Overall Rating
As with mole smokes, there is no scientific evidence to show that Castor Oil will repel moles. This is an especially labour intensive method of applying it as well! Especially if you have a large garden, it will require many hours for a full application. Even the manufacturers only claim that it will be effective for around 30 days.
If your particular brand of mole does happen to dislike castor oil, this is likely to be more effective than mole smokes since coverage of the entire area may deter them from simply digging new tunnels. Alternatively, they may just dig a little deeper, down where the oil has not penetrated.
If you must try this, at least buy castor oil from your local supermarket and mix it with water and a small amount of environmentally friendly washing-up liquid (as an emulsifier to mix these two immiscible liquids). This will be a far cheaper way of wasting your time.

Verdict
Whether it works or not, an expensive and labour intensive method of mole control.
