarily get rid of moles but the lawn will look better and the exercise should be beneficial.
Moles can drive you nuts! If you're like most homeowners, you're probably confused by all of the conflicting "advice" on mole control. You believe every rumor, home remedy or control method is worth trying. In fact, chemicals and home remedies (including castor oil derivatives like Mole Med and grub controls) are not only ineffective when dealing with moles, they allow the animals time to establish and become real problems. Moles are woodland animals in nature, but can quickly colonize and spread through adjacent residential properties if not handled properly.
